Hi Brad,
I am glad it was something this simple (even though with far-reaching
consequences)! It is not something I could have found out myself.
Regards,
Arjen

for the PLplot project (http://plplot.sf.net) I have tried to use
the Visual Studio 2008 generator in combination with Intel Fortran
(version 11.1). Generating the solution and the project files
works fine, but when I try to build it all, I get error messages
about various symbols being doubly defined (in libcmt.lib - __aenvptr,
__wenvptr, ___error_mode and ___app_type) and also a missing symbol
in libifcoremt.lib (_MAIN__).
These are system libraries that get included automatically during the
link step.
If I use the NMake Makefiles generator, however, all goes well.
I can reproduce this with VS 2008 and Intel 11.1 in 32-bit mode:
LIBCMT.lib(dllcrt0.obj) : error LNK2005: __aenvptr already defined in
LIBCMT.lib(crt0.obj)
LIBCMT.lib(dllcrt0.obj) : error LNK2005: __wenvptr already defined in
LIBCMT.lib(crt0.obj)
LIBCMT.lib(dllcrt0.obj) : error LNK2005: ___error_mode already defined in
LIBCMT.lib(crt0.obj)
LIBCMT.lib(dllcrt0.obj) : error LNK2005: ___app_type already defined in
LIBCMT.lib(crt0.obj)
Note that one comes from "dllcrt0.obj" and the other from "crt0.obj".
The build is mixing static and shared runtime libraries.
It looks like the Platform/Windows-ifort.cmake module is not getting
loaded for this generator. This is due to a dumb bug in the language
information files. I've pushed out a fix:
