Investegate commented 3 years ago

Hey,

please help me with this fault :) I have done everything like in the description.

I get this error if i want to compile it on my RPI 3:

Hi @Investegate

I think you are trying to compile a html file. I assume you did wget https://github.com/matusnovak/rpi-opengl-without-x/blob/master/triangle.c and then run it through GCC? Try wget https://raw.githubusercontent.com/matusnovak/rpi-opengl-without-x/master/triangle.c instead.

Hey @matusnovak

Yes you think correctly! Thank you very much 💯
