ld64 build fails with "command execution failed"

[mgs0lid_sn4ke@…]

Hi,

While installing gcc49, ld64 build fails. See output below :

sudo port install gcc49
Password:
--->  Computing dependencies for gcc49
--->  Dependencies to be installed: ld64 libgcc libmpc mpfr
--->  Building ld64
Error: org.macports.build for port ld64 returned: command execution failed
Error: Failed to install ld64
Please see the log file for port ld64 for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_ld64/ld64/main.log
Error: The following dependencies were not installed: ld64 libgcc libmpc mpfr
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets
Error: Processing of port gcc49 failed

Could you help on this issue ?

Thanks in advance

In the future, please Cc the port maintainers (port info --maintainers ld64), if any.

This file is provided by the dyld-headers port, which is a build dependency of ld64. Do you have that port installed? Does /opt/local/include/mach-o/dyld_priv.h exist?

[mgs0lid_sn4ke@…]

The file does not exist because dyld-headers was not installed as a build dependency. I installed it manually and it works now. Thanks.

[larryv (Lawrence Velázquez)]

Okay, not sure how that might have happened; MacPorts should have made sure dyld-headers was present.

I don't get it, it's my second ticket since I've tried to build gcc49 after reinstalling MacPorts.. and it's still not working. I am going to open another ticket but I think something might corrupted in my new installation.
