This one is strange. On i686-mingw, compiling gfortran fails with: ../../../gcc/libgfortran/generated/exp_c8.c:38: error: conflicting types for 'cabs' /mingw/include/math.h:223: error: previous declaration of 'cabs' was here make[2]: *** [exp_c8.lo] Error 1 make[2]: Leaving directory `/home/coudert/ibin/i686-pc-mingw32/libgfortran' make[1]: *** [all] Error 2
I guess, somewhere in the configure process, the presence of cabs() in math.h was not detected. This is not specific to i686-mingw, since the same thing happens on mips-sgi-irix6.5 (which I reported as comment #7 in PR15266). So, I submit a new PR (hope "component=bootstrap" was the right choice, not sure) so that GNU build utils gurus can get this fixed. I am ready to give any extra information needed, but I don't know what may be useful at that point. PS: configure was a simple ../gcc/configure --prefix=/mingw --enable-languages=c,f95 -- Summary: libgfortran doesn't build -- configure doesn't handle cabs() well Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P2 Component: bootstrap AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: coudert at clipper dot ens dot fr CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19481
