Hi, I'm trying to compile libmesh with PGI using the instructions outlined
in http://libmesh.sourceforge.net/installation.php but I'm getting the
following error:
"./include/libmesh/libmesh_augment_std_namespace.h", line 59: error:
function
"std::abs(double)" conflicts with using-declaration of function
"abs(double)"
inline double abs(double a)
Does anyone has a clue of how to solve this?
Well, the code on those lines is actually invalid C++; it appears to
be a workaround for some old PGI compiler that didn't correctly define
std::abs(double). You can probably work around the problem by just
deleting that function definition from
include/base/libmesh_augment_std_namespace.h
Assuming that works, would you let us know exactly what version of PGI
you're using? That way we can make the #ifdef there more specific and
come up with a permanent fix.
Thanks,
