[edit] I was troubleshooting problems with my development environment when I noticed one of my problems was the dependency on ImageMagick, since it's a vital part of my app.
After upgrading to OS X Lion (10.7) i no longer had ImageMagick available, i then tried installing again using MacPorts without success, i then installed from source, and the install wasn't very successfully i had convert and identify but it output error messages that i unfortunately dont have anymore, i by some strange reason decided to remove all of my MacPort libraries and started using Homebrew, i tried installing ImageMagick, it installs OK but when i try to use it throws this error
dyld: Library not loaded: /opt/local/lib/libltdl.7.dylib
Referenced from: /usr/local/bin/convert
Reason: Incompatible library version: convert requires version 11.0.0 or later, but libltdl.7.dylib provides version 10.0.0
Trace/BPT trap: 5
I read online but i have no clue on whats going on here, i found that libltdl is called libtool, and that i obviously need to upgrade it to a newer version, but i havent found any indication of how or where to find the source, or if this should be already be handled by homebrew and why it hasn't.
I tried installing ImageMagick again from source using this installer script https://github.com/masterkain/ImageMagick-sl but when i try to use convert it throws a similar error.
$ convert gnome.jpg -resize 50% gnome_.jpg
dyld: Library not loaded: /opt/local/lib/libltdl.7.dylib
Referenced from: /usr/local/bin/convert
Reason: Incompatible library version: convert requires version 11.0.0 or later, but libltdl.7.dylib provides version 10.0.0
Trace/BPT trap: 5
$ which convert
/usr/local/bin/convert
What can i do to solve my problem?
I also upgraded to Lion and lost ImageMagick, although i'm getting different errors.
i found a Lion distribution on imagemagick.org. not a big fan of the DYLD_LIBRARY_PATH environment variable but it works.
ok scratch that. i just downloaded the ImageMagick source and re-compiled:
cd /tmp
curl -OL ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz
tar -xzf ImageMagick.tar.gz
cd ImageMagick-6.7.2-7/
./configure --prefix=/usr/local --disable-static --with-modules --without-perl --without-magick-plus-plus --with-quantum-depth=8 --disable-openmp --with-gs-font-dir=/usr/local/share/ghostscript/fonts
make
sudo make install
On 10.8 I solved this issue with:
brew install libtool --universal
brew link libtool
If you don't know what brew is, visit https://github.com/mxcl/homebrew and its wiki.
brew uninstall imagemagick
brew install imagemagick --build-from-source
worked for me
I too use homebrew for installing packages but imagemagick stopped working after upgrading OSX 10.8 to 10.9 (Mavericks). I had to do the following steps:
brew uninstall imagemagick
brew uninstall libtool
brew install libtool --universal
brew install imagemagick --build-from-source
Why the --build-from-source? Well for me running brew install imagemagick on its own to install the pre-built binary wasn't sufficient; it fixed the original 'dyln' error but was replaced with:
unable to load module `/usr/local/Cellar/imagemagick/6.8.7-7/lib/ImageMagick//modules-Q16/coders/png.la': file not found @ error/module.c/OpenModule/1277
On Mountain Lion OSX,
Even with the updated brew for imagemagick(which includes libtool), this error seemed to happen to me.
so i fixed it using the following commands
brew uninstall libtool
brew install libtool --universal
brew link libtool --force
For others looking and still having trouble, I used this:
On 10.8, with brew, I solved this issue with:
brew install graphicsmagick
For the googlers: If you happened to have it installed with brew beforehand, you'll need to reinstall by running brew uninstall graphicsmagick before installing again. Easy.
This helped me after restoring OS X 10.9.3 from time machine.
brew uninstall imagemagick
brew uninstall libtool
brew install libtool --universal
brew unlink libtool && brew link libtool
brew install imagemagick
brew install Homebrew/python/pillow
brew link --overwrite pillow
The same problem might occur with OSX Mountain Lion (preview 4). I had to configure some parts separately because there are some library incompatibilities:
dyld: Library not loaded: /usr/local/lib/libjpeg.8.dylib
Referenced from: /usr/local/bin/convert
Reason: Incompatible library version: convert requires version 13.0.0 or later, but libjpeg.8.dylib provides version 9.0.0
I had to add --with-fontconfig=no, --with-lzma=no and use /opt/local/share/... instead of /usr/local/share/... for the ghostscript fonts:
cd /tmp
curl -OL ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz
tar -xzf ImageMagick.tar.gz
cd ImageMagick-6.7.8-0/
./configure --prefix=/usr/local --disable-static --with-modules --without-perl --without-magick-plus-plus --with-quantum-depth=8 --disable-openmp --with-fontconfig=no --with-gs-font-dir=/opt/local/share/ghostscript/fonts --with-lzma=no
make
sudo make install
I could fix the ImageMagick problem by installing corresponding package from cactuslab site.
Then by setting the PATH variables in terminal:
export MAGICK_HOME="/usr/local/ImageMagick/"
export PATH="$MAGICK_HOME/bin:$PATH"
export DYLD_LIBRARY_PATH="$MAGICK_HOME/lib/"
If you're using Homebrew, try the following command:
brew doctor
to diagnose the common problems.
One of it could be to remove DYLD_FALLBACK_LIBRARY_PATH variable from your ~/.profile if you have it.
Or you have to re-install libtool by:
brew reinstall libtool --universal && brew unlink libtool && brew link libtool
I tried most of the solutions above and they didn't work. Here's how I fixed my problem:
brew install imagemagick;
brew install freetype;
cd /usr/X11/lib/;
sudo mv libfreetype.6.dylib libfreetype.6.dylib.orig;
sudo ln -s /usr/local/opt/freetype/lib/libfreetype.6.dylib libfreetype.6.dylib
Tested on OS X 10.7.2
For 10.7.8 and up, you have to install the php version and not the pecl version. Depending on your version of php you've install with Macports you can either do:
sudo port install php-imagick
sudo port install php5-imagick
sudo port install php53-imagick
sudo port install php54-imagick
Remember only to do the one of your current version of php.
