rheolef-config(1rheolef) rheolef-config(1rheolef)

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.
