I’m trying yo make an OpenGl ES 1.1 project in Tizen SDK. The thing is I don’t whant to use the  #include <FGraphicsOpengl.h> from Tizen. 

I want to use the the gl.h and glext.h from Khronos site. 

My sources compile just fine, but at the Link stage I get an error like this:

xxxlib220.o: In function `~PDGL’:
Debug-Tizen-Emulator/../src2/PDGL.cpp:568: undefined reference to `glDeleteTextures’

What could be the cause ?
