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

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

Answer 3

The ld64 package has been pulled from macports as of today:
http://www.macports.org/ports.php?by=name&substr=ld64
It was still available yesterday though.
However, the package did not build correctly when I tried it yesterday because of build errors with llvm-3.0.

Answer 4

The ld64 package is back on the index but it fails to build :-(
First there is a xcodebuild issue with the license agreement. I fixed it with the tip from 1. But now there's a build failure because of an undeclared identifier.

Answer 5

Run the following command; seems working for now.
sudo port selfupdate
sudo port install gcc47

Answer 6

I do not know how you get this problem. I am also encountering this problem after I upgrade my system to Mavericks. After check the main.log file, I found that the error is because the build cannot find . Then, I install the newest version Xcode Command Line Tools , it works! Hope my experience is helpful to you.
