c compilation error: multiply defined symbols

Dear all

When I add some externals needed by inline C code to my project,
freezing fails with:

MSVCRT.lib(MSVCR90.dll) : error LNK2005: _free already defined in

If I manually add "-NODEFAULTLIB:MSVCRT" to the makefile, I get some
warnings during (manual nmake) compilation but the created binary works.
If I manually add "-NODEFAULTLIB:LIBCMT" to the makefile, I get no
warnings during (manual nmake) compilation and the created file works
only in the W_code directory (in other directories, I get an error that
MSVCR89.dll was not found).

Does anyone have insights on what's going wrong and on how to fix it? I
have no clue what's pulling in what...


Thanks

I now set "Omit Default Library Names" to "Yes" for the external
library. This way, EiffelStudio is able to compile the project as usual
but I get a lot of C compilation warnings like:

antlr3c.lib(antlr3exception.obj) : warning LNK4049: locally defined
symbol _fprintf imported
antlr3c.lib(antlr3basetree.obj) : warning LNK4049: locally defined
symbol _fprintf imported
antlr3c.lib(antlr3lexer.obj) : warning LNK4217: locally defined symbol
_fprintf imported in function _mTokens
antlr3c.lib(antlr3rewritestreams.obj) : warning LNK4049: locally defined
symbol _fprintf imported
antlr3c.lib(antlr3baserecognizer.obj) : warning LNK4049: locally defined
symbol _fprintf imported
antlr3c.lib(antlr3basetreeadaptor.obj) : warning LNK4049: locally
defined symbol _fprintf imported
antlr3c.lib(antlr3exception.obj) : warning LNK4217: locally defined
symbol ___iob_func imported in function _antlr3ExceptionPrint
antlr3c.lib(antlr3basetree.obj) : warning LNK4049: locally defined
symbol ___iob_func imported
antlr3c.lib(antlr3lexer.obj) : warning LNK4217: locally defined symbol
___iob_func imported in function _mTokens
antlr3c.lib(antlr3rewritestreams.obj) : warning LNK4049: locally defined
symbol ___iob_func imported


Doesn't look exactly clean to me (but at least it works)...

Thanks
Marco

You have to get a version of antlr3c.lib which is compiled with the MT option and
not with the MD option. Or better recompile it yourself with the MT option. Those
warnings could be problematic and I certainly recommend finding a way to fix them.

Manu

Yep, that did the trick. Now everything compiles fine without errors or
warnings.


Thanks a lot
