I'm having some difficulty linking OSdemo32 [Mesa Demo] on MSYS2/MinGW. Basically, some functions are not included in libGLU.a as the error returned is undefined reference to __imp_glu... It's strange because these functions exist in the libGLU source and I am building and using a static libGLU library (versus a .dll which could have some dll import issues as explained at the bottom).
Here is what the last bit of linking trace looks like: * building Mesa demo... g++ -DHAVE_FREEGLUT -DFREEGLUT_STATIC -O3 -I/opt/osmesa/include -I../../src/util -include /opt/osmesa/include/GL/gl.h -include /opt/osmesa/include/GL/glu.h -include /opt/osmesa/include/GL/freeglut.h -o osdemo32 osdemo32.c -L/opt/osmesa/lib -losmesa -lfreeglut -lGLU -lz -LC:\Users\Trevor\Projects\osmesa-install\build\install\llvm/lib -lLLVMX86Disassembler -lLLVMX86AsmParser -lLLVMX86CodeGen -lLLVMGlobalISel -lLLVMSelectionDAG -lLLVMAsmPrinter -lLLVMDebugInfoCodeView -lLLVMDebugInfoMSF -lLLVMCodeGen -lLLVMScalarOpts -lLLVMInstCombine -lLLVMTransformUtils -lLLVMBitWriter -lLLVMX86Desc -lLLVMMCDisassembler -lLLVMX86Info -lLLVMX86AsmPrinter -lLLVMX86Utils -lLLVMMCJIT -lLLVMExecutionEngine -lLLVMTarget -lLLVMAnalysis -lLLVMProfileData -lLLVMRuntimeDyld -lLLVMObject -lLLVMMCParser -lLLVMBitReader -lLLVMMC -lLLVMCore -lLLVMSupport -lLLVMDemangle -lpsapi -lshell32 -lole32 -luuid C:\msys64\tmp\cc4gd4Lj.o:osdemo32.c:(.text.startup+0xe1): undefined reference to `__imp_gluNewQuadric' C:\msys64\tmp\cc4gd4Lj.o:osdemo32.c:(.text.startup+0x347): undefined reference to `__imp_gluCylinder' C:\msys64\tmp\cc4gd4Lj.o:osdemo32.c:(.text.startup+0x3a7): undefined reference to `__imp_gluSphere' C:\msys64\tmp\cc4gd4Lj.o:osdemo32.c:(.text.startup+0x3bf): undefined reference to `__imp_gluDeleteQuadric' collect2.exe: error: ld returned 1 exit status I had numerous 'redeclared without dllimport attribute: previous dllimport ignored [-Wattributes]' warnings while building libGLU but as I am using a static lib, I imagine this should not be related to my issue. However, this situation could indeed cause functions declared without dllimport attributes to not export to the compiled [dynamic] library. Thanks. Cheers,
