Problem compiling a VC++ 6.0 Com in .Net Editor

[Usman]

Hi there

I'm having problem compiling my code. I have a library along with its header
file that I've used in my Com project. On compilation I get this linking
error. Does anyone have any idea how to remove these linker errors. The
problem comes only when I use a class (exists in library) variable in my Com
code.

TestAPP error LNK2019: unresolved external symbol _crc32 referenced in
function "public: unsigned long __thiscall CMyArchive::ReadFile(void
*,unsigned long)" (?ReadFile@CMyArchive@@QAEKPAXK@Z)
TestAPP error LNK2019: unresolved external symbol _deflate referenced in
