fatal error: lua5.4/lua.h

[jhalves]

Hi!
First i want to thank you for what you are doing for improving simracing on linux

I just moved to Arch Linux some weeks ago and im trying to make assetto corsa run with all the add-ons i had in windows.
Fist time on Linux and i already managed to run AC with content manager and csp but now i want a replacement for simhub and crewchief and i found your projects.

So ... after reading a lot about all this API packages working together i downloaded and managed do compile simshmbridge, simapi and simd. I put them togheter in a tree and they seem to be working.

if i run ./acshm i got the message "Press q after all processes using shared memory are closed, to release the shared memory files."

if i run ./simd --nodaemon --nomemmap -vv i got the message "Searching for sim data... Press q to quit..."

I also can see the simapi.dat file running on /dev/shm folder

Now .. i downloaded monocoque and put the tree i made from simshmbridge, simapi and simd inside simulatoriapi folder and start compiling ... and when running the "make" command i got this error:

[caracol@archlinux build]$ make
[  2%] Building C object src/monocoque/gameloop/CMakeFiles/gameloop.dir/gameloop.c.o
In file included from /home/caracol/Programas/monocoque-master/src/monocoque/gameloop/gameloop.h:1,

    6 | #include "lua5.4/lua.h"

It says folder or file does not exist.
I installed lua 5.4.7-1 from arch repository and also from source but the error persists.

I searched lua.h file on my disk and there are 2 of them inside:
-/home/caracol/lua-5.4.7/src
-/usr/include

Until here i managed to find a solution for all the errors i found ... most for missing packages but now im stuck on this.

Can you help me out?
Thanks

[jhalves]

solved!

i just made a newlua5.4 dir " /usr/include/lua5.4" and copy lua.h and 2 other from "/usr/include"
compilded ok

haptic test on sound card with bass shaker ok!

moving on :)

[Spacefreak18]

this could be a problem in my cmake, i'll look into it, i just added the lua stuff last week, and didn't update the PKGBUILD or the dependencies on the README yet. I'll leave this open to remind me.

let me know though if you need any help with the config or setting up simshmbridge (and/or simd) for getting the simdata into Linux, but it sounds like you already have those up and running ( you only need one of simd or acshm )

then you also need to run acbridge.exe in the same wine or proton prefix as AC.

run hexdump /dev/shm/acpmf_physics when you're actually in a live session, if it's not all zeros, you're good to go.

[jhalves]

Hi :)
This have been quite a adventure for me since never used linux before:)
And i have many many questions for you :)

right now this is where i am

1 - I start AC in steam with ProtonGE just to open up Content Manager

2 - Run this commands in 3 different konsoles:
./acshm
./acshmstart.sh
./monocoque -dv play

3- Start AC from Content Manager

Results:

1 - achandle starts 4 processes for physics, graphics, statics and crewchief

2 - i get the ac data in monocoque debug (speed, rpms, gear and alt). They all looking good but i dont know what alt is cause its always 1)

3 - i can get the rumbling from rpms on transducers but not from gear (i have booth configured in ~/.config/monocoque/monocoque.config). In monocoque before initialing audio device for gear its says:

everything else on monocoque debug looks good

4 - i configured audio card ID in monocoque.config following your instructions but ... if i have other audio device as default in arch kde thats where monocoquer sinewaves goes (i have to manually change default audio device to the tranducers or setting up route with audio router qpwgraph so i dont loose the AC sound on main speakers)

5 - didnt notice at first but now im getting always audio interferences with a lot of noise like if the connections are failling (i just tested in windows with simhub bass shaker and they just work fine)

6 - i dont see the diameters.config anywhere and cant get any rumbling from road or anything else except from rpms even after following the driving at 70kms/h instructions.

7 - i also tried to set CrewChief but that was a nightmare so i will leave it for later.

8 - after a quick look to your other project simmonitor im wondering if i can make a custom dashboard with ac data running on android or ios phone through web like i do in simhub

Im really trying to quit windows and setting up AC with all add-ons i have in windows is my last demand so i appreciate a lot your work. Would love your help and inputs to finish this so i can finally just enjoy the driving :) Also there is no urgency ... just answer when you find the time ;)

[Spacefreak18]

for a newbie, you're doing really well then lol.

you're right about my other project simmonitor. you could pretty much do anything you want with the simdata to make a ui, provided you write the html/js/css for it. I think i have an examples folder in there with a couple pretty advanced examples.

