I run into the following error when compiling on an SGI Altix system (IA-64 processors, linux kernel 2.4.21), using the intel 9.0 compiler:

--------------------------------------------

any idea?

(one suggestion might be "use the gnu compiler", but we are still having trouble installing a more recent version)

thanks in advance.

Try replacing uint64_t with 'unsigned long long' (or anything else which is 64 bit unsigned integer)

Yes, replacing uint64_t with 'unsigned long long' indeed worked.

Thanks!

After the above modification, I finished the compilation of openfoam.

Then I started with the example "icoFoam" from the tutorial, as suggested
in the "README". "blockMesh . cavity" generates a singular "points" file,
as follows:

Any ideas of what is going on?

Possibly your run-time selection tables are not constructed correctly? (compiler issue)

Try running a mesh generated on another machine and see if you get any messages about non-existing boundary conditions.

>Try running a mesh generated on another machine

We did just that (icoFoam-cavity,laplacianFoam; also in parallel using SGI MPT-1.9.1) and it works fine on grids/decompositions generated on a different machine.
