Comic conversion error

[Landrovan]

Hi,

I just instal calibre 0.6.6 with the binary installer in ubuntu jaunty 32bits. I try to convert a comic (.cbz) to lrf. The convert failed with this error:
Traceback (most recent call last):

I install in the default folder (/opt/calibre).
The package imagemagick is installed on my system.


Thanks

Do you have a 64bit system?

Nope, just a 32bits system

calibre-debug -c "from calibre.utils.PythonMagickWand import _lib, _magick, _magick_error; print _lib, _magick, _magick_error"

You used the binary installer to install calibre?

Yes, I use:
sudo python -c "import urllib2; exec urllib2.urlopen('http://calibre.kovidgoyal.net/download_linux_binary_installer').read(); main()"
from the website. And I installed it in the default directory (/opt/calibre).

P.S. I was having 0.5.14 installed with the package manager (apt) before. I uninstall it before using the binary installer though. (if memory serve well)

calibre-debug -c "from ctypes import CDLL; CDLL('libMagickWand.so.1')"

Looks like a problem with a library on your system need by imagemagick. Try googling "undefined symbol: gzopen64"

[Landrovan]

OK found the problem. The binary installer put a file libz.so.1 in /opt/calibre. By renaming that file (so calibre use the one I have in /lib) corrected the problem.

Thanks!
