OpenGL beginner issues

I am trying to compile some OpenGL source code and keep getting errors. I am running RH 7.0 and appear to have all of the libraries. Here are the errors. Could someone please let me know what I am doing wrong. I am about to pull out my last remaining strand of hair. Thanks LEPP OpenGL]$ g++ test.cpp /tmp/cccI2Dbq.o: In function `display(void)'': /tmp/cccI2Dbq.o(.text+0xf): undefined reference to `glClear'' /tmp/cccI2Dbq.o(.text+0x29): undefined reference to `glColor3f'' /tmp/cccI2Dbq.o(.text+0x36): undefined reference to `glBegin'' /tmp/cccI2Dbq.o(.text+0x4d): undefined reference to `glVertex3f'' /tmp/cccI2Dbq.o(.text+0x64): undefined reference to `glVertex3f'' /tmp/cccI2Dbq.o(.text+0x7b): undefined reference to `glVertex3f'' /tmp/cccI2Dbq.o(.text+0x92): undefined reference to `glVertex3f'' /tmp/cccI2Dbq.o(.text+0x9a): undefined reference to `glEnd'' /tmp/cccI2Dbq.o(.text+0x9f): undefined reference to `glFlush'' /tmp/cccI2Dbq.o: In function `init(void)'': /tmp/cccI2Dbq.o(.text+0xb7): undefined reference to `glClearColor'' /tmp/cccI2Dbq.o(.text+0xbf): undefined reference to `glLoadIdentity'' /tmp/cccI2Dbq.o(.text+0xe8): undefined reference to `glOrtho'' /tmp/cccI2Dbq.o: In function `main'': /tmp/cccI2Dbq.o(.text+0x107): undefined reference to `glutInit'' /tmp/cccI2Dbq.o(.text+0x114): undefined reference to `glutInitDisplayMode'' /tmp/cccI2Dbq.o(.text+0x129): undefined reference to `glutInitWindowSize'' /tmp/cccI2Dbq.o(.text+0x138): undefined reference to `glutInitWindowPosition'' /tmp/cccI2Dbq.o(.text+0x148): undefined reference to `glutCreateWindow'' /tmp/cccI2Dbq.o(.text+0x15d): undefined reference to `glutDisplayFunc'' /tmp/cccI2Dbq.o(.text+0x165): undefined reference to `glutMainLoop''
