[Users] Fwd: [new user][help] Problem during install: libcblas

[Roland Haas]

Hello Arthur,

I do not use arch myself and we do not regularly test on it so I cannot
give a very definitive answer.

The error seems to be in your Cactus executable. Can you please provide
the following information:

* the output of ldd exe/cactus_sim
* the "ini" file whose name starts like the output of
  simfactory/bin/sim whoami 
* the optionlist file mentioned in that ini file (in cfg folder of simfactory/mdb/)
* the file configs/sim/OptionList and
  configs/sim/config-data/make.config.defn
* the content of the file
  configs/sim/bindings/Configuration/Capabilities/make.BLAS.defn
* the content of the file
  configs/sim/bindings/Configuration/Capabilities/make.LAPACK.defn

You can also try and see if you have the pkg-config package installed.
If it is not installed then strange things can happen during
auto-detection of libraries.

For some Linux distros (RedHat derivatives in particular) one has to
use the "module" command to enable libraries (eg MPI) and on some one
has to select a particular alternative (debian based ones, OpenSuSE).

Sometimes one also has to log out and back in after installing packages.

Yours,
Roland
