Executing a C++ program in another

[rajistephen]

hai friendz,

I am a Bioinformatics Masters degree student. I am doing my final semester project in the topic Molecular Docking on C++ in Linux platform. During the programming I felt a problem in calling/executing a progam in to my program. I have to call a program which accept a PDB file( which is from my program) as input and gives an output file containing an energy value. I used many syntaxes including,
system("./progam name");
But result is not getting & the window gets hanged for long time.
Can you please send your idea regarding any possible solution of this problem. Hope ur reply soon.

regards,

Raji Stephen

Hi frrossk,

Thank you for this valuable information. The program which I have to execute inside my C++ program is in binary form. My ultimate problem is I have to execute this nearly hundred times for different input files from my program. This can't be done parellel because of some selection creteria. If I use system("process1"); where should I place the input file in order to identify it by that program?. Heard from somewhere that only system("process1"); line will execute at the end of the host program. Is that true?

Can it be possible to convert a program in the binary form to its original C++ format?
Hope ur kind help.

Thanking you.
