Message #08131
NameError: name 'cpp_Function' is not defined
Hello!
Can you help me to resolve problems with the recent dolfin installation? I had successfully used dolfin-0.7.2, but after installing dolfin-0.7.3 together with the most recent UFC,FIAT,FFC and INSTANT, I get a
"NameError: name 'cpp_Function' is not defined"
when importing dolfin into python.
I append to this message
1) the python output
2) the script used to install dolfin etc.
3) the output from the command scons enableDemos=yes
4) the output from the command ./scons.local &>scons.local.log
Please advise me, if I need to install additional packages, change the installation order or set any environment variables (dolfin.conf was sourced.) I have no experience with Scons, so I may have used those commands in a wrong way.
Thanks
Kerim

Warning: Installation directory is not in PATH.
To compile a program against DOLFIN, you need to update
your environment variables to reflect the installation
directory you have chosen for DOLFIN. A simple way to do
this if you are using Bash-like shell is to source the
file dolfin.conf:
source dolfin.conf
This will update the values for the environment variables
PATH, LD_LIBRARY_PATH, PKG_CONFIG_PATH and PYTHONPATH.
