Dear Trent, Thanks for all the help.
I am using PTAMM and I had compiled it 2-3 weeks back and there was no issue .However now upon compiling I get the following errors: Model3ds.o: In function `PTAMM::Model3DS::_GenerateDisplayList(Lib3dsFile*, bool)': Model3ds.cc:(.text+0x510): undefined reference to `lib3ds_mesh_calculate_vertex_normals' Model3ds.o: In function `PTAMM::Model3DS::_Load()': Model3ds.cc:(.text+0xe88): undefined reference to `lib3ds_file_open' collect2: ld returned 1 exit status make: *** [PTAMM] Error 1 I came across ur forum and added the compile flags but still the problem persists ,I am really stumped because I am not able to get something 2 work which I had in the past ! . Could u pls give me any suggestions which would help me I downloaded the test file which u gave and I got the following output Expecting: 0.065576; Value returned by lib3ds: 0.065576 If the values do not match try compiling lib3ds with the -O0 flag, or with a version of g++ prior to 4.0 which means things r fine .. could u pls help me I would really appreciate it if you could give me ur valuable feedback Kindest Regards Rahul -- Incompatibility with GCC4 optimization https://bugs.launchpad.net/bugs/3711 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