Ignore "alt". It's altitude, I had a pipe dream that monocoque could be used for flight sims too, hence the name since monocoques are used both in aviation and racing.

diameters.config should be in ~/.config/monocoque. 70km/h, no steering, no accel, no brake, it should come through.

it sounds like all your setup with simshmbridge is perfect, if you're seeing rpms.

Did you compile monocoque with cmake -DUSE_PULSEAUDIO ..; make clean; make?

If you didn't, delete the build folder and do so. I really should make pulseaudio the default. The reason it isn't is portaudio is cross platform, and I intended (still do) for this to be cross platform. (simmonitor not so much)

don't worry, it doesn't depend on the whole pulseaudio backend, just libpulse, so it should work fine with pipewire as I use it.

If you've done all that, post your config and the result of the pacmd command i have in the readme, and I'll try to answer some more.

i use AC with CM and CSP on Linux with all this, fairly reliably so, we should be able to get you setup. :)

[jhalves]

Thanks for quick reply :)

Yes ... im getting all the data from ac into monocoque. My problems now are monocoque/audio driver related and also getting the other wheels/road effects. Tomorow i will try again folowing your new inputs and see how it goes.

Good to know i can use simmonitor for my purposes. I did some coding in other languages like python (for AC Apps), C and SQL for databases... never did html/js/css but maybe its time to learn :)

After setting up bass shakers i will move to CrewChief and will need a lot of help with that (i just see all kind of different winetricks and protontricks prefixes anywhere i search for guidance) ... and none seems to work :)

[Spacefreak18]

last time i installed the newest version of crewchief into it's own wine prefix it "just worked", almost like i was installing it on Windows.

Then after that it's easy, assuming you have everything else setup and you're getting data into /dev/shm/acpmf_physics.

The next step, in the case of AC, would be to make a copy of acbridge.exe and call it acs.exe, and run wine ~/git/simshmbridge/assets/acs.exe.

I look forward to your feedback too on improving things, seeing as you've used Simhub. I haven't used Simhub in a long time and when I did it wasn't for very long.

[jhalves]

so ... no lucky

compiling it for pulse audio made it run without any errors on monocoque debug but got no rumbles at all on transducers
i tried to move from pipewire to pulseaudio but i just broke arch and add to install it all over again
now i understand why people say arch linux is a masoquist hobby :))

i reinstalled with pulseaudio as default audio but its same ... no rumbling at all when compiling with cmake -DUSE_PULSEAUDIO ..
with portaudio no rumblings and a lot of errors on debug ... much more when using pipewire

is there something i need to configure to make it work with pulseaudio? cause i got no errors at all in debug ... everything initializes perfect ... i just got no output

no luck with diameters.config either ... how long do i have to drive at 70km/h? how long without any inputs?

tryed to install crewchief just like i do in windows but when updating the soundpacks was hanging in there already for 10minutes ... will keep trying someother ways

my config at ~/.config/monocoque

configs = ({
    sim = "default";
    // one can also specify sim by using the "short-name" for example "ac". also, "acc", "ace", "ams2", "et", "at" and "rf2"
    //sim = "ac";
    car = "default";
    devices = ( {   device       = "Sound";
                    effect       = "Engine";
                    devid        = "alsa_output.pci-0000_08_00.3.analog-stereo";
                    pan          = 1;
                    volume       = 90;
                    frequency    = 27; },
                {   device       = "Sound";
                    effect       = "Gear"
                    devid        = "alsa_output.pci-0000_08_00.3.analog-stereo";
                    pan          = 1;
                    duration     = .25;
                    volume       = 100;
                    frequency    = 27; }
              );
    });

pactl list sinks | grep -E -i 'index:|name:' -A 4 come out empty now with pulseaudio but i got this jusr by running pactl list sinks

its the same ID i was using before with pipewire

not a good day :)

[jhalves]

And i checked with hexdump /dev/shm/acpmf_physics ... not all zeros at all ... and everytime i run it i got different data. Monocoque debug speed, rpms and gear are also changing acoording to the driving. Everything looks good in shared memory department even if i never run acbridge.exe ... is that strange?

