[RPI][X11] Compile failure

rubenverhoef commented 5 years ago

When compiling on my RPI 3b+ with X11 mode i get this output:

When removing the line #include "GL/gl.h" from x11/gl_common.h i will get:

any ideas?

@rubenverhoef Sorry for the slow reply, life's been a 'bit' busy the last few weeks. It looks like there might be a bug in the Makefile for x11

If you edit x11/Makefile.include and add a - before std=c99 this might fix the issue you're having. ie. LDFLAGS+=-std=c99 -lm -lEGL -lGLESv2 -lX11

@meekys No problem we all have normal lifes to live

Stupid that i not saw it, i was misled by the second = i think. The first fix is also needed for me to compile the software. It is working fine after that. So close #12

I also added some changes to run it fullscreen on my pi, like the not X11 version does: https://github.com/rubenverhoef/cam_overlay/commit/06f2f112747177551ba62e54190424592b5b91b4
