I seem to keep getting errors on compilemfcwg32d.lib(CHGRID.OBJ) : error LNK2001: unresolved external symbol "public: static struct CRuntimeClass  CWnd::classCWnd" (?classCWnd@CWnd@@2UCRuntimeClass@@A)
mfcwg32d.lib(CHCOMB.OBJ) : error LNK2001: unresolved external symbol "public: static struct CRuntimeClass  CWnd::classCWnd" (?classCWnd@CWnd@@2UCRuntimeClass@@A)
mfcwg32d.lib(CHLIST.OBJ) : error LNK2001: unresolved external symbol "public: static struct CRuntimeClass  CWnd::classCWnd" (?classCWnd@CWnd@@2UCRuntimeClass@@A)

its not my .lib, but i was wondering how to make the compiler ignore/fix these....Under vs97. i have all the include files .h, but not one single .cpp file eg chlist.cpp/chgrid.cpp, well you get it. Can i extract the .obj from the .lib?, than the .cpp files, or am i looking in the wrong direction?

ive been banging my head up against the wall for awhile. tried lib.exe, shows the .obj files
tried extracing /out but no avail.
/nologo /MT /W3 /GR /GX /O2 /I ".\include" /I ".\widgets\include" /D "WIN32" /D "NDEBUG" /D "_WINDOWS" /D "_MBCS" /Fp".\ace.rel/Ace.pch" /Yu"stdafx.H" /Fo".\ace.rel/" /Fd".\ace.rel/" /FD /c

some idea is better than nothing...can you plz advise me wht to do?

thanks in advance

According to msdn help
there are two reasons this error occurs: what the code asks for doesn’t exist (the symbol is spelled incorrectly or uses the wrong case, for example), or the code asks for the wrong thing (you are using mixed versions of the libraries?some from one version of the product, others from another version).

you must have the library file (.lib )file for each header file.Because it will look for the functions in .lib file wile linking .if u have the .c or .cpp implementation file compiler will generate the .lib file .
