Compiler Problems

Question

Let me start from the beginning.
I was using MSYS to do a meson build, and it started to compile fine (it was interupted by missing Directx-headers).
Later, when I tried the build again, it halted with a compiling error about not finding mspdb140.dll.
I checked to find the file resided in three places in C:\Program Files (x86)\Microsoft Visual Studio 14.0\
...Common7\IDE
...VC\bin
...VC\bin\amd64

I already have C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE in my path.

Anyway the problem was annoying me, since I couldn't figure out why I was suddenly getting compiler error, even in gcc in the MSYS builds, so I did a system restore, as I figured something I did messed things up.

Unfortunately that did not fix the problem MSYS started telling me 'compiler cc cannot compile programs'.
Google didn't help me much with that, since everything seemed Linux related.

I got the idea of trying Visual Studio with meson, and I did find the mesonbuild site useful, and VS gave me more details on the error.
It reported it cannot find mspdb100.dll.
So I put the C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64 in the path (...10.0\VC\bin was already there).

After a reboot, whe I tried the build I started getting

***The application was unable to start correctly (0xc000007b). Click OK to close the application.***

Then

***Microsoft C/C++ Compiler Driver stopped working***

I really don't know what to do at this point.
Is there a way I can fix the compiler issues without having to reinstall any VS?
Does my path environment need cleaning up?
I'm actually having issues with that also. I didn't get any feedback on that.

Edit:
I'll include the log file.
The attachment does not seem to be working.

Hello,

Your best course of action is to ask in the following forum

Answer 2

I haven't been able to find any post buttons on Google Groups, although there appear to be another way. However the problem has been resolved.

Answer 3

With the help of this link, I got an idea to try the vs2015 Native Tools Command Prompt, instead of the 2017, and that solved the problem.
I don't know why, since the 2015 dlls were what could not be found. So I'm stumped.
At least the build made a step forward.
