.SH NAME
\fBrheolef-config\fP -- get installation directories
.\" skip: @pindex rheolef-config
.\" skip: @cindex installing
.\" skip: @cindex configure
.\" skip: @cindex Makefile
.SH EXAMPLE

The following command returns the rheolef libraries directory:
.\" begin_example
.Sp
.nf
        rheolef-config --libdir
.Sp
.fi
.\" end_example
An environment sanity check writes:
.\" begin_example
.Sp
.nf
        rheolef-config --check
.Sp
.fi
.\" end_example
.SH 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 .\" REFERENCE Installing}
Installing}'.
The \fBrheolef-config\fP command returns
these settings.
.PP
Note that \fBrheolef-config\fP could be used in Makefiles
for the determination of linker flags.
.PP
.\" skip: @toindex hpux, operating system
Another usefull feature is the \fB--check\fP option.
When \fBrheolef\fP 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: \fBbkindir\fP 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 \fBbindir\fP.
.\" begin_example
.Sp
.nf
        rheolef-config --shlibpath-var
.Sp
.fi
.\" end_example
.\" skip: @cindex environment sanity check writes
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:
.\" begin_example
.Sp
.nf
        rheolef-config --check
.Sp
.fi
.\" end_example
If there is mistakes, a hint is suggested to fix it
and the return status is 1. Instead, the return status is 0.
