Hi,

Trying to compile egmesh.cpp and got an error saying M_PI is not defined.
https://github.com/ElmerCSC/elmerfem/bl ... .cpp#L2571

There is FM_PI used. It is defined in egdef.h which is included by egmesh.cpp:

Code: Select all

#ifndef FM_PI
#define FM_PI 3.1415926
#endif

But can't find M_PI defination.

Cheers

Cean

It appears in a couple of equations where pi would make since, perhaps just a typo and it should be FM_PI. Just a guess, not an expert.

This has been fixed for a while.
