Problem Hotlist

MacPorts stops working after installing Xcode 4.3

Support for Xcode 4.3 was added in MacPorts 2.0.4. If you have an earlier version of MacPorts, you will need to upgrade to be able to use Xcode 4.3.

xcode-select

There have been reports of xcode-select not pointing to the new Xcode location for some users after upgrading to 4.3. If you are having problems even with the latest MacPorts version and xcode-select -print-path does not print /Applications/Xcode.app/Contents/Developer on your system, then you need to run:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

This is particularly important for people who have error messages referring to their old compiler locations after installing Xcode 4.3: you need to reinstall the package that stored the old compiler location if you see an error message like this:

error: can't exec '/Developer/usr/bin/xcodebuild' (No such file or directory)

So far this error is seen in previously-built perl and python when building perl or python modules.

Note you might have an older version of the xcode-select tool in case you installed Xcode 4.2 after installing the Mac OS X 10.7.3 update. If the command xcode-select -version returns version 2003 this is from Xcode 4.2 and we recommend to install the update once again with the ​Mac OS X 10.7.3 combo updater. The current xcode-select version that comes with Mac OS X 10.7.3 identifies itself as version 2307.

Xcode License Agreement

When attempting to build a port which compiles an OS X app (e.g., gimp-app), the compilation may fail with an xcodebuild error. One of the cause of this is that an initial run of xcodebuild from the terminal is needed to accept the EULA before any compilation can proceed. Run:

xcodebuild -license

from a terminal window and follow the prompts. After accepting the EULA, rebuild the port again.

A port build fails on Snow Leopard with: "file is not of required architecture"

If you had MacPorts installed before upgrading to Snow Leopard, see Migration.

A port fails to build when using Xcode 4

gcc has been the compiler collection MacPorts has used by default up until Xcode 4, in which Apple has switched to the llvm/clang compiler collection. These are new compilers and many programs have not yet been tested with them, and some ports will fail as a result. Using a different compiler may work better for a particular port. If the below workarounds enable you to install a port that failed with its default compiler, file a ticket and let us know so we can fix it. Portfile authors, see wiki:PortfileRecipes#compiler.

Xcode 4.2 and later

If a port foo fails to build and you're using Xcode 4.2 or later, the default compiler is clang; try compiling with llvm-gcc-4.2 instead:

sudo port clean foo
sudo port install foo configure.compiler=llvm-gcc-4.2

If that fails, try installing the apple-gcc42 port and compiling with that:

sudo port clean foo
sudo port install apple-gcc42
sudo port install foo configure.compiler=apple-gcc-4.2 configure.cxx=g++-apple-4.2

Xcode 4.0 and 4.1

If a port foo fails to build and you're using Xcode 4.0 or 4.1, the default compiler is llvm-gcc-4.2; try compiling with clang instead:

sudo port clean foo
sudo port install foo configure.compiler=clang

If that fails, try using gcc-4.2:

sudo port clean foo
sudo port install foo configure.compiler=gcc-4.2

man port fails with error message

Error message:

$ man port
Cannot open the message catalog "man" for locale "de_DE.UTF-8" (NLSPATH="<none>")
No manual entry for port

Workaround:

Add the following line to your .profile or .bash_profile.

unset MANPATH

port fails with: Image error: /opt/local/bin/a2p…

Error message:

Error: Activating perl5 @5.12.3_1 failed: Image error: /opt/local/bin/a2p is being used by the active perl5.8 port.  Please deactivate this port first, or use the -f flag to force the activation.

The perl5.8, perl5.10 and perl5.12 ports used to conflict with each other unless a particular variant was selected. This has now been solved by suffixing their binaries with a version number, and the perl5 port installs links without any suffix. The old versions of perl5.x conflict with the current version of perl5.

