[Reza Farrahi Moghaddam <imriss@xxxxxxxxx>]

In cygwin, it seems that the main Lib is in /lib (where python2.5\site-packages can be found).
So, I changed the configuration commnad to the following to force it to be installed in /lib:

$ ./configure --enable-petsc --with-petsc-dir=/home/rfarahi/math/petsc-2.3.3-p11 --enable-pydolfin --prefix=/.

But, the result is exactly the same. 

The contents of dolfin.conf is now as follows:
export PATH="/./bin:$PATH"
export LD_LIBRARY_PATH="/./lib:$LD_LIBRARY_PATH"
export PKG_CONFIG_PATH="/./lib/pkgconfig:$PKG_CONFIG_PATH"
export PYTHONPATH="/./lib/python2.5/site-packages:$PYTHONPATH"

Another point is that there is no setup.py in the src/pydolfin directory. However, the dolfin files (assemble.py, _dolfin.a, etc) have been created in the /lib/python2.5/site-packages/dolfin

The error: No module named _dolfin

Hello,

I am not very familiar with cygwin, but did you set the environment 
variables defined in the file dolfin.conf in the main dolfin directory?
