Toolchain "MinGW GCC" is not detected, but this is not true [message #1151939]

Hi,

eclipse CDT tells me that Toolchain "MinGW GCC" is not detected.
but that is not true
the build builds, the indexer indexes, so everything works.
I configure my project with cmake

History: I had mingw installed, but switched to mingw64
I have tried all different PATH variables, folder names, using C:\MinGW with my mingw32, ...
nothing helps
eclipse still tells me that Toolchain "MinGW GCC" is not detected

what can I do?

Have you looked at this?
http://wiki.eclipse.org/CDT/User/FAQ#I_installed_MinGW_toolchain_on_my_PC_but_Eclipse_won.27t_find_it.

The section might be outdated a bit but hopefully it will help you. Don't forget to restart Eclipse if you change your PATH environment variable.

Also, if all fails, you can try using the Cross GCC toolchain. It allows you to specify the path to gcc and a prefix. Say you have C:\MinGW64\bin\x86_64-w64-mingw32-gcc.exe. When you create a new project, you can set:
prefix: x86_64-w64-mingw32-
path: C:\MinGW64\bin

Then in your project properties, C/C++ Build, Settings, Binary Parsers, enable the PE Windows parser so it can see the .exe you build!

Thanks for your hints

I have C:\MingW\bin in my PATH
in there is
c++.exe, g++.exe, ....
i686-w64-mingw32-c++.exe, i686-w64-mingw32-g++.exe, ...
mingw32-make.exe
and so on

generating mingw make files with CMake works, I generate them in a subfolder, than I tell eclipse to run the build there.
I have to spezify the mingw32-make.exe as make command, and everything works.

possible that mingw64 is cross compiling prefix requiring stuff?

do not know mingw64, thought it is a drop in replacement,
mingw has some c++11 issues, example std::to_string is not there.

possible I have to make some more research on this topic.

thanks again
