[Mingw-users] g++ tries to link in msvcrt when building application

[Rajorshi G. <blo...@gm...>]

Hi,
I am facing a strange problem when trying to use MinGW on Windows XP
SP3. In my project I am compiling various C and C++ files and finally
linking them to create the final executable. The compilation goes
smoothly but I have not been able to link the object files
successfully. If I use g++ to link I always get the following error:

c:/mingw/bin/../lib/gcc/mingw32/4.6.1/../../../../mingw32/bin/ld.exe:
cannot find -lmsvcrt

I don't know why g++ tries to link in libmsvcrt. I could not find this
library in the MinGW directory even though I did find crtdll.dll. Why
does this happen and is there a work around for it?

If I try to call ld directly I get a whole bunch of unresolved symbols
errors for "new", "delete", "memcpy", etc. I tried linking in all the
libraries that should contain these symbols but that doesn't help. My
command line in my Makefile is:

$(CXX) -o ./a.out  $(LIBGCC) $(OFILE_DIR)/*

where LIBGCC = -L/mingw/lib/gcc/mingw32/4.6.1/  -L/mingw/lib/
-lcrtdll -lstdc++ -lgcc -lgcc_eh

The errors are of the form:

InputFiles.o:InputFiles.cpp:(.text+0x78): undefined reference to
`operator delete(void*)'
InputFiles.o:InputFiles.cpp:(.text+0xc8): undefined reference to `strcmp'
InputFiles.o:InputFiles.cpp:(.text+0x12c): undefined reference to
`operator delete(void*)'
InputFiles.o:InputFiles.cpp:(.text+0x144): undefined reference to
`std::__throw_bad_alloc()'
InputFiles.o:InputFiles.cpp:(.text+0x14f): undefined reference to
`operator new(unsigned int)'
InputFiles.o:InputFiles.cpp:(.text+0x17f): undefined reference to `memmove'
InputFiles.o:InputFiles.cpp:(.text+0x1d3): undefined reference to `strncmp'

I have updated MinGW to the latest version using "mingw-get update
<package-names>". I have installed almost all of of the packages. I
have the latest Windows SDK installed.

I could not find another thread which discusses this problem. Any help
will be much appreciated.
