    29 =head1 NAME

    31 B<rpm-config> - OpenPKG RPM library build utility

    33 =head1 VERSION

    35 OpenPKG RPM RPM_VERSION

    37 =head1 SYNOPSIS

    39 B<rpm-config>

    40 [B<--help>]

    41 [B<--version>]

    42 [B<--cc>]

    43 [B<--cppflags>]

    44 [B<--cflags>]

    45 [B<--ldflags>]

    46 [B<--libs>]

    48 =head1 DESCRIPTION

    50 The B<rpm-config> program is a little helper utility for easy

    51 configuring and building applications based on the OpenPKG RPM library.

    52 It can be used to query the C compiler and linker flags which are

    53 required to correctly compile and link the application against the

    54 RPM library.

    56 =head1 OPTIONS

    58 B<rpm-config> accepts the following options:

    60 =over 4

    62 =item B<--help>

    64 Prints the short usage information.

    66 =item B<--version>

    68 Prints the version number and date of the installed RPM library.

    70 =item B<--cc>

    72 =item B<--cppflags>

    74 Prints the C pre-processor flags (C<-I>) which are needed to compile the

    75 RPM-based application. The output is usually added to the C<CPPFLAGS>

    76 variable of the applications C<Makefile>.

    78 =item B<--cflags>

    80 Prints the C compiler flags which are needed to compile the RPM-based

    81 application. The output is usually added to the C<CFLAGS> variable of the

    82 applications C<Makefile>.

    84 =item B<--ldflags>

    86 Prints the linker flags (C<-L>) which are needed to link the application with

    87 the RPM library. The output is usually added to the C<LDFLAGS> variable of

    88 the applications C<Makefile>.

    90 =item B<--libs>

    92 Prints the library flags (C<-l>) which are needed to link the application with

    93 the RPM library. The output is usually added to the C<LIBS> variable of the

    94 applications C<Makefile>.

    98 =head1 EXAMPLE

   100  CC       = `rpm-config --cc`

   101  CPPFLAGS = `rpm-config --cppflags`

   102  CFLAGS   = `rpm-config --cflags`

   103  LDFLAGS  = `rpm-config --ldflags`

   104  LIBS     = `rpm-config --libs`

   106  all: foo

   108  foo: foo.o

   109      $(CC) $(LDFLAGS) -o foo foo.o $(LIBS)

   111  foo.o: foo.c

   112      $(CC) $(CPPFLAGS) $(CFLAGS) -o foo.o -c foo.c
