Summary0002074: Compilation failed when WM_LABEL_SIZE=64 is set
DescriptionWhen WM_LABEL_SIZE=64 is set, the following statement failed to compile.

List<int> l(5,0);

The error outputs:

Steps To Reproduce1. source ~/OpenFOAM/OpenFOAM-3.0.1/etc/bashrc WM_LABEL_SIZE=64


3. foamNewApp test && cd test

4. Edit test.C, add the following statement to file: List<int> l(5,0);

Have you tried this:

 List<label> l(5,0);

where "label" which is the standard type for integers in OpenFOAM.

By the way, "scalar" is the standard for "double" or "float".

If you want 32-bit integers, I vaguely remember that it's "int32" in OpenFOAM:

Thank you, wyldckat. I've also tried labelList:

  labelList l(5, 0);

But it returns the same error.

When I use WM_LABEL_SIZE=32, the code compiles successfully.

The presence of the Foam::List<T>::List(InputIterator, InputIterator) constructor often causes problem in 64-bit due to overloading resolution issues. I am considering removing it in OpenFOAM-dev, will let you know.

In the meantime try

List<int> l(label(5), 0);

which should be type-specific enough to help the overloading resolution.

Resolved in OpenFOAM-dev by commit 064d3046b9ed363fd51bfceaecd7ba79429227b4
