images to pdf - segmentation fault

[radioboy]

I've been trying to convert a series of images to a single pdf file in Linux Mint 8 (x64), using

Code: Select all

convert *.jpg file.pdf

The result is always a segmentation fault. I have tried using jpg and tif images.
The convert version is: ImageMagick 6.5.1-0 2009-08-27 Q16 OpenMP.
I'm using the Ubuntu Karmic repositories, and until now there are no updates available.
I have backports and getdeb repositories activated.

I read in another thread that this could be due to having multiple versions of imagemagick.
I found that, for example, I have in /usr:

Code: Select all

./lib/libMagickWand.so.2
./lib/libMagick++.so.2
./lib/libMagickCore.so.2.0.0
./lib/libMagickCore.so.2
./lib/libMagickWand.so.2.0.0
./lib/libMagick++.so.2.0.0

I don't know if it makes sense, but I tried moving first the .2 versions to a temporary folder and then the .2.0.0 versions (restoring the .2 versions before, of course) but in both cases I get:
convert: error while loading shared libraries: libMagickCore.so.2: cannot open shared object file: No such file or directory.

The output of "ldd /usr/bin/convert" is:

(But I don't know well what to do with this.)

Using convert -debug annotate *.JPG file.pdf throws again just Segmentation fault.
I was able to do this in Opensuse about a month or two ago.
Could this be also a case of conflicts of library versions? I tried installing the latest version I found (6.5.8-9) from
source and installing, and I get the same segmentation fault. This time, however, I couldn't uninstall the older version since there are too many programs that have Imagemagick as dependency.
By the way, my installed packages as given by dpkg --get-selections | grep magick are:

Code: Select all

imagemagick					install
libmagick++2					install
libmagickcore2					install
libmagickwand2					install
perlmagick					install

Thanks!

We need a stack trace to investigate the problem. Type

• gdb convert
  run *.jpg file.pdf
  where

Post the result.

Lets see if the problem persists in recent releases of ImageMagick. Download the latest ImageMagick release and install:

• wget ftp://ftp.imagemagick.org/pub/ImageMagi ... 8-9.tar.gz
  tar xvfz ImageMagick-6.5.8-9.tar.gz
  cd ImageMagick-6.5.8-9
  ./configure
  make
  sudo make install
  /usr/local/bin/convert *.jpg image.pdf

If that works, the problem may be associated with the ImageMagick 6.5.1 release. Although we downloaded ImageMagick-6.5.1-10.tar.gz and could not reproduce the problem. Conversions from JPEG to PDF worked without complaint.

Another option would be to use a compression method other than the default JPEG. Add +compress to your command line, for example, and your command should complete.

[radioboy]

Adding the +compress option solved it.

I tried installing the version you suggested, but I still got a segmentation fault.
I couldn't uninstall the previously installed version, though, since doing that would break a very long list of dependencies;
then, I still wonder if that new segmentation fault could be due to multiple library versions.
I run convert again without the "+compress" option with gdb, but I got an empty stack.

So I still prefer to use the old version with "+compress", since it works perfectly.
Thank you very much!
