Thread: after updates, cant compile OpenGL project :(

i copied current code laptop, overwriting previous code, had binary compiled previous (pre updates)

new code, type make, , undefined reference to..... every glfucntion call in program. errors not indicate libgl.so.1 not found. however, notice in wierd place /usr/lib/i386-linux-gnu/mesa???

, libglu.so.1 in /usr/lib/i386-linux-gnu

pretty these libs in /usr/lib previously

gives?

code:
