Binary Inkscape dist crashes when MacPorts is installed

[Jochen]

The binary distribution of 0.46-2 and 0.47-pre1 crash on Leopard 10.5.7 when MacPorts is installed in parallel. When MacPorts is removed, it works just fine.

lsof reports Inkscape is opening the following files from MacPorts:

I tried removing /opt/local/bin from the PATH setting in:

/Applications/Inkscape.app/Contents/Resources/bin/inkscape

but get:

009-07-17 11:54:29.097 defaults[83215:10b]
The domain/default pair of (kCFPreferencesAnyApplication, AppleAquaColorVariant) does not exist
2009-07-17 11:54:29.110 defaults[83216:10b]
The domain/default pair of (kCFPreferencesAnyApplication, AppleHighlightColor) does not exist

(process:83193): Gtk-WARNING **: Locale not supported by C library.
 Using the fallback 'C' locale.

Emergency save activated!
Emergency save completed. Inkscape will close now.
If you can reproduce this crash, please file a bug at www.inkscape.org
with a detailed description of the steps leading to the crash, so we can fix it.

1) otool -L /Applications/Inkscape.app/Contents/Resources/bin/inkscape-bin
indicates that inkscape-bin looks for libraries in /opt/local/lib rather
than /Applications/Inkscape.app/Contents/Resources/lib

2) a problem in the section that attempts to add
.UTF-8 to LANG using /usr/share/locale/locale.alias

LANG="en_CA.UTF8" becomes ".UTF8"

ad 1) otool -L /Applications/Inkscape.app/Contents/Resources/bin/inkscape-bin
see explanation in bug #392693:
 'Inkscape's libraries all have install-names of /opt/local/lib, and Inkscape uses DYLD_LIBRARY_PATH to find them…'

@Jochen

1) launchd seems to launch an X11 version installed via macports? AFAIK Inkscape has no influence on that on Leopard 10.5.7.

2) Inkscape releases are built as universal binaries. Are you sure all (pre-installed) ports and dependencies are also installed with the same variants (including '+universal')? The wiki page <http://wiki.inkscape.org/wiki/index.php/CompilingMacOsX> recommends 'If you already have non-universal versions of these ports installed you may need to deactivate the port and rebuild it'.

If you need to keep ports with different variants, the best way is to set up separate instances/trees of MacPorts with a different base path (at least that's what I found recommended when searching the macports-users mailing list - archives at <http://lists.macosforge.org/pipermail/macports-users/>, as well as on the wiki page 'CompilingMacOsX' <http://wiki.inkscape.org/wiki/index.php/CompilingMacOsX#Installing_a_second_Macports_tree_.28recommended_approach.29>.

3) I don't know yet if DYLD_LIBRARY_PATH overrides install-names (if the libraries exist with their install-names on the local system) or acts as a fallback if the libraries can't be found under their install-names. One way to avoid possible conflicts when using both the packaged universal binaries from sf.net and local macports installations, is - as above - changing the local macports install-prefix to keep a separate tree for your own ports with a not-default install-path.

one caveat to my comments: I'm not a macports user myself yet - but preparing to do so and thus interested in any resulting conflicts and solutions.

This problem actually started happening for me in the last couple of days after upgrading Macports.

It is fixed in svn in r21860. I will build an upload a new 0.47 package in the morning.

The problem is Inkscape trying to read incompatible fontcaches from Macports. The fix is to modify Inkscape.app/Contents/Resources/etc/fonts/fonts/conf to remove the following line:
 <cachedir>/opt/local/var/cache/fontconfig</cachedir>

(Also, FWIW DYLD_LIBRARY_PATH does override the install-names. This wasn't an issue. But, I recently had a go at rewriting the install-names to thus not require DYLD_LIBRARY_PATH anymore. But the problem is that the path we require it too long for the space allocated to the install names in some libraries, so we might need to try doing something sneaky like installing macports in a prefix with a long name.)

[su_v (suv-lp)]

Thank you for the fix and the clarification regarding DYLD_LIBRARY_PATH!

[Michael Wybrow (mjwybrow)]

This is fixed in Inkscape-0.47-pre1-2.LEOPARD.dmg, which is on Sourceforge now.

[su_v (suv-lp)]

The same conflicts happens with Inkscape 0.46-3 Tiger on OS X 10.4.11 if fontconfig is installed via MacPorts (see bug #183322 comments 7-14). Modifying 'fonts.conf' as described in comment 4 fixes the issue.

[Michael Wybrow (mjwybrow)]

This is properly fixed in the Inkscape-0.47pre2-1.LEOPARD.dmg, up now on sourceforge -- the official package no longer uses the DYLD_LIBRARY_PATH magic. Instead all paths within the dylibs, executable and shared objects get rewritten to be relative to the executable during the packaging process.
