Subject: MinGW now needs to link to libquadmath.a
Download (untitled) / with headers
text/plain 845b
Hi, With the latest mingw64-runtime (version 4) libgfortran.a contains some symbols that are resolved by libquadmath.a. Hence this patch to F77.pm in ExtUtils-F77-1.17_01: ############################### --- F77.pm_orig 2015-05-18 20:00:56 +1000 +++ F77.pm 2015-05-18 20:03:29 +1000 @@ -122,7 +122,7 @@ } else { $dir = "/usr/local/lib"; } - return( "-L$dir -L/usr/lib -lgfortran -lm" ); + return( "-L$dir -L/usr/lib -lgfortran -lquadmath -lm" ); }; $F77config{MinGW}{G77}{Trail_} = 1; ############################### Note that if libquadmath.a is non-locatable, the link is automatically removed by EU::MM - so this change will not break existing builds that use the older runtime (and therefore don't need to find and link to libquadmath.a). Without this patch PDL::Slatec will fail to build. Cheers, Rob

Just correcting that it's actually the version of gcc (ie 4.9.2), not the version of the runtime that's making the difference. (Same action still required.) Cheers, Rob

Thanks for the patch, Rob. I've been added as co-maintainer for EU::F77 so I'll put that in and push an official release soon.
