--- Comment #10 from Tobias Burnus <burnus at gcc dot gnu.org> 2012-11-27 09:32:55 UTC --- (In reply to comment #6) > Created attachment 28779 [details] > Patch to use libbacktrace I have to apply the following patch on your patch in order to be able to compile it. ("MULTIBUILDTOP" is empty here and the library is not in "/libbacktrace".) --- libgfortran-backtrace-pr54572.diff.orig 2012-11-27 10:09:13 +0100 +++ libgfortran-backtrace-pr54572.diff 2012-11-27 10:12:05 +0100 @@ -51 +51 @@ index abc23cd..dd325bd 100644 -+ -I$(MULTIBUILDTOP)/../libbacktrace \ ++ -I$(MULTIBUILDTOP)../libbacktrace \ Additionally, I wonder whether one should have: --- a/Makefile.def +++ b/Makefile.def languages = { language=fortran; gcc-check-target=check-fortran; lib-check-target=check-target-libquadmath; + lib-check-target=check-target-libbacktrace; lib-check-target=check-target-libgfortran; }; languages = { language=java; gcc-check-target=check-java; And in the same file, I wonder which of the following two is correct: +dependencies = { module=all-target-libgfortran; on=all-target-libbacktrace; }; or +dependencies = { module=configure-target-libgfortran; on=all-target-libbacktrace; };
