rheolef-config(1) get installation directories


The following command returns the rheolef libraries directory:

        rheolef-config --libdir

An environment sanity check writes:

        rheolef-config --check


This command is usefull when linking executables with rheolef: libraries locations are required by the link editor. Such directories are defined while configuring rheolef, before to compile and install see .Installing}'. The rheolef-config command returns these settings.

Note that rheolef-config could be used in Makefiles for the determination of linker flags.

Another usefull feature is the --check option. When rheolef is installed in a user directory, i.e. not as root, the sane run-time environment depends upon two environment variables. The first one is the PATH: bkindir directory may be present in PATH. The second environment variable is related to shared libraries, and its name is system-dependent, e.g. LD_LIBRARY_PATH on most platforms and SHLIB_PATH on HP-UX. Its content may contains bindir.

        rheolef-config --shlibpath-var

Since it is a common mistake to have incorrect values for these variable, for novice users or for adanced ones, especialy when dealing with several installed versions, the environment sanity check writes:

        rheolef-config --check

If there is mistakes, a hint is suggested to fix it and the return status is 1. Instead, the return status is 0.


rheolef version.
print option summary and exit.
install architecture-independent files location.
architecture-dependent files location.

object code libraries directory.
read-only architecture-independent data location.
read-only architecture-independent data location; specific for package.

true or false: whether it is the distributed version.
returns the rheolef Float type. Float is double by defaut. It could also be an extended arithmetic precision type as dd_real (quadruple precisio or qd_real (octuple precision), depending on the configure option at compile time.
true or false: whether it is the new/old code branch that is installed.
