clang: error when allmake about openfoam-os-x HOT 5 CLOSED

Hi,

I can confirm, the error. It happens during compilation of geompack.C. And it seems, there is a problem with compiler flags, as without flags file is compiled without problem.

from openfoam-os-x.

Possible work-around is to add #pragma clang fp exceptions(ignore) at the top of triSurface/triSurfaceTools/geompack/geompack.C. This will switch off trapping math for this file.

Thank u for your advice!
It's not cause by the goepack.c . It's problem of the Xcode. After I change the Xcode 13.x to 12.5, everything is done. :)

It is a problem of clang 13.1.6 not being able to compile geompack.C with -O3 and -ftrapping-math flags. So, using #pragma clang fp exceptions(ignore), I switch off -ftrapping-math flag for geompack.C, which fixes the problem of compilation.

Yes, you can also switch compilers. Though, adding a line to a file seems to be simpler, than downgrading of Xcode.

OK. I got it.
THANKS!
