Does anybody use (FTGL) font support?

[rhyskoedijk]

I've noticed that FTGL/font support is not actually possible to enable using the standard build script since libftgl is not check and USE_FTGL is never defined.

If I do manually define USE_FTGL, then the project doesn't compile anymore, which hints to me that nobody must have used this for some time?
e.g. /src/libprojectM/Renderer/Renderer.cpp::draw_stats() has a undefined variable renderTarget which is nowhere in sight.

Checking old issues, I can see that FTGL was once enabled in PR #48 but was then later disabled again in commit 1cecc14. Does anybody know the latest word on this situation?

It's quite possible that it was removed as part of the shader rework and GLES compatibility stuff. Does FTGL work with OpenGL ES?

I'm not 100% sure if I understand what you mean, but I have managed to build FTGL against EGL successfully.

My main stumbling block is that the projectM source code has non-compiling code behind some #ifdef USE_FTGL macros as mentioned above. All the text/font rendering functionality is locked behind these #ifdefs and it seems like this code hasn't been maintained with the rest of the project and almost fallen out of date since it is normally disabled in a standard build.

Just for added context, I'm porting this to the Nintendo Switch. Currently it works fine, but font support is disabled and I therefore can't see the preset name when switching presets. I'd like to try find a way to re-enable font support if possible, but maybe this is not realistic and/or not worth the effort to revive.

My port has some patches to re-enable FTGL but also has to nerf the draw_stats() function due to the non-compiling code I mentioned (see: devkitPro/pacman-packages#120).

Okay, the change to disabling Cg was definitely part of the shader and GLES work. I don't know why FTGL was a part of that but if it still builds with ES and FTGL then that is wonderful.

Rebuild with ftgl is VERY smart design approach moving forward. We can use a new lib if it doesn’t work with gles, but the text based code library needs to operate with unification across all implementations. How do we fix FPS?

ftgl has too much bitrot to operate with windows store
