Hi
I'm trying to get Pybel (OpenBabel 2.3.2) to export to PNG format in
Centos 6.5.
As I understood from the the docs, I just need to install Cairo; the
packages for Centos are cairo and cairo-devel. I also installed libpng
and libpng-devel.
This is the compilation command and (relevant) output:
[yo@mol build]$ cmake ../openbabel-2.3.2 -DPYTHON_BINDINGS=ON
-DEIGEN2_INCLUDE_DIR=/home/yo/openbabel_compilation/eigen-eigen-b23437e61a07/
-DEIGEN3_INCLUDE_DIR=/home/yo/openbabel_compilation/eigen-eigen-6b38706d90a9/
-- Using included inchi library.
-- Could NOT find wxWidgets (missing: wxWidgets_FOUND)
-- Cairo found. PNG output will be supported.
-- Attempting to build the GUI
-- wxWidgets not found => GUI will not be built
-- Python bindings will be compiled
-- Configuring done
-- Generating done
-- Build files have been written to: /home/yo/openbabel_compilation/build
It says "Cairo found. PNG output will be supported.". Indeed, I get a
png if I run:
/usr/local/bin/obabel -:"CC(=O)Cl" -O mymol.png -xO smi
But when I try to run my code using pybel
[yo@mol MDB]$ python get_data.py
Traceback (most recent call last):
File "get_data.py", line 30, in name_to_img
pybel.readstring('smi', str(v_name)).draw(show=False,
filename=img_path)
File "/usr/lib64/python2.6/site-packages/pybel.py", line 502, in draw
raise ImportError(errormessage)
ImportError: PNG output format not found. You should compile Open Babel
with PNG support. See installation instructions for more information.
I can export to PNG using a script sample for Cairo and using obabel
directly, so in this point I don't even understand the error from pybel.
How do I get PNG support or at least understand where the problem is?
Thank you
Carolina
