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