willing to test gcc42 on Mac OS X 10.3.9, PowerBook G4

[yaseppochi (Stephen J. Turnbull)]

If you have anything specific I should look for, please let me know. Here's progress to date

I've uncommented the darwin 7 variant in the Portfile. This gives the following kind of error in the build:

if [ x"" != x ]; then \

Warning: the following items did not execute (for gcc42): com.apple.build Error: Status 1 encountered during processing.

This error will occur in several places and stages of the build, depending on which of the CFLAGS variables below are used; the above is just the most recent example (which occurred with only XCFLAGS set of the three). The following spec for darwin7 variant led to a successful build:

# hope springs eternal! uncommented by sjt # untested on darwin 7 platform darwin 7 {

depends_build port:odcctools patch {

reinplace "s|/usr/bin/libtool|${prefix}/bin/odlibtool|g" \

${workpath}/gcc-${version}/gcc/config/darwin.h

} configure.args-append --with-as=${prefix}/bin/odas \

--with-ld=${prefix}/bin/odld \ --with-ar=${prefix}/bin/odar

# added by sjt build.args-append XCFLAGS=-force_cpusubtype_ALL configure.env CFLAGS=-force_cpusubtype_ALL \

BOOT_CFLAGS="-g -O2 -force_cpusubtype_ALL"

}

The -force_cpusubtype_ALL may not be omitted from any of the three *CFLAGS variables. Of course it's possible (likely?) that there's a better way to achieve this end, but those are the variables I could find that seemed to be more or less appropriate.