[Spacefreak18]

You don't need to install pulseaudio to use the build with pulseaudio. The pulseaudio build should work with your install with pipewire.

That behavior you mention with Crewchief hanging on the sound packs has been experienced by many of us. I can't explain it, but eventually it will work.

You don't have to drive that long to get the diameters.config to appear, 3-5 seconds?. But are you planning on doing tyre effects? If you're just doing these two effects, there is no need.

I wouldn't worry if you still see data in /dev/shm/acpmf_physics. acshm and simd, should be the first thing you open, and the last thing you close, and they will safely free that file.

Do you have an app called pavucontrol installed? When you have monocoque up and running, you can open this up, and it should show you the audio streams on your system and the process they are coming from and which audio device they are going to, from there it should be easy to identify the streams coming from monocoque and what the issue is. Maybe they're being muted by default somehow. Stick with the pulseaudio builds though, and the basic arch linux pipewire setup.

You may see the audio stream working when you start pavucontrol. And you'll just notice it's an issue with volume or frequency being the reason you can't hear it.

It sounds like it must be working. If all else fails, post here your debug output from monocoque play -vv.

[jhalves]

So im on pipewire again with pulseaudio build.

With simhub i have 4 efects: gear, engine and 2 road effects based on suspension that allow me to feel all the road bumps, kerbs, ... I want to replicate the same with monocoque but its not easy. With pavucontrol I can turn on the rumbles for both gear and engine but they are intermitent ... sometimes work sometimes not. Need to make some more tests and adjustments but its just very inconsistent right now. The engine is like turnig on/off all the time. Maybe need to play with volume or frequency.

How does pan work? Its just one or are there different settings?

Didnt manage to get the diameters.config working yet but i will try again later (didnt try much)

The good news is a got CrewChief working with AC shared memory. Made a prefix called CREWCHIEF with winetricks on ~/.local/share/wineprefixes. Installed in there dotnet 4.7.2 and crewchief.msi and it just worked perfect.

Then renamed acbridge.exe to acs.exe, started Content Manager and CrewChief and finally ran in 3 different Konsoles:

./acshm

./acshmstart.sh

CREWCHIEF_WINEPREFIX="${HOME}/.local/share/wineprefixes/CREWCHIEF"
export WINEPREFIX="${CREWCHIEF_WINEPREFIX}"
export WINEARCH="win64"
wine ~/Programas/simshmbridge/assets/acs.exe

Just couldnt believe it was working :))

Also managed to install and start SimHub but its not working right ... there are probably some dependencies missing.
Do you think it will be possible to pass the shared memory into SimHub in the same way like CrewChief? That would be fantastic!

[Spacefreak18]

pan is the audio channels. i could tell you how to figure out which is left and right, but it shouldn't take long to figure that out. you should try setting pan to 0, but it all depends how you have things physically connected.

you're right, the same process you used to get crewchief to work would work in theory for any program in a separate wine prefix. (and you'd only need to start acshm once for everything) if that makes sense

if you want to hop on the matrix chat (it's in the readme), i can help you out quicker in realtime there.

you say they're intermittent, how do they respond during the monocoque test sequence?

[Spacefreak18]

use this command from the readme to help figure out the pan

ffmpeg -f lavfi -i "sine=f=440" -af "pan=7.1|c1=c0" -f wav pipe:1 | paplay --no-remap --no-remix -d alsa_output.pci-0000_00_1b.0.analog-stereo --volume=65536 -n "Monocoque" --stream-name="Haptic Test"

change the -d to the devid that is in your monocoque.config

play around with the frequency of "sine=f=440" to find one that you can feel correctly in your setup.

change "pan=7.1|c1=c0" for right channel and "pan=7.1|c0=c0" for left channel. (they might be swapped, it actually depends on the loaded sound card profile)

[Spacefreak18]

also pull latest please. i fixed the lua dependency and i made the engine rpm effect use the base frequency you set in the config properly.

you could also try just the gear effect set in the config.

i guess i need to know more about your setup. maybe post the full output to pactl list sinks? are all of these noise transducers connected to the same sound card?

that devid has to point to the device you're using for the effects. because otherwise the frequency will be too low to hear through normal speakers. ( if you try a frequency of 440, and then you hear it through your normal computer speakers, you know you have the wrong devid )

if you try that ffmpeg command it will give you some clues, because you should hear where the tone is coming from. if you hear it out of the wrong device, switch cards, if the speaker is swapped, switch the pan(channel).

do you have more than one sound card in pactl list sinks? What does pactl list sinks | grep "node.name" return, that should show if you have multiple cards.

