Try to port intall gcc47, Error: Dependency 'ld64' not found

Question

Try to install gcc47 on osx 10.6.8 but got the following error:

 sudo port install gcc47
--->  Computing dependencies for gcc47
Error: Dependency 'ld64' not found.
Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>

Did I miss anything?

Answer 1

I think it's still there at /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/devel/ld64 However, the Portfile seems so buggy that port index can't parse it. I installed llvm-3.0 first and then edited the Portfile, commenting out the following lines

#if {![variant_isset llvm29] && ![variant_isset llvm30] && ![variant_isset llvm31]} {
#    default_variants +llvm30
#}

#set llvm_version {}
#variant llvm29 conflicts llvm30 llvm31 description {Use llvm-2.9 for libLTO} {
#    set llvm_version        2.9
#    depends_lib-append      port:llvm-${llvm_version}
#}

#variant llvm30 conflicts llvm29 llvm31 description {Use llvm-3.0 for libLTO} {
set llvm_version        3.0
#    depends_lib-append      port:llvm-${llvm_version}
#}

#variant llvm31 conflicts llvm29 llvm30 description {Use llvm-3.1 for libLTO} {
#    set llvm_version        3.1
#    depends_lib-append      port:llvm-${llvm_version}
#}

After this, running "sudo portindex" cleared the issue. Finally I was able to install ld64 and gcc47.

Answer 2

The following commands solved my problem. Since the error was only for ld64 and cctools ports in my case.

sudo port clean ld64 cctools
sudo port install gcc47
