Missing libraries in calibre binary release for Linux

[davide125]

Hi,

while trying to setup a headless calibre install, I noticed that the binary install from http://calibre-ebook.com/download_linux is not really self contained: there are a number of missing libraries (identified using ldd), that prevent it to work on console-only systems, or on systems with a minimal X install. The missing libraries (checked against 0.8.16) are:

libcairo.so.2
libcroco-0.6.so.3
libdbus-glib-1.so.2
libgdk_pixbuf-2.0.so.0
libgsf-1.so.114
libICE.so.6
libpango-1.0.so.0
libpangocairo-1.0.so.0
libpangoft2-1.0.so.0
libpixman-1.so.0
libQtDesigner.so.4
libQtOpenGL.so.4
libQtScript.so.4
libQtScriptTools.so.4
libQtTest.so.4
libQtXmlPatterns.so.4
librsvg-2.so.2
libSM.so.6
libwmf-0.2.so.7
libXext.so.6
libXrandr.so.2
libXrender.so.1
libXt.so.6

Would it be possible to add these libraries to the binary package?

Thanks for your help!

Most of the libraries you list are not needed. You do need X installed.

I've looked a bit more into this: if we ignore the basic X libraries (libXext, libXt, libSM, libICE, libXrandr, libXrender), the remaining missing depends boil down to:

./lib/ImageMagick-6.6.7/modules-Q16/coders/svg.so
	librsvg-2.so.2 => not found
	libgsf-1.so.114 => not found
	libcroco-0.6.so.3 => not found
	libpangocairo-1.0.so.0 => not found
	libpangoft2-1.0.so.0 => not found
	libpango-1.0.so.0 => not found
	libgdk_pixbuf-2.0.so.0 => not found
	libcairo.so.2 => not found
	libpixman-1.so.0 => not found
./lib/ImageMagick-6.6.7/modules-Q16/coders/wmf.so
	libwmf-0.2.so.7 => not found
./lib/python2.7/site-packages/_dbus_glib_bindings.so
	libdbus-glib-1.so.2 => not found
./lib/python2.7/site-packages/PyQt4/QtDesigner.so
	libQtDesigner.so.4 => not found
./lib/python2.7/site-packages/PyQt4/QtScript.so
	libQtScript.so.4 => not found
./lib/python2.7/site-packages/PyQt4/QtScriptTools.so
	libQtScriptTools.so.4 => not found
./lib/python2.7/site-packages/PyQt4/QtTest.so
	libQtTest.so.4 => not found
./lib/python2.7/site-packages/PyQt4/QtXmlPatterns.so
	libQtXmlPatterns.so.4 => not found
./lib/qt_plugins/graphicssystems/libqglgraphicssystem.so
	libQtOpenGL.so.4 => not found

So none of the missing depends are in calibre itself, but they all come from libraries bundled in the binary release package. Still, the result is that the current binary release doesn't work on systems missing these libraries.

It maybe that the lib's CAN access these others, but there use in Calibre is such that they are not required. Have you tried installing it rather than checking for missing libs's? It may work.

[davide125]

hairybiker, I did. After installing libXext, libXt, libICE, libSM, libXrandr and libXrender using my distro package manager, the 'calibre-server' and 'ebook-conver' binaries at least start without library errors. Trying ebook-convert against a random recipe seems to work, except for the message:
"SVG rasterizer unavailable, SVG will not be converted"
which is probably due to the missing libraries used by ImageMagick SVG coder. I haven't checked the actual output yet, and I still have to try calibre-server.

ImageMagick is not used for SVG rasterization. That's why it's unnecessary to bundle it. SVG is handled by Qt. You're getting that message because you're not running ebook-convert under X. Many parts of calibre including the command line tools must be run in an X session. However, you don't need to run a full X session. You can use Xvfb and run the command in that so you never see an X desktop.
