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
