[FIXED] How to setup jenkins windows slave node to support msys2 mingw shell

Issue

I want to build a program with a jenkins windows 7 node. The program is build using cmake but in the configure stage cmake tells me that there is no g++ compiler. I think this error occurs due to the wrong shell but I don't know how to set the right shell. The documentation says that the first sh file on windows is executed but msys2 needs mingw32.exe as the correct shell.

Solution

There are several ways start MinGW shell:

1. Set env variable with set MSYSTEM=mingw32 or set MSYSTEM=mingw64. Then start msys2_shell.cmd or usr/bin/bash --login.
2. Start msys2_shell.cmd with -mingw32 or -mingw64 arg.
3. Type in MSYS2 source shell <name> where can be: msys, mingw32, mingw64.
4. Install msys2-launcher-git and run mingw32.exe or mingw64.exe
