| 30 | 
 | 
|---|
| 31 | makeaperl - create a new perl binary from static extensions
 | 
|---|
| 32 | 
 | 
|---|
| 33 | =head1 SYNOPSIS
 | 
|---|
| 34 | 
 | 
|---|
| 35 | C<makeaperl -l library -m makefile -o target -t tempdir [object_files] [static_extensions] [search_directories]>
 | 
|---|
| 36 | 
 | 
|---|
| 37 | =head1 DESCRIPTION
 | 
|---|
| 38 | 
 | 
|---|
| 39 | This utility is designed to build new perl binaries from existing
 | 
|---|
| 40 | extensions on the fly. Called without any arguments it produces a new
 | 
|---|
| 41 | binary with the name C<perl> in the current directory. Intermediate
 | 
|---|
| 42 | files are produced in C</tmp>, if that is writeable, else in the
 | 
|---|
| 43 | current directory. The most important intermediate file is a Makefile,
 | 
|---|
| 44 | that is used internally to call C<make>. The new perl binary will consist
 | 
|---|
| 45 | 
 | 
|---|
| 46 | The C<-l> switch lets you specify the name of a perl library to be
 | 
|---|
| 47 | linked into the new binary. If you do not specify a library, makeaperl
 | 
|---|
| 48 | writes targets for any C<libperl*.a> it finds in the search path. The
 | 
|---|
| 49 | topmost target will be the one related to C<libperl.a>.
 | 
|---|
| 50 | 
 | 
|---|
| 51 | With the C<-m> switch you can provide a name for the Makefile that
 | 
|---|
| 52 | will be written (default C</tmp/Makefile.$$>). Likewise specifies the
 | 
|---|
| 53 | C<-o> switch a name for the perl binary (default C<perl>). The C<-t>
 | 
|---|
| 54 | switch lets you determine, in which directory the intermediate files
 | 
|---|
| 55 | should be stored.
 | 
|---|
| 56 | 
 | 
|---|
| 57 | All object files and static extensions following on the command line
 | 
|---|
| 58 | will be linked into the target file. If there are any directories
 | 
|---|
| 59 | specified on the command line, these directories are searched for
 | 
|---|
| 60 | C<*.a> files, and all of the found ones will be linked in, too. If
 | 
|---|
| 61 | there is no directory named, then the contents of $INC[0] are
 | 
|---|
| 62 | searched.
 | 
|---|
| 63 | 
 | 
|---|
| 64 | If the command fails, there is currently no other mechanism to adjust
 | 
|---|
| 65 | the behaviour of the program than to alter the generated Makefile and
 | 
|---|
| 66 | run C<make> by hand.
