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. =head1 OPTIONS B accepts the following options: =over 4 =item B<--help> Prints the short usage information. =item B<--version> Prints the version number and date of the installed l2(3) library. =item B<--all> Forces the output of all flags, that is, including extra flags which are not B specific. =item B<--prefix> Prints the installation prefix of architecture independent files =item B<--exec-prefix> Prints the installation prefix of architecture dependent files. =item B<--bindir> Prints the installation directory of binaries. =item B<--libdir> Prints the installation directory of libraries. =item B<--includedir> Prints the installation directory of include headers. =item B<--mandir> Prints the installation directory of manual pages. =item B<--datadir> Prints the installation directory of shared data. =item B<--acdir> Prints the installation directory of B data. =item B<--cflags> Prints the C compiler flags which are needed to compile the l2(3)-based application. The output is usually added to the C variable of the applications C. =item B<--ldflags> Prints the linker flags (C<-L>) which are needed to link the application with the l2(3) library. The output is usually added to the C variable of the applications C. =item B<--libs> Prints the library flags (C<-l>) which are needed to link the application with the l2(3) library. The output is usually added to the C variable of the applications C. =back =head1 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 =head1 SEE ALSO l2(3), cc(1). =head1 AUTHOR Ralf S.
