Build command fails on Ubuntu Linux

[patham9]

While apt-get install stalin works, building from source on Ubuntu does not:

^^^^Starting command^^^^
./setjmp_test
This appears to be a X86_64 running LINUX
Stack appears to grow down, which is the default.
A good guess for STACKBOTTOM on this machine is 0x7fffef6d9000.
Note that this may vary between machines of ostensibly
the same architecture (e.g. Sun 3/50s and 3/80s).
On many machines the value is not fixed.
A good guess for ALIGNMENT on this machine is 8.
Generic mark_regs code may work
./gctest
Segfault at 0x0
Unexpected bus error or segmentation fault
Makefile:605: recipe for target 'KandRtest' failed
make: *** [KandRtest] Aborted
Cannot (yet) run Stalin on this architecture

I am probably very late to this but you can actually get past this error and make the executable for your architecture here is how i did that:

1. Added the -std=gnu89 flag to the gc-Makefile.sed make sure to just add it to the CFLAGS after the pipe.
2. cd into include there will be a script called stalin-architecture-name if you run it, it will return unknown which is causing the "Cannot (yet) run Stalin on this architecture". edit it and add copy a previous command like i[3456]86 echo"IA32" to x86_64 echo "arch-amd64" so that the the script now return arch-amd64.
3. if you have a working stalin executable you can make the arch-amd64.c file by first running make stalin-architecture which will make an executable in your current dir now if you run /.stalin-architecture arch-amd64, now it will output the values for your current architecture copy them and paste them in the stalin.architecutres in the include folder.
4. now make the entry for arch-amd64 into the makefile just copy an already existing entry for an arch like IA32 and replace the IA32 related entries to arch-amd64 now run make stalin-arch-amd64.c if everything went fine it will create a stalin-arch-amd64.c into your current dir now just run build and it will make stalin for your current arch from source.
5. if by chance you already dont have a working stalin available go to the ubuntu packages search for stalin they already have a pre-built amd64.c copy that into your source dir and run build hopefully this helps on debian.

Sadly i am not on debian and i tried to use their amd64.c prebuilt source file for arch linux i was able to compile stalin but i failed the ./gctest and when i run stalin i just get zsh: segmentation fault (core dumped) ./stalin
can anyone help me on arch linux.

Please file a Debian bug (bugs.debian.org) so this doesn't fall between the cracks.

I'll try to have a look at it. Patches welcome!

Can i file a debian bug report if i am not on debian. building from source on arch is giving me the problem i think it is because the ./gctest fails i have tried running the ./gctest in gdb an i get this:

Program received signal SIGSEGV, Segmentation fault.

I don't really know what to do next from here.

Can i file a debian bug report if i am not on debian. building from source on arch is giving me the problem

Well, you can. Whether you should is another question.
