NAME

       rheolef-config -- get installation directories

EXAMPLE

       The following command returns the rheolef libraries directory:

               rheolef-config --libdir

       An environment sanity check writes:

               rheolef-config --check

DESCRIPTION

       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.

FILE 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.

       --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 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.

       --have-old-code

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