Fix:
To fix this issue, upgrade whichever of the above ports that you have installed.

port upgrade installed and \( perl5.8 perl5.10 perl5.12 \)

Fetch failures

If fetch failed for a port, you can still get the distfile from anywhere else. For example, the ​main MacPorts distfiles mirror contains most ports' distfiles, or maybe the homepage of the software lists alternative download locations for source tarballs. Just download the distfile and save it to the path shown by port distfiles <portname>. Make sure you get a file with exactly the same name (watch out for .tar.gz and .tar.bz2!) If a port clean --all has been done the distfile directory will have been removed. The directory for each port is created at the beginning of the fetch phase.

Note: Checksum failures after a fetch are typically a separate issue. See the FAQ.

Image error: /opt/local/bin/xmlwf already exists and does not belong to a registered port

When installing a port with MacPorts, you encounter this error:

Error: Target org.macports.activate returned: Image error: /opt/local/bin/xmlwf already exists and does not belong to a registered port.  Unable to activate port expat.

xmlwf is a part of the expat port (which is a dependency of many other ports, and thus is likely to be one of the first ports to ever get installed), but for some reason this file already exists on your computer, and MacPorts did not install it.

One possible reason for this is that you have installed a 3rd-party software package -- possibly ​gprolog or ​swi-prolog -- which was itself built with MacPorts, set to its default prefix, and therefore conflicts with your normal use of MacPorts in its default prefix. The developers of the 3rd-party package you installed should not have distributed their software in this manner; they should have configured MacPorts in a custom prefix instead, one that is unique to their software. (For example, in the case of swi-prolog, /usr/local/swi-prolog or /opt/swi-prolog would be good choices.)

Another possible reason is that you previously had MacPorts (and expat and probably other ports) installed, then somehow uninstalled MacPorts itself, or at least its registry of which ports are installed, without actually uninstalling those ports, and have now installed MacPorts again with a clean registry, which therefore thinks no ports are installed, though some still are.

Either way, the cleanest solution at this point is to follow the ​MacPorts uninstallation instructions. This will remove the 3rd-party software package that installed itself unannounced into MacPorts' prefix, and/or ports installed by your prior MacPorts installation. Then you can ​install MacPorts again.

A command failed to run with a message referring to libpng12.0.dylib

Error message:

dyld: Library not loaded: /opt/local/lib/libpng12.0.dylib

Explanation:
When the libpng port was updated from 1.2.x to 1.4.x, the libpng library version changed. Software always links against a specific library version, so the ports you currently have installed that depend on libpng are linked against a now-nonexistent version of the libpng library. To fix this problem, all ports that depend on libpng will need to be rebuilt so that they link with the new version of the libpng library. This may be quite a few ports.

Workaround:
We have tried to find all affected ports and incremented the revision number. In most cases a simple upgrade should get them all fixed.

sudo port selfupdate
sudo port upgrade outdated

If this does not help, force a rebuild of the port in question by using the following command:

sudo port -n upgrade --force $portname

You should also ​file a ticket against the port in question.

A port failed to build with a message referring to 1/lib: No such file or directory

Error message:

apple-darwin9-gcc-4.0.1: 1/lib: No such file or directory
make: *** Error 1

Explanation:
When upgrading from Tiger to Leopard without removing the previous Mac OS version, updated versions of some libraries in /usr/ and /usr/lib/ are moved from /old/path/ to /old/path 1/. Notice the space before 1. This makes some configure scripts build bad build instructions, making the build phases of several ports fail.

Two incriminated directories have been encountered :

/usr/X11R6 1/
/usr/lib/ruby 1/

Workaround:

In order to fix this problem, you can remove the backups created by the installers, and then clean the work directory of the failed port so that its configure script will be re-run:

port clean --work <port>

Corrupt Filemap

Error message:

Error: unknown node kind in database (database is corrupted?)

Workaround:

Probably something went wrong while a port was being (un)installed or (de)activated, such as a kernel panic or the machine losing power. You can fix the database file (/opt/local/var/macports/receipts/file_map.db) by downloading the following script:

http://svn.macports.org/repository/macports/contrib/repairfilemap/repairfilemap.tcl

Follow the instructions in the comments at the beginning of the script. You can invoke the script by typing:

chmod +x repairfilemap.tcl
sudo ./repairfilemap.tcl
