Hello, I also seem to have exactly the same issue but I'm totally confused on how to solve it.I'm using debian testing with GGC 6.2 and GNAT 6.2 and llvm 3.5 for building the latest version of ghdl source.
This is the output from GCC -v gcc -v Using built-in specs.

Any help much appreciated. Would it mean that libgrt needs to be a shared library build with -fPIC or the ada equivalent? Because this is the first time I post in this list and I'm not very familiar, is there an easy way to search past entries on this list? Thank you, Stelios
