Issue installing libgcc on elcaptain

[Baaaaam (Mouginot Baptiste)]

I try to install libgcc on el captain... and I got :

Error: org.macports.build for port libgcc returned: command execution failed
Please see the log file for port libgcc for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc5/libgcc/main.log
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets
Error: Processing of port libgcc failed

The main.log says:

:info:build checking for suffix of object files... configure: error: in `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc5/libgcc/work/build/x86_64-apple-darwin15/libgcc':
:info:build configure: error: cannot compute suffix of object files: cannot compile
:info:build See `config.log' for more details.

Please attach the config.log, which might be in one of the two directories mentioned.

Same issue here with el captain...

@mouginot.baptiste, the config.log you attached does not appear to be the correct one. The gcc build creates multiple config.log files. Look for the one that contains the string "cannot compute suffix of object files".

@p.rousset: please attach your config.log file as well.

correct config.log

@ryandesign : I upload the correct one... sorry about the first one...

I ran into the same problem then found out it's caused by my firewall app. So make sure you disable any outbound firewall such as Little Snitch running in the background.

I'm having problems installing libgcc on El Capitan as well. My error log looks different, though. It's complaining about an illegal instruction in libgcc2.c:

:info:build     if (isnan (c)) c = COPYSIGN (0, c);

Possibly there's a header it can't locate that defines the COPYSIGN macro?

ETA: it can't be the macro, because it's defined in the same source file, and used without complaint in the two lines just before the failing one. Also, "isnan" is used in a conditional that governs the code block this sits in, so that can't be the issue, either.

Follow-up: apparently my problem was fixed by a from-source reinstall of the "gmp" package (following advice from a different ticket: #41364)

Both of these config.logs say the problem is:

/opt/local/bin/as: assembler (/opt/local/bin/clang) not installed

Jeremy, any idea what's going on here? Why is /opt/local/bin/as expecting /opt/local/bin/clang to exist?

cctools' as driver can be configured to use clang as the assembler.

I disabled that in r142831 as it's not quite ready for our use. If you have the older revision, it will work if you port select clang to something other than none.
