So allow me > some time to come up with some patches that don't look like a bad hack :-) I think I managed not send a snarky post saying you could do all the fiddling at the translate/gcc/dist.sh script level, which would have the saving grace of not requiring someone to verify your changes don't affect any other ghdl build method, but from Tristan's post he is apparently volunteering. The big question is whether or not a cross compile target can be generalized, and it likely can be, EXE suffixes aside. And I take it you are aware libgrt.a is GPLv2? The implication being distributed executable models are GPL'd. There's a ghdl-discuss thread from April 28, 2010, where Tristan says he didn't anticipate someone delivering executable models, maybe he'll bend to an LGPL. _______________________________________________ Ghdl-discuss mailing list Ghdl-discuss@gna.org https://mail.gna.org/listinfo/ghdl-discuss
