linking errors when having Intel Parallel Studio XE Composer (2013 and 2017 versions), VisualStudio (2010 and 2015 versions)

[gigi_s_]

I have a code base(primary C, with some C++) which has recently been ported to Visual Studio 2015. On the same machine(Windows 10 x64) I have installed both Intel Parallel Studio XE Composer 2013 and 2017(installed because of its support for Visual Studio 2015). Under "C:\Program Files (x86)" I have the corresponding installation folders: "Intel"(2013 version) and "IntelSWTools"(2017 version).

After I open my solution with VS2015 and try to compile one of the projects I get this output:

1>------ Build started: Project: tdvdxf, Configuration: Release Win32 ------
1>libifcoremt.lib(for_diags_intel.obj) : error LNK2019: unresolved external symbol _vsprintf referenced in function _for__io_return
1>libirc.lib(irc_msg_support.obj) : error LNK2001: unresolved external symbol _vsprintf

1>D:\bsw_2015\Out\tdvdxf\Release\tdvdxf.exe : fatal error LNK1120: 4 unresolved externals

If rename "C:\Program Files (x86)\Intel" folder to "C:\Program Files (x86)\Intel_" then everything is ok. If I rename it back to "C:\Program Files (x86)\Intel", the problem comes back.It looks like if Intel Parallel Studio XE Composer 2013 is missing, than I can compile in Visual Studio 2015.

At the same time, I need to build the same code base with visual studio 2010 and for this I need Intel Parallel Studio XE Composer 2013 and its folder (C:\Program Files (x86)\Intel)

Any idea on this ?

Thank you!

First, you need to make sure that both your C project and Fortran project have selected the same set of run-time libraries to link against. From the error messages I see that your Fortran project specifies the static libraries, but MSVC defaults to DLL libraries and these must be the same.

In Fortran, it's Libraries > Use Run-Time Library. Multithreaded vs. Multithread DLL, In C, it's under Code Generation. Make these consistent and rebuild.

The next thing is that you have to configure C++ to link to Fortran libraries, and it sounds as if you haven't done this correctly. See https://software.intel.com/en-us/articles/configuring-visual-studio-for-mixed-language-applications

Let us know if this helps

Hi Steve,

Thank you for your answer. Indeed to path used for linking Fortran libraries(within the VisualStudio2015 projects) was not configured correctly.

It was: $(IFORT_COMPILER14)compiler\lib\ia32\

I have changed it to: $(IFORT_COMPILER17)compiler\lib\ia32\      and everything builds ok now.

Thank you.
