31makeaperl - create a new perl binary from static extensions
32
33=head1 SYNOPSIS
34
35C<makeaperl -l library -m makefile -o target -t tempdir [object_files] [static_extensions] [search_directories]>
36
37=head1 DESCRIPTION
38
39This utility is designed to build new perl binaries from existing
40extensions on the fly. Called without any arguments it produces a new
41binary with the name C<perl> in the current directory. Intermediate
42files are produced in C</tmp>, if that is writeable, else in the
43current directory. The most important intermediate file is a Makefile,
44that is used internally to call C<make>. The new perl binary will consist
45
46The C<-l> switch lets you specify the name of a perl library to be
47linked into the new binary. If you do not specify a library, makeaperl
48writes targets for any C<libperl*.a> it finds in the search path. The
49topmost target will be the one related to C<libperl.a>.
50
51With the C<-m> switch you can provide a name for the Makefile that
52will be written (default C</tmp/Makefile.$$>). Likewise specifies the
53C<-o> switch a name for the perl binary (default C<perl>). The C<-t>
54switch lets you determine, in which directory the intermediate files
55should be stored.
56
57All object files and static extensions following on the command line
58will be linked into the target file. If there are any directories
59specified on the command line, these directories are searched for
60C<*.a> files, and all of the found ones will be linked in, too. If
61there is no directory named, then the contents of $INC[0] are
62searched.
63
64If the command fails, there is currently no other mechanism to adjust
65the behaviour of the program than to alter the generated Makefile and
66run C<make> by hand.
