    What is the C++ compiler that you are using? Post the smallest and simplest program that demonstrates the error.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    I am using Linux os with GNU compiler. I am trying to solve injector problem using OpenFoam software. In that i have to add boundary condition for that i have some .C and .H files Here are the files available in this link: Repository - [openfoam-extend] Index of /trunk/Core/OpenFOAM-1.4.1-dev/src/finiteVolume/fields/fvPatchFields/derived/fixedMeanValue

    when i included these files to the standard .C and .H which are available in my computer(standered .C and .H files) and tried to execute it it is showing the following error:

    Find the nearest forum / newsgroup to the source.

    Maybe here

    Several things to bear in mind
    1. They've probably seen it already
    2. They probably know how to fix it in the best way (if they haven't done so already)
    3. They have the most motivation to get it fixed quickly

    Here, you're just taking a blind shot in the dark that someone might just know something.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Post the code for cavitatingFoam.C; if it is like the code here
    OpenFOAM programmer's C++ documentation

    Then I say the cavitatingFoam.C code is VERY poorly written.
    They are using #include from inside the main function; this is really really bad stuff.
