    Now I tried to install epics using mingw. (success once using Visual Stdio, but then failed, so i want to use msys2 ).

    But  the error "ccl.obj e_flex.exe "still came out.

    I did as https://docs.epics-controls.org/projects/how-tos/en/latest/getting-started/installation-windows-msys2.html.

   1) pacman -S mingw-w64-x86_64-toolchain

   2) export EPICS_HOST_ARCH=windows-x64-mingw

3) others and "make"

4) I uninstalled VS and reboot, nothing changed.

Output of make:

This line shows that your EPICS_HOST_ARCH is still set to windows-x64, which is for the Microsoft compiler.

You need to set ist to use the MinGW compiler, like you were showing further above. This setting must be done in the shell that you run 'make' from.

There is no need to uninstall compilers that you don't use. (My Windows laptop has 4 compiler chains installed.) Setting EPICS_HOST_ARCH correctly and running the compiler settings batch file (in case of the Microsoft compiler) is good enough.
