Hi GCC, This is Daniel. I use fedora 29 and have install gcc-8.2.0 into the system. However, I still cannot see GCC on the list when I do "module av". I have added the path of the gcc directory into .bashrc as follows. However, nothing changes. "export PATH=$PATH:/..." "export LD_LIBRARY_PATH=$PATH:/..." Could you tell me what should I do after installation to link gcc to the system? Thanks, Daniel
