Thanks for answering me on a public holiday.  The reason is, I need the Optimisation library, to be used in the Interaction Geometry functor.  I want to give input and take output from the library to do calculations.  Unfortunately the library is in python.  

 

I found one C and  one C++ libraries, but I have compatibility problems.  One is (NAG), they require gcc-3.2.3 and RedHat for Intel64bit.  The other one (CVXOPT++) has the shared library problem.  I have tried fixing them both seriously before giving them up.  Going for FORTRAN or Matlab would be tougher than python.
 

Since I want to use the python library to perform calculations for my Interaction functor, I will have to connect it to C.  If I can run periodicpythonrunner from C, for my purpose, please explain more to me.  If not, the problem that the python script file, which contains my function, cannot detect yade's syntax/functions like O.bodies[1],etc .  Please help me.     

 

 

Yours,

 

Boon
