VAR-CONFIG(1)             Variable Expansion Library             VAR-CONFIG(1)


NAME

       var-config - OSSP var library build utility


VERSION

       OSSP var 1.1.3 (02-Oct-2005)


SYNOPSIS

       var-config [--help] [--version] [--all] [--prefix] [--exec-prefix]
       [--bindir] [--libdir] [--includedir] [--mandir] [--datadir] [--acdir]
       [--cflags] [--ldflags] [--libs] [--libs++]


DESCRIPTION

       The var-config program is a little helper utility for easy configuring
       and building applications based on the OSSP var library.  It can be
       used to query the C compiler and linker flags which are required to
       correctly compile and link the application against the OSSP var
       library.


OPTIONS

       var-config accepts the following options:

       --help
           Prints the short usage information.

       --version
           Prints the version number and date of the installed OSSP var
           library.

       --all
           Forces the output of all flags, that is, including extra flags
           which are not OSSP var specific.

       --prefix
           Prints the installation prefix of architecture independent files

       --exec-prefix
           Prints the installation prefix of architecture dependent files.

       --bindir
           Prints the installation directory of binaries.

       --libdir
           Prints the installation directory of libraries.

       --includedir
           Prints the installation directory of include headers.

       --mandir
           Prints the installation directory of manual pages.

       --datadir
           Prints the installation directory of shared data.

       --cflags
           Prints the C compiler flags which are needed to compile the OSSP
           var based application. The output is usually added to the "CFLAGS"
           variable of the applications "Makefile".

       --ldflags
           Prints the linker flags ("-L") which are needed to link the
           application with the OSSP var library. The output is usually added
           to the "LDFLAGS" variable of the applications "Makefile".

       --libs
           Prints the library flags ("-l") which are needed to link the
           application with the C OSSP var library. The output is usually
           added to the "LIBS" variable of the applications "Makefile".


EXAMPLE

        CC      = cc
        CFLAGS  = -O `var-config --cflags`
        LDFLAGS = `var-config --ldflags`
        LIBS    = -lm `var-config --libs`

        all: foo
        foo: foo.o
            $(CC) $(LDFLAGS) -o foo foo.o $(LIBS)
        foo.o: foo.c
            $(CC) $(CFLAGS) -c foo.c
