libMagickWand.so.4 & libMagickCore.so.4 libraries missing with latest ImaeMagick update..

[Martin Cigorraga]

Hello Damien:

can you please rebuild Emacs against the latest ImageMagick version? As I upgrade ImageMagick (I use it on a daily basis, just like Emacs) I've found that Emacs stopped working throwing with the following error message:
"emacs: error while loading shared libraries: libMagickWand.so.4: cannot open shared object file: No such file or directory"

Thank you very much for contributing this must-have PPA!
Best regards.

Dear Martin,

could you please report your bug to https://bugs.launchpad.net/emacs-snapshot/ (which is my official issue tracker) instead of here (which is Ubuntu's)?

Then, could you please execute these lines and write the result in your bug report?

$ apt-cache policy emacs24
$ apt-cache policy libmagickwand5
$ lsb_release -c

Finally, could you please tell me all the steps to reproduce your problem starting with "emacs -Q"

Here it goes (and sorry for the mess!):

## Before symlinking the libraries, see comment at bottom ##
j:0 ~ > apt-cache policy emacs24
emacs24:
  Installed: 24.3+1-2~ppa1~precise1
  Candidate: 24.3+1-2~ppa1~precise1
  Version table:

j:0 ~ > apt-cache policy libmagickwand5
N: Unable to locate package libmagickwand5

j:0 ~ > lsb_release -c
Codename: luna <--- (Precise Pangolin)

j:0 ~ > emacs -Q
emacs: error while loading shared libraries: libMagickWand.so.4: cannot open shared object file: No such file or directory

Now, it's weird I can't find anywhere here at Launchpad the comment I posted right next to my above mentioned report where I stated that symlinking "ln -s /usr/lib/libMagickWand.so.5 /usr/lib/libMagickWand.so.4" and "ln -s /usr/lib/libMagickCore.so.5 /usr/lib/libMagickCore.so.4" (as seen on this VectorLinux forum post: http://forum.vectorlinux.com/index.php?topic=15913.msg100288#msg100288) solves the issue!

## After symlinking above libraries ##
j:0 ~ > emacs -Q
;; This buffer is for notes you don't want to save, and for Lisp evaluation.
;; If you want to create a file, visit that file with C-x C-f,
;; then enter the text in that file's own buffer.

(That is, opens Emacs in a buffer as expected...)

Please let me know if I can be of further assistance.
Cheers!
