Hello @Issraa, From the looks of it seems that you have built and installed the SystemC library in the source directory. Usually from a developer perspective I keep the source and installation location separate. Below is a representative directory layout that I follow for my development practices. # Sample layout of the SystemC sources and installation paths $ ls systemc-2.3.3 #< Unzipped from below tarball sources for SystemC library systemc-2.3.3.tar.gz
