Hi all,
I recently updated both Eclipse to CDT 8.1 and MinGW GCC. Doing that, I deleted the old files of the previous GCC installation. Eclipse recognised the new version of GCC but it also keeps in the old projects the inclusion directories of the previous GCC version, as showed in the screenshot. Is there some way to fix that?

Regards
- Mickey

Project Properties->C/C++ build->Discovery options
click the button "Clear discovered entries" (might be necessary for C and C++ and different build_configs)

Hi, the issue came back. At this time I have two versions of gcc installed: 4.6.3 and 4.7.2. Globally I switched to gcc-4.7.3. However includes of the previous version of GCC are still present and Eclipse points to the old version /usr/lib64/gcc/x86_64-pc-linux-gnu/4.6.3, while it should be /usr/lib64/gcc/x86_64-pc-linux-gnu/4.7.2/. In this case the trick to clear the discovered entries does not work.

Any solution?

regards
-Mickey

C/C++ build->Discovery options is deprecated (see notice at the bottom of this preference page). You should go to
Project Properties->C/C++ General->Preprocessor Includes

Here you can select the correct compiler version.
