error #31001: The dll for reading and writing the pdb (for example, mspdb110.dll) could not be found on your path

Hi everyone,

I recently upgraded my Intel Composer version (2016 -> 2017 update 1) and cannot compile my program anymore in 32bit mode. I get this error :

"error #31001: The dll for reading and writing the pdb (for example, mspdb110.dll) could  not be found on your path"

I found this similar topic but in my case it works fine in 64bit and crash in 32bit. The compilation crash in command line and in Visual Studio.

My config: Win7 (64bit), Visual Studio 2013, Platform Toolset: Intel C++ Compiler 17.0, Base Platform Toolset: V100.

Can someone help me please ?

Hi, Guix

I think your Base Platform Toolset should be v120 for Visual Studio 2013. (v100 is for older Visual Studio 2010)

Please also make sure the mspdb120.dll can be found from "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\BIN\" installation path.

Hope this helps.

Thank you.

Thx for your reply Yolanda.

Actually, it works fine when setting the Base Platform Toolset to v110 or v120. But I am stuck with v100 because of dependencies on old thirdparties and I cannot switch my program to a newer toolset.

I tried to add "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64" in the PATH (locations of mspdb100.dll). Now the compilation 32bit is OK but it crash at link time with :

"error MSB6006: "xilink.exe" exited with code -1073741701"

It still works fine in 64bit with v100 (or v110 or v120) Base Platform Toolset. What is wrong with the 32bit mode ?

Any other advice ?

Hi, Guix

The path "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64" is for 64bits binary and dlls instead of 32bits.

Could you find the x86 mspdb100.dll from "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin"?

Thanks.

Hi Yolanda,

I reinstalled (two times) VS 10 and then Composer 2017 Update 1. At "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin" there is two folders: "amd64" and "x86_amd64". I find mspdb100.dll in "amd64"  but not in  "x86_amd64". I also find mspdb100.dll at "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE", I do not know if it is a 32bit or 64bit dll. 

Please note that everything works fine if I switch back to Composer 2016.

I noticed that during the installation of Composer 2017 Update 1 there is no checkbox for Visual Studio 2010 at the "Choose Integration Target" step. Is Composer still compatible with VS 2010 ?

Thanks,

Guix

The release notes should confirm if vs2010 support was dropped. Historically, Intel compilers have supported at most 3 vs versions.

Oh no... you are right Tim. Page 7 of the release note : "Support removed for Visual Studio 2010"

Does the mspdb*.dll really needed for the compilation ? Is there a workaround ? 

It is ok with 64bit, I am pretty sure that there is a little trick for the 32bit mode.

pdb comes into play only when you build with a debug option (e.g. -debug:inline-debug-info, or full debug build).  Even then, if there is a problem, it will only prevent debug symbols from appearing to implement debugging and profiling; it won't affect execution otherwise.
