While trying to install a port I got "Error: Failed to configure lbzip2"

Hi there,

While trying to install the port "argyll" I got an error with lbzip2.

The main.log is attached. Thanks for your attention!

MacPort lbzip2 main.log

The log points to a problem with your Xcode installation:

:info:configure checking whether the C compiler works... no
:info:configure configure: error: in `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_archivers_lbzip2/lbzip2/work/lbzip2-2.5':
:info:configure configure: error: C compiler cannot create executables
:info:configure See `config.log' for more details

The config.log in the directory mentioned might contain more clues. You could also just try running /usr/bin/clang --version from a shell. Have you installed Xcode and the Command Line Tools?

Thanks for your fast answer. I have the regular XCode 5.1.1 (seems to be the regular version vor OS X 10.8) with the cli tools.

/usr/bin/clang --version shows me the following:
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin12.6.0
Thread model: posix

I have already installed many ports that all seem to work so far.

I attach the config.log from the path /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_archivers_lbzip2/lbzip2/work/lbzip2-2.5/config.log

lbzip2 config.log from the compiler

I missed that this was an attempt to build lbzip2 +universal (that is, for more than one architecture). This was implied by argyll, because it can only be built as i386.

This log shows that it tried to build for i386, x86_64, and ppc. I assume you do not actually want to produce binaries for PowerPC. Please check the value of the option universal_archs in /opt/local/etc/macports/macports.conf. It is supposed to only list x86_64 and i386 for Intel Macs as shown below. And while you are at it, also compare and replace other values with their defaults as defined in macports.conf.default right next to the configuration file.

universal_archs         x86_64 i386

THANKS A LOT!!!

universal_archs x86_64 i386 ppc

Shame on me! This was my problem - no clue why this was in my config file. All working fine now.
