ImageMagick and OS X Lion trouble

Question

[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?

Solution 1

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

Solution 2

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.

Solution 3

brew uninstall imagemagick
brew install imagemagick --build-from-source

worked for me

Solution 4

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

Solution 5

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

Don't forget to install xquartz.macosforge.org/landing as well. And you're good to go

[rroche]

maybe we should start comparing our brew installed libs

[Olivier Lalonde]

Here's the error message I was getting by the way: syskall.com/trouble-installing-imagemagick-on-os-x-1072 . Hope this fix works for someone else!

Howdy I tried this on a fresh Mountain lion install and it fails at the configuration stage configure: error: libltdl is required for modules build. I am relatively new to compiling and installing binaries from source, can you provide a suggested best method to installing the required libltdl library?

[firien]

I had originally used the install script mentioned by @rroche on my snow leopard install. After the Lion upgrade i was able to use the code above because i had all the library dependencies installed already. The above code will NOT work on a fresh install.

[firien]

the script mentioned by @23inhouse appears to work on mountain lion

[Rider_X]

I ended up installing the command line tools from Xcode, which seems to install a relatively recent version of ImageMagick.

[chris Frisina]

This doesnt play as nice with homebrew, as linkingvia brew link is done. Manual links might/may/likely willl need to be done afterwards for complete access

[Simon Perepelitsa]

Worked for me without linking.

[LevB]

@user192411, because ImageMagick require libtool to be compiled.

[lhunath]

Just brew install libtool appears to works just as well... Why the --universal and manual link call afterwards?

[bernstein]

this is not necessary just do a brew install libtool (since the precompiled imagemagick misses to download this dependency)

[Drew]

This worked for me, though I had to do a brew link libtool --force since it was bitching about Keg-only installations. brew doctor also bitches about libtool. What's that about?

[SJP]

This worked for me too, thanks. even the brew install libtool was not working.

[arun15thmay]

universal gives a single binary file which can be used for both 32bit and 64bit architectures. I think this is needed for Imagemagick to work.

[glerYbo]

To reinstall: brew reinstall libtool --universal && brew unlink libtool && brew link libtool

[fregas]

I was getting this error with PNGs despite having libpng installed. Just doing the --build-from-source fixed it. :)

[thewoolleyman]

see kenorb's answer: After mavericks upgrade you have to uninstall/reinstall libtool, even if the latest version is already installed.

[Alan Thompson]

Saved my build of octave. I also had to do brew unlink libtool && brew link libtool, brew uninstall imagemagick, brew install imagemagick --build-from-source, then brew link --overwrite imagemagick`

[Meekohi]

reinstalling libtool did not help me, but this worked.

[Jonik]

Worked for me on Mavericks (10.9.3).

[Pedro]

I think all you need is to relink the packages. See this answer for a suggestion: apple.stackexchange.com/questions/123900/…

[sholsinger]

I had to uninstall both imagemagick and libtool and reinstall libtool with the --universal flag then install imagemagick again.

[typeoneerror]

holy, you just solved me so much headache! currently this is the correct answer.

[marman]

Thanks dude brew doctor was the answer, I actually have other libraries being link.

[michele b]

and on El Capitan (10.11). I additionally needed to chown -R myusername a few folders (/usr/local/bin, /usr/local/share, /usr/local/etc), and replace the last line with brew unlink pillow && brew link pillow. Thanks a ton!

[Gerold Meisinger]

I had DYLD_LIBRARY_PATH exported from a previous manual installation which confused the brew installation. Close all terminals and retry.
