Hello Stefan, While using NESTML with NEST installed from conda, the compiler path needs to be changed in the nest-config file which you can find in your NEST installation directory. You can find the detailed instructions on our docs page here: https://nestml.readthedocs.io/en/latest/installation.html#anaconda-installa… Hope this helps! Regards, Pooja On 27.

Tell CMake where to find the compiler by setting either the environment variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH. I have tried to set CXX variable to one of the compilers I have on the system, but it did not work. I don't know how to set CMAKE_CXX_COMPILER in this context. Maybe someone could give me an advice on that?
