Can somebody give me some hint how to fix it if it is possible?

Hi Mathias,

I have used Eclipse CDT with msys2 and was able to mark it work correctly. The steps below are for the mingw64 toolchain, settings for an msys2 toolchain are a bit different. Also, I'm using Eclipse Luna (4.4) with latest CDT version.

Here the rough steps I performed from memory (some could be missing, some could be extra, hope they help you):

1. I added to my PATH the folders C:\Gnu\mingw64 and C:\Gnu\usr\bin because if I remember correctly, CDT was complaining that gcc command was not found. This is from I read, not recommended by everyone, not sure why thought.
2. In Eclipse CDT preferences (Windows > Preferences > C/C++ > Build > Environment), set a variable MINGW_HOME to /mingw64 mount point location (in my case, path is C:\Gnu\mingw64).
3. Restart Eclipse. Normally, that should be enough. When starting Eclipse, CDT should discover the mingw64 toolchain.

If that does not work out of the box, there is two places to play with some settings:

• Windows > Preferences > C/C++ > Build > Settings (Discovery Tab)
  You can try to clear entries and reset buttons on the CDT GCC Built-in Compile Settings MinGW.
• Project Properties > C/C++ General > Preprocessor Include Paths, Macros, Etc.
  I providers tab, you can try to disable all providers except CDT GCC Built-in Compile Settings MinGW, CDT User Settings Entries and CDT Manager Build Setting Entries

After each try, rebuild CDT index by right-clicking on project and then select Index > Rebuild.

If it works, it should look something like this (with some differences due to settings of my own project):

Hope this helps

Regards,
Matt

Setting MINGW_HOME to c:\msys64 worked for me. Additionally, I appended the PATH variable to c:\mys64\usr\bin which provided the msys2 binaries setup instead of the mingw64 setup. It wasn't necessary to restart eclipse v4.4.2.
