Next problem. I'm using the latest mercurial snapshot of GHDL with GCC backend. When I run GHDL to elaborate a design, it gives a linker error.

Indeed, my grt.lst file contained only these three lines: @/libgrt.a -L./ -lz After manually modifying grt.lst to add "-lm" and "-ldl", GHDL could elaborate my design just fine. I noticed that the magic to determine GRT_EXTRA_LIB in src/grt/Makefile.inc was changed a few weeks ago. Could there be a problem there? My target architecture is x86_64-linux-gnu.
