NAME

       rheolef-config - get installation directories (rheolef-7.2)

EXAMPLE

       The following command returns the Rheolef libraries directory:

         rheolef-config --libdir

        An environment sanity check writes:

         rheolef-config --check

DESCRIPTION

       This command is useful 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. The rheolef-config command returns these settings.

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

       Another useful 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: bindir 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, especially 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.

OPTIONS

       --version

            Rheolef version.

       --help

            print option summary and exit.

       --prefix

            install architecture-independent files location.

       --exec-prefix

            architecture-dependent files location.

       --includedir

            include header directory.

       --bindir

            executables directory.

       --mandir

            man documentation directory.

       --libdir

            object code libraries directory.

       --datadir
       --datarootdir

            read-only architecture-independent data location.

       --pkgdatadir

            read-only architecture-independent data location; specific for package.

       --cxx

            compiler invocation (e.g. g++ or clang++).

       --includes

            include compiler flags.

       --libs

            library compiler flags.

       --shlibpath-var

            the shared library path variable.

       --library-interface-version

            the library interface version.

       --hardcode-libdir-flag-spec

            flag to hardcode a libdir into a binary during linking.

       --is-distributed

            true or false: whether it is the distributed version.

       --float

            returns the rheolef Float type. Float is double by default. It could also be an
           extended arithmetic precision type as dd_real (quadruple precision or qd_real (octuple
           precision), depending on the configure option at compile time.

       --have-old-code
       --have-new-code

            true or false: whether it is the new/old code branch that is installed.
