I just tried on Ubuntu 18, and I got the exact same result. Build fails with the same error. I added the -fPIC flag, and the build succeeded. Then I tried to debug the firmware with JLink and GDB crashes during init with a SEGFAULT. Just like on Fedora. So I guess, this is a problem with the plug-in itself? Those that have managed to use the plug-in successfully, what is the version of JLinkGDBServer ? Mine is V7.54c.
