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