I have now Cmake 3.4.3 for Windows (should be useable under MingW as well as bare Windows), but after correcting the plplotf95_ifort.def file I ran into a problem with Tcl:

tclAPI.c

D:\plplot-svn\plplot-git\bindings\tcl\tclAPI.c(792) : warning C4996: '_getcwd': The POSIX name for this item is deprecated. Instead, use the ISO C++ conformant name: _getcwd. See online help for details.

        C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\direct.h(59) : see declaration of '_getcwd'

D:\plplot-svn\plplot-git\bindings\tcl\tclAPI.c(3783) : warning C4101: 'argc' : unreferenced local variable

Stop.

NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\BIN\amd64\nmake.exe"' : return code '0x2'

Stop.

The problem is not the message about _getcwd(), but the linkage of plplotLibDir. I haven't analysed the problem in sufficient detail to really understand what is going and why it worked before, but my current guess - and that is a guess, no more - is that the macros that are defined cause the relevant macro PLDLLIMPEXP_TCLTK_DATA( type ) to be defined as "export" instead of "import".

More to follow.

Regards,

Arjen
