Question
Problems linking MFC with an external C lib
Using the AppWiz in VC++ 4.2 I have generated program using only the default settings.
(This program links and runs fine)
The only change I made to the default project setting was to add the name of the external lib to the link section of the project settings.
When I try to use a function from this external library I get the following link errors:
Linking...
LIBC.lib(crt0dat.obj) : error LNK2005: _exit already defined in msvcrtd.lib(MSVCRTD.dll)
LIBC.lib(crt0dat.obj) : error LNK2005: __exit already defined in msvcrtd.lib(MSVCRTD.dll)
.
.
.
LINK : warning LNK4098: defaultlib "LIBC" conflicts with use of other libs; use /NODEFAULTLIB:library
If I change project settings to ignore libc.lib I get the following link errors:
Linking...
protoolkit.lib(apfutil.obj
.
.
protoolkit.lib(session.obj
.
protoolkit.lib(genutil1.ob
.
protoolkit.lib(ctsysutil.o
protoolkit.lib(windows_32.
protoolkit.lib(genutil1.ob
protoolkit.lib(cu_appid.ob
protoolkit.lib(rpctool.obj
Debug/test1.exe : fatal error LNK1120: 4 unresolved externals
Error executing link.exe.
test1.exe - 27 error(s), 0 warning(s)
The external lib works fine if I use a console app with no MFC calls.
The vender (PTC) says this should work fine but has not tried it??????
Any ideas?
Eric
