Hi Robert,
have you checked your project settings? I can use it without such a problem.

OCC 5.2 linking problem with Visual C++ 7.1
hi everybody!
trying to link OCC52 to my program with Visual C++ 7.1 i get linker errors like this one:
error LNK2019: unresolved external symbol "void * * theFreeList" (?theFreeList@@3PAPAXA) referenced in function "public: static void __cdecl Standard::Free(void * &)" (?Free@Standard@@SAXAAPAX@Z)
when i rebuild TKernel module i get warnings like this:
NCollection_BaseVector.obj : warning LNK4049: locally defined symbol ?theFreeList@@3PAPAXA (void * * theFreeList) imported
NCollection_IncAllocator.obj : warning LNK4217: locally defined symbol ?theFreeList@@3PAPAXA (void * * theFreeList) imported in function "public: static void * __cdecl Standard::Allocate(int)" (?Allocate@Standard@@SAPAXH@Z)
does anyone know a solution to my problem?
thx a lot,
robert

Thanks Patrik, but everything seems ok there. Can you rebuild TKernel.lib with the warnings (say from FoundationClasses.sln)?
greets,

Hello Robert,
I've got the warnings when I rebuild the TKernel module, but I don't get the error when I linked OCC52 with my application. If you could reproduce you problem with a small application, maybe you could send it to me an I will try to rebuild it.
Good Luck,

Hi, Robert,
I have similar problem when I tried to compile the 07_Viewer3D Sample project provided by OpenCASCADE under C:\OpenCASCADE5.2\samples\standard\Mfc. I have got the following 5 link errors of the same type.
Should be grateful if you could let me know how you resolve this.
Many thanks

Please check your environment variable for Visual C++ (Setting up in VC+ option, With VC++7, select Options from Tools menu, then go to Projects/VC ++ Directories item)
Hi,
I have set the pathname to bin and lib of opencascade. I still got the above problem. Any more suggestions will be welcome.
