Weasyprint: Weasyprint 0.21 on Ubuntu 12.04 LTS 64 bit

[acidjunk]

Hi,

I'm running Weasyprint on OSX and Ubuntu12.04 32 bit without any problems and I have to say I think it's the best PDF lib out there.

I tried to install it on a 64 bit Ubuntu 12.04 production server also:

Deps:
apt-get install python-dev python-pip python-lxml libcairo2 libpango1.0-0 libgdk-pixbuf2.0-0 libffi-dev shared-mime-info

Then:
pip install WeasyPrint

No errors where reported and pip installed some stuff

When I try to run weasy print

Traceback (most recent call last):

OSError: cannot load library pango-1.0: pango-1.0: cannot open shared object file: No such file or directory

The pango lib is installed correctly and located in /usr/lib/x86_64-linux-gnu

Any help is appreciated.

The pango lib is installed correctly and located in /usr/lib/x86_64-linux-gnu

I find this surprising. Doesn’t APT packages install stuff directly in /usr/lib?

Anyway, try setting this environment variable: LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu, assuming that’s the directory containing a .so file for Pango.

I solved itself; So I think it had something to do with my environment. Maybe a logout/login was all it took after installing the deps...

Thanks for your swift reply (and this amazing PDF lib).

I have this problem how did you fix it?

[stefankoegl]

Same here

[lorenzopiquer]

I fixed it in ubuntu 14.04:
apt-get install pango1.0-tests

I fixed it in ubuntu 14.04:
apt-get install pango1.0-tests

It also solve Ubuntu 20.04 server.

[SimonSapin]

It’s likely not the tests package that helps but its dependency libpango-1.0-0 or libpangocairo-1.0-0

[hildogjr]

Yes, thanks @SimonSapin . I just could not find that the package correct name was libpango-1.0-0 instead libpango1 like libcairo2 that I installed (solving the first part of the issue).

This is the better aproach: apt install libcairo2 libpango-1.0-0 libpangocairo-1.0-0
