bionic (1) shtool-arx.1.gz

NAME

       shtool-arx - GNU shtool ar(1) extensional command

SYNOPSIS

       shtool arx [-t|--trace] [-C|--command cmd] op archive file [file ...]

DESCRIPTION

       shtool arx is a wrapper around the archiving tool ar(1). It provides the ability to create archives out
       of existing archives, i.e., if one of file matches ""*.a"", the archive member files of file are used
       instead of file itself.

       The trick of this command is the automatic handling of archive members which is especially interesting if
       one wants to construct a (usually top-level) library archive out of pre-built sub-library archives
       (usually staying inside subdirs) in a large source tree. For GNU libtool based projects, a similar
       functionality is provided by GNU libtool internally, too.

OPTIONS

       The following command line options are available.

       -t, --trace
           Shows the actually involved shell commands.

       -C, --command cmd
           Set the used ar(1) command to cmd instead of just "ar" (searched in $PATH).

EXAMPLE

        #   Makefile
        AR=ar
        RANLIB=ranlib
          :
        OBJS=foo.o bar.o
        LIBS=baz/libbaz.a quux/libquux.a
          :
        libfoo.a: $(OBJS) $(LIBS)
            shtool arx -C $(AR) rc libfoo.a $(OBJS) $(LIBS)
            $(RANLIB) libfoo.a

HISTORY

       The GNU shtool arx command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1999
       for GNU shtool. It was prompted by need to build libraries out of sub-libraries inside the OSSP project.
