Hey guys,
So I have compiled my first home-written static library (named PixGUI) that happens to call OpenGL functions. However, I noticed that when compiling (using MinGWs GCC with Code::Blocks project set to "static library") it doesn't matter whether I supply the linker with libopengl32.a or not, it simply compiles each time.
However, when I link PixGUI to another project, i.e. Pixlings, and try to compile that, it gives me these errors:
||=== Pixlings, Release ===|
..\PixGUI\lib\libPixGUI.a(button.o):button.cpp:(.text+0xc1)||undefined reference to `glColor3fv@4'|
..\PixGUI\lib\libPixGUI.a(button.o):button.cpp:(.text+0xea)||undefined reference to `glRectf@16'|
||=== Build finished: 2 errors, 0 warnings ===|The build log of libPixGUI.a (without supplying the linker with opengl32, but doesn't matter for undefined references)
