Hi ,
I wanted to use the rdkit version from github under a virtualenv in python.
So I wanted to compile rdkit from source instead of using the Ubuntu
supplied python-rdkit.
The steps I followed were
1) removed Ubuntu supplied python-rdkit , libpython2.7-dev and
libboost-dev ( ver 1.49 )
2) Compiled Python 2.7.5 and boost 1.53 with suggested flags and settings:
Python: /configure CFLAGS=-fPIC --enable-unicode=ucs4 --enable-shared ,
boost :./bootstrap.sh --with-libraries=python,regex; ./b2; ./b2 install
3) I then ran the make script with
cmake -D PYTHON_LIBRARY=/usr/local/lib/libpython2.7.a ..
4) cmake did tell me that it was using the Boost 1.53 I compiled and rather
strangely for the python library the correct *.a file with a weird version
3.3.2 ( I had installed python3.3.2 libs in /usr/local/bin as well)
-- Found PythonLibs: /usr/local/lib/libpython2.7.a (found version "3.3.2")
-- Found PythonInterp: /home/hari/.virtualenvs/ptn2p7p5/bin/python (found
version "2.7.5")
5) Failure message
After this when I compile it fails with message
Scanning dependencies of target RDBoost

make[1]: *** [Code/RDBoost/CMakeFiles/RDBoost.dir/all] Error 2

ANy ideas what I am doing wrong.
Thank you for all your help
Hari
