BUG: gcc42-4.2.0 build fails while executing ar

[ludwig@…]

My system is an Intel Core Duo running Mac OS X 10.4.9. Xcode is version 2.4.1, port is 1.442.

My attempts to install the gcc42 port fail when the build system tries to create libgcov.a and libgcc.a. The error message is

rm -f ./libgcc.a

gzipped log of failed gcc42 build

[ludwig@…]

Discussing this issue with Boey Maun Suang on macosports-user (​http://lists.macosforge.org/pipermail/macports-users/2007-June/003685.html), we found that the gcc42 port somehow conflicts with the binutils port. (Or more precisely, with the ar included in the binutils port.)

After deactivating the binutils port so that gcc42 could no longer pick up /opt/local/i386-apple-darwin8.9.1/bin/ar, the build of gcc42 succeeded.

Regards

O.k., I've added a bunch of environment variables to the gcc42 port to avoid picking up binutils;

I suppose this would be necessary for the other gcc ports, too -- on the other hand we could also remove (or change prefix) of the binutils port, especially since it seems to be defunct (or not fully functional) - Paul?

(gcc 4.2 picks up the tools in ${prefix}/${arch}-apple-darwin${version}/bin/, not the one in ${prefix}/bin)

[mww@…]

I've tested it: The addition of

configure.env-append    AR_FOR_TARGET=/usr/bin/ar \
                        AS_FOR_TARGET=/usr/bin/as \
                        LD_FOR_TARGET=/usr/bin/ld \
                        NM_FOR_TARGET=/usr/bin/nm \
                        OBJDUMP_FOR_TARGET=/usr/bin/objdump \
                        RANLIB_FOR_TARGET=/usr/bin/ranlib \
                        STRIP_FOR_TARGET=/usr/bin/strip

functions as a workaround to avoid binutils
