[Users] questions about compilation

[Roland Haas]

Hello Chia Hui Lin,

sorry for the delay, your email got sorted into the wrong folder.

The error that you are seeing (kmpc stuff missing) is usually caused by
a missing OpenMP flags. Please make sure you have:

OPENMP           = yes
CPP_OPENMP_FLAGS = -fopenmp
FPP_OPENMP_FLAGS = -fopenmp
C_OPENMP_FLAGS   = -fopenmp
CXX_OPENMP_FLAGS = -fopenmp
F77_OPENMP_FLAGS = -fopenmp
F90_OPENMP_FLAGS = -fopenmp

in you option list. You can also try and see if 

LDFLAGS = -fopenmp

helps. 

Note that this assumes that your are using the gcc or newer intel
compilers. If you are using an older intel compile then the option is
calles -openmp (no "f") instead.

The utilities are normally not crucial though and you can use Cactus
without them.

Yours,
Roland

> By the way, I commented some module loading in the edison.ini since some of them cannot successfully loaded (maybe because the version of those modules are outdated , and some module even not appear in the module list of edison) . As showed in another screenshot. I am afraid that this caused the occurrence of some error.
