My workaround was to edit the 'Path' env variable in one of the temp files generated by bjam (b2_msvc_14.0_vcvarsall_amd64.cmd in your temp

I encountered the same problem with VC14 RTM on my VM. This was a clean install of VC14 RTM, there were no CTPs or RCs installed on this machine. I removed the b2_msvc_14.0_vcvarsall*.cmd scripts and ran b2 with address-model=64 to build my tests so that these scripts are re-created from scratch, so it looks like there is a problem with how these scripts are generated by b2.

I found 3 instances of mspdb140.dll on my system in these locations:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64

The last two are for 32 and 64-bit native compilers. The first one, I assume, is for use by IDE. The problem is that the first path is listed in b2_msvc_14.0_vcvarsall_x86_amd64.cmd in the "SET Path=..." line prior to the compiler-specific paths. Removing it from the Path solved the problem.

Could Boost.Build be adjusted so that the cmd files are generated correctly in the first place?

Yes! I've been struggling with this all weekend trying to figure out what was going wrong. I've don multiple re-installs of my VM thinking that I might have gotten something corrupted. Your results seem to match what I was seeing exactly. Tom
