NAME

l2-config - OSSP l2 library build utility

VERSION

OSSP l2 0.9.13 (08-Jun-2007)

SYNOPSIS

l2-config [--help] [--version] [--all] [--prefix] [--exec-prefix] [--bindir] [--libdir] [--includedir] [--mandir] [--datadir] [--acdir] [--cflags] [--ldflags] [--libs]

DESCRIPTION

The l2-config program is a little helper utility for easy configuring and building applications based on the l2(3) 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 l2(3) library.

OPTIONS

l2-config accepts the following options:

--help: Prints the short usage information.
--version: Prints the version number and date of the installed l2(3) library.
--all: Forces the output of all flags, that is, including extra flags which are not OSSP l2 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.
--acdir: Prints the installation directory of autoconf data.
--cflags: Prints the C compiler flags which are needed to compile the l2(3)-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 l2(3) 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 l2(3) library. The output is usually added to the "LIBS" variable of the applications "Makefile".

EXAMPLE

 CC      = cc
 CFLAGS  = -O `l2-config --cflags`
 LDFLAGS = `l2-config --ldflags`
 LIBS    = -lm `l2-config --libs`

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