[jhalves]

I have 3 audio cards:

• hdmi display monitor audio card for display monitor speakers that i setup only for crewchief. No other sound comes out of it except crewchief.

• external usb audio card connected to my sound system amplifier where the ac game sounds comes out. No other sound comes out of it.

• motherboard sound card connected to another amplifier where i connect 2 transducers/bass speakers (one under my chair and other under my pedals). Only the sinewaves generated by monocoque are coming out of this transducers. This sinewaves are not eared in any other speakers.

The hardware setup is perfect. I have been using it with AC/simhub/crewchief for years on windows and always worked without flaws. Its also well routed here and working fine in linux (ac/monocoque/crewchief)

Compiled the new monocoque release. No errors :) Thank you for updating it ;)

Gears work perfect. The problem is with engine frequencies. At low rpms works great. The rumbling on chair/pedals is perfect after some volume adjustments on the channels. Just rumbling. When rpms go higher the rumbling disapears and its replaced by a sound. Its like the frequency changes acording to rpms. if this how you set it then its working as it should.

In simhub the rpms dont change the frequency of the sinewaves but the intensity (volume). I can feel more or less rumbling according to the different rpms but the frequency dont change (if it the does its very little and i dont notice).

The reason why it was feeling like on/off was that i was filtering higher frequencies with a equalizer so no sound ever comes out of transducers. Turning off the equalizer i could see what was happening and its just replacing the rumbling on low frequencies with the sound on high frequencies.

Im suprised nobody else mention this to you. I think you should associate the rpms with intensity and not frequencies or if you do, make the frequencies field shorter so we can get the rumbling on higher rpms too. I tryed to play with the frequencies on config but didnt notice any difference.

I still dont get the diameters.config working but maybe thats because my pedals are very old and the potentiometers are spiking a little sometimes and that may cause monocoque to detect inputs on pedals. I will clean potentiometers tomorow and try it again.

I will keep giving my feedback and point of view from a very happy simhub user. Made simhub working without any problems on linux but its not detecting shared memory or AC yet. The shared memory structure on AC simhub its exactly the same of AC Crewchief (according to the python apps they both install on AC) so maybe i will make it work somehow after a lot of try and error :)

I will keep up trying to make monocoque work for my purposes no matter what cause i really love open source projects and i think its really good what you are doing. Also thank you for all your help. Thank you! :) Will report soon :)

[Spacefreak18]

well, i'm glad gear works perfect.

ah yes, that is how i coded the rpms to work, i should have mentioned. I think simhub actually lets you choose both, but i could be mistaken. I actually have config variables set aside to let you choose between frequency modulation and amplitude modulation for lack of a better term, I just didn't implement the amplitude option yet.

thanks for sticking with it, yeah, your feedback is definitely welcome. if you want, i could probably throw together the amplitude modulation fairly quickly. I'm in the middle of a couple other things ( trying to get car proximity data and rewriting the backend to simmonitor to use lvgl).

The shaker stuff took me a while to get working too, I have a 7 channel card and external card for it.

I tried the diameters.config quickly earlier today, and i got it to work even if i deleted my existing diameters.config. You'd have to send a full output of monocoque play -vv for me to debug further. It should be located in $HOME/.config/monocoque/diameters.config .

The only other thing i can think of, but i don't think this is it, is I might have forced it to look for the data from the CrewChief plugin, but I could have sworn that was only for simmonitor. But i'm not sure CrewChief would be working right for you without it. I honestly don't have much error protection around it either, so I'm surprised it decided to just fail silently and not crash everything lol. I can usually get the diameters to set if i just drive out of the pits, accelerate to 70kph, then take my hands and feet off everything.

again, thank you for your feedback and gratitude! any feedback is welcome.
