Hello, we try to compile a cutting software named Salmon with Cygwin. All the source code files compile to .o object files. But when the linker try to build the binary, there're many openGL errors.
This is the command: g++ -o out-glut/salmon out-glut/adjacency.o out-glut/assemble-matrix.o out-glut/big-vector.o out-glut/bounding.o ... lots of object files ... out-glut/wx-salmon.o -lXi -lXt -lICE -lXext -lXmu -lSM -lX11 -L/usr/X11R6/lib -L/lib/w32api -lglut -lopengl32 -lm This procudes lots of errors: out-glut/closest-vertex-selector-visualization.o: In function

worked.
