Summary: build fails when gmp/mpfr already installed Product: gcc Version: 4.5.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other AssignedTo: unassig...@gcc.gnu.org ReportedBy: sl...@blue.cft.edu.pl When gmp/mpfr are already installed _and_ their sources have been unpacked into the gcc source directory, building mpfr fails due to gmp.h not found. I would expect such a scenario when building and using the supplied gmp/mpfr sources is preferred over the installed (system) libraries, which typically are outdated (but cannot be uninstalled due to dependencies). FreeBSD 8.1 i386 the configure command line was ../gcc-4.5.3/configure --prefix=${HOME}/opt/gcc/4.5.3 --enable-languages=c,c++,fortran
