Hi, I'm quite new to linux and am facing a few problems while compiling a program in C which uses OpenGL. I have installed Red Hat Enterprise Linux 5 and freeglut was installed as part of the linux installation. ps3.c: In function 'initGL': ps3.c:66: error: 'GL_COLOR_BUFFER_BIT' undeclared (first use in this function) ps3.c:66: error: (Each undeclared identifier is reported only once ps3.c:66: error: for each function it appears in.) ps3.c: In function 'mouse': ps3.c:262: error: 'GLUT_DOWN' undeclared (first use in this function) ps3.c:279: error: 'GLUT_UP' undeclared (first use in this function) ps3.c:297: error: 'GLdouble' undeclared (first use in this function) ps3.c:297: error: expected ')' before 'X' ps3.c:299: error: 'GL_SELECT' undeclared (first use in this function) ps3.c:301: error: 'GL_PROJECTION' undeclared (first use in this function) ps3.c: In function 'keyboard': ps3.c:396: error: 'GL_MODELVIEW' undeclared (first use in this function) ps3.c:397: error: 'GL_MODELVIEW_MATRIX' undeclared (first use in this function) ps3.c:405: error: 'GL_PROJECTION' undeclared (first use in this function) ps3.c: In function 'drawLine': ps3.c:440: error: 'GL_LINES' undeclared (first use in this function) ps3.c: In function 'glowVertex': ps3.c:492: error: 'GL_COLOR_LOGIC_OP' undeclared (first use in this function) ps3.c:493: error: 'GL_XOR' undeclared (first use in this function) ps3.c:496: error: 'GL_POINTS' undeclared (first use in this function) ps3.c: In function 'glowEdge': ps3.c:519: error: 'GL_COLOR_LOGIC_OP' undeclared (first use in this function) ps3.c:520: error: 'GL_XOR' undeclared (first use in this function) ps3.c:524: error: 'GL_LINES' undeclared (first use in this function) ps3.c:531: error: 'GL_POINTS' undeclared (first use in this function) ps3.c: In function 'drawRect': ps3.c:596: error: 'GLUT_DOWN' undeclared (first use in this function) ps3.c:597: error: 'GL_COLOR_BUFFER_BIT' undeclared (first use in this function) ps3.c: In function 'reshape': ps3.c:647: error: 'GL_PROJECTION' undeclared (first use in this function) ps3.c:652: error: 'GL_MODELVIEW' undeclared (first use in this function) ps3.c: In function 'visibility': ps3.c:664: error: 'GLUT_VISIBLE' undeclared (first use in this function) ps3.c: In function 'display': ps3.c:679: error: 'GL_COLOR_BUFFER_BIT' undeclared (first use in this function) ps3.c:687: error: expected ';' before 'drawRect' ps3.c:691: error: expected ';' before 'break' ps3.c: In function 'main': ps3.c:712: error: 'GLUT_DOUBLE' undeclared (first use in this function) ps3.c:712: error: 'GLUT_RGB' undeclared (first use in this function) make: *** [ps3.o] Error 1 Please find attached 'sample.tar.gz'. It contains the following- - C program which I'm trying to compile - Makefile - header file Have I missed a step or two after the installation ? Something like configuring the path etc. If so then please let me know of the same. Any idea on which header file to use in case of freeglut ? Is it freeglut.h ? Though I couldn't find it on my linux box. Regards, Arun A K
