apple-gcc42 failed to compile: conflicting types for 'psignal'

[macports@…]

I was trying to install mkvutoolnix but the installation stopped when compiling apple-gcc42. I'm on a core i7 macbook air (2011) with Lion.

$ uname -a
Darwin MacBook-Air.local 11.2.0 Darwin Kernel Version 11.2.0: Tue Aug  9 20:54:00 PDT 2011; root:xnu-1699.24.8~1/RELEASE_X86_64 x86_64

$ xcodebuild -version
Xcode 4.2
Build version 4D199

I'm attaching the complete log file, here's the first error I see:

That code in libiberty/strsignal.c is only included when:

#ifndef HAVE_PSIGNAL

Can you please attach libiberty/config.log

[macports@…]

Attaching config.log from path /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_apple-gcc42/apple-gcc42/work/objroot/obj-x86_64-x86_64/libiberty/ Hope it helps, thanks.

It looks like dsymutil was bugged ... can you update to Xcode 4.3.2?

Can you provide the crash log for dsymutil?

I did the XCode upgrade and also a Port update. It worked! Thank you. Do you still want the dsymutil log? If you tell me were is it, I'll post it.

Jose

[jeremyhu (Jeremy Huddleston Sequoia)]

Yes, I'd like the dsymutil crash report just to make sure it really is fixed. Chances are that it is fixed, but you also might just no longer be tickling it. Please email it to jeremyhu@…, thanks.

I'll update the port to require XCode 4.3 on Lion.

[macports@…]

Can you tell me how to get that log?

[ryandesign (Ryan Carsten Schmidt)]

Crash logs are saved in ~/Library/Logs/DiagnosticReports/ and /Library/Logs/DiagnosticReports/
