NAME

       rheolef-config - get installation directories (rheolef-7.1)

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.
