gdc-0.24 fails to build with MacPorts 1.8

[afalquina@…]

The following command:

sudo port -v install gdc

fails with this output:

cc1: error: unrecognized command line option "-arch"

Find attached the rest of the command's output as a text file compressed with bzip2.

When building a non-Apple GCC (as in FSF GCC), you can't use the -arch flags (like in the default archflags).

So you need to do some workaround like the gcc41 port does:

# the generated compiler doesn't accept -arch
if {[info exists build_arch] && ${os.platform} == "darwin"} {
    configure.cc_archflags
    configure.cxx_archflags
    configure.objc_archflags
    configure.pre_args-append --build=${build_arch}-apple-darwin${os.major}
}

Alternatively someone could do a apple-gdc40 port, that would accept the -arch flags and similar...

Or even better make GDC run with gcc-4.2 as well as gcc-4.0, by updating the upstream code for it.

Replying to afb@…:

I have added those lines to the Portfile and after a while I get the following error:

gnumake[2]: i386-apple-darwin10.0.0-ar: No such file or directory

I guess I have missed something, since it is the first time I have ever touched a Portfile...

[afb@…]

Sounds like #21388, probably it needs a AR=ar somewhere like in the configure.env.

[afb@…]

The reason it is needed is that the workaround above sets it up for a GNU-style cross-compilation (--build being different from OS) but then it lacks some matching links for the various compiler/linker commands. It also leads to other things like adding a prefix to all the generated commands (like seen in #22163). The "easiest" would have been to not add that -arch everywhere, but the workaround is to use --program-prefix="" in the configure.

[afalquina@…]

I added --program-prefix="" to configure.args, but the build still failed. Afterwards, I added AR=ar to configure.env, then AS=as, NM=nm, LD=ld as different programs were reported to be missing. Finally it complains about i386-apple-darwin10.0.0-cc. I have not found a way around this.

Markus, can you fix this, please? This prevents gdc from being installed at all on MacPorts 1.8 and later.

[ryandesign@…]

Has duplicate #26442.
