Hello,

I have a solver that compiles and runs fine, using the gcc provided with OpenFOAM-1.3.
Now I wanted to add an OFstream, but even simply including OFstream.H at the beginning of my code, as the only change, I get this:

~/OpenFOAM/jung-1.3/incompbuoy_axitest1>wmake

The code is simply this:

#include "fvCFD.H"

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

int main(int argc, char *argv[])
{

# include "OFstream.H"

# include "setRootCase.H"
# include "createTime.H"
# include "createMesh.H"
# include "readEnvironmentalProperties.H"

# include "createFields.H"
# include "initContinuityErrs.H"




//OFstream kinlog("bla");



.... and some more - but, as said, removing the inclusion of OFstream it compiles.

any idea someone ?

Thank you very much !

just found out that including OFstream.H BEFORE fvCFD.H everything is fine.

Dont really understand that, but ...

sorry for bothering ...

I see two mistakes.
1) including a header file within main()
2) fvCFD.H conveniently includes lots of things for you, including adding a "using namespace Foam;" at the end, which likely upsets lot of other header files (not just OFstream.H) that you include after.

it is real problem
 
yes, I also met the same problem. and although it can be fixed just followed the suggestion mentioned in this thread. it becomes uncomfortable, isn't it?
