I've started to look into why the forcefield extension in Avogadro is
broken on windows and linux, and there is definitely a problem in
openbabel. For instance, the following test code produces the
following output:
d...@ez02:/tmp/fftest$ cat t.cpp
#include <stdio.h>
#include <openbabel/forcefield.h>
using namespace std;
using namespace OpenBabel;
int main()
{
cout << OBForceField::FindForceField("MMFF94") << endl;
}
d...@ez02:/tmp/fftest$ g++ -I/usr/include/openbabel-2.0/ -lopenbabel t.cpp -o t
d...@ez02:/tmp/fftest$ ./t
0
So it appears that the forcefield lookup is failing. After a digging
through OB's plugin.* for a while, I'm not any closer to finding a
solution. Do any of the OB devs have an idea what may be going on?
This worked fine up until a few days/weeks ago with OB trunk, so it is
likely a recent change.
