Test on Mac OSX 10.9

[sincebelieve]

Hi there, I just test the project on Mac OSX 10.9, it works very well.

The only problem is that tex.pool is not found under tex/, maybe it should be moved from web/ to tex/, otherwise the program utters:

$ ./a.out test.tex 
! I can't read tex.pool.

I want to port this to iOS and Android so that I can compile TeX scripts to get some images of formula. So I need to convert the .dvi files to .png or .svg, I'm currently investigating dvisvgm and dvipng, do you know any other better options?

Thanks.

On iOS at least, I have these Copy build steps; note the second one:

Perhaps I should mention this in the README.

In the source tree, tex.pool it is in the web folder because it is one of the source files manipulated by the tex.sh script.

Of course, in your app you can place the files wherever you need. You don’t even need to use the ones I supplied. In fact, if you plan on using more than plainTeX you will need more than I provide.

I am eventually planning on writing a .dvi parser that produces .pdf files. But that may be a while…

Be aware that the projects you mention are GPL’d and LGPL’d respectively. dvisvgm, being under the GPL, cannot be used in an App Store app. dvipng, being under the LGPL, requires that users be able to upgrade the version of dvipng that is linked to your app. Since iOS doesn’t allow .dylib files, and Code Signing wouldn’t allow a user to run a modified binary anyway, you will have to make the source of your app available to all of your users. And that’s assuming the LGPL doesn’t have the same restriction listed in the link above preventing you from releasing the app (via the App Store) in the first place.

“I’m not a lawyer” and all that, but that’s my understanding.

Thanks for the information, I'm a newbie in this industry, I think I need a more serious survey on software licences.

I successfully port TeX– to Android, I think people may be interested, here is the configuration for cross-compiling (on Mac OSX 10.9):

In Android.mk:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := tex-engine      # => libtex-engine.so
LOCAL_SRC_FILES := tex-engine.cpp
LOCAL_CPPFLAGS  += -std=c++11

include $(BUILD_SHARED_LIBRARY)

In Application.mk:

NDK_TOOLCHAIN_VERSION := clang
APP_STL := gnustl_static
