Problems IFstream.H in OpenFoam-2.1.0
I have OpenFoam2.1.0 installed on Mac OS X.
I tried to read and write a text file to get a special parameter
and save some output. Whenever I include either of header files
IFstream.H, OFstream.H, or stream.h on my application I get
compilation errors.

Here is the output message:
------------------Begin of included text ------------------------------

I saw some previous posts about similar errors with bits/codecvt.h
but I could not find a solution to my problem.
I believe the problem resides in some environment variables that are not
properly set in my system.

Did anyone had similar problem ? Any clue in how to fix it?

Thanks in advance.

Greetings Murilo and welcome to the forum!

You can check the following test application for ideas (these commands will build it as well):

cd applications/test/parallel

The resulting application is named Test-parallel.

If it builds successfully, then you can compare how that application works versus the one you're developing!

Best regards,

Thanks Bruno,

I just figured out, doing some try and error tests that the problem I had was related to
the place where I put the #include <fstream> line.
The solution: If I insert it outside the main code I get no problem.
Thanks a lot for your reply.
