xxxFoam > log, Failed! xxxFoam, succeed! ?.....

Hi guys,

I run into a very weird case....

In my code, its just a c++ program for now. It does not need any OpenFOAM libraries. It compiles no warning, no error. Runs smoothly.

But when I add this:

Code:

int main(int argc, char *argv[])
{
    #include "setRootCase.H"
    #include "createTime.H"
    #include "createMesh.H"

I just include these headers, actually I did not use mesh class and time class. It shows a strange problem.

Code:

    Info<<endl;
    //- Check if its realizable, if not, get out of the loop
    if(!gaussian.gaussianCheckRealizable(weights, abscissas, ms, n) )
    {
         break;
    }
    Info<<endl;

See this Info? I have to include this "Info" there. There is no problem with this.

But if I delete this info lines it shows:

Code:

Create time

Constructing single cell mesh

Reading EQMOM properties

#0  Foam::error::printStack(Foam::Ostream&) at ~/OpenFOAM/OpenFOAM-2.2.x/src/OSspecific/POSIX/printStack.C:221
#1  Foam::sigFpe::sigHandler(int) at ~/OpenFOAM/OpenFOAM-2.2.x/src/OSspecific/POSIX/signals/sigFpe.C:117
#2   in "/lib/x86_64-linux-gnu/libc.so.6"
#3  KDF::gaussianCheckRealizable(double const*, double const*, double const*, int const&) at ~/case/phdCase/EQMOM/KDF/KDF.C:113 (discriminator 2)
#4  
 at ~/case/phdCase/EQMOM/EQMOM/EQMOM.C:45
#5  __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6"
#6  
 at ??:?

So Im quite confused now. Adding Info, succeed, Delete Info, fail.
The code is related with Info????

Sorry, the title of this thread is misleading..

Quick answer:

Let me know what title you prefer for the thread and I'll change it.
If you didn't forget to describe anything, then my guess is that the use of "Info" ensures that the necessary libraries are loaded up and ready to go. No using it leads to the libraries being only loaded onto memory, but possibly not initialized.

If you could provide a complete example package, it would make it easier to diagnose.
