rheolef-config (1rheolef)

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.
