=head1 NAME
|
||
|
|
|
||
|
|
h2ph - convert .h C header files to .ph Perl header files
|
||
|
|
|
||
|
|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
B<h2ph [-d destination directory] [-r | -a] [-l] [headerfiles]>
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
I<h2ph>
|
||
|
|
converts any C header files specified to the corresponding Perl header file
|
||
|
|
format.
|
||
|
|
It is most easily run while in /usr/include:
|
||
|
|
|
||
|
|
cd /usr/include; h2ph * sys/*
|
||
|
|
|
||
|
|
or
|
||
|
|
|
||
|
|
cd /usr/include; h2ph -r -l .
|
||
|
|
|
||
|
|
The output files are placed in the hierarchy rooted at Perl's
|
||
|
|
architecture dependent library directory. You can specify a different
|
||
|
|
hierarchy with a B<-d> switch.
|
||
|
|
|
||
|
|
If run with no arguments, filters standard input to standard output.
|
||
|
|
|
||
|
|
=head1 OPTIONS
|
||
|
|
|
||
|
|
=over 4
|
||
|
|
|
||
|
|
=item -d destination_dir
|
||
|
|
|
||
|
|
Put the resulting B<.ph> files beneath B<destination_dir>, instead of
|
||
|
|
beneath the default Perl library location (C<$Config{'installsitsearch'}>).
|
||
|
|
|
||
|
|
=item -r
|
||
|
|
|
||
|
|
Run recursively; if any of B<headerfiles> are directories, then run I<h2ph>
|
||
|
|
on all files in those directories (and their subdirectories, etc.). B<-r>
|
||
|
|
and B<-a> are mutually exclusive.
|
||
|
|
|
||
|
|
=item -a
|
||
|
|
|
||
|
|
Run automagically; convert B<headerfiles>, as well as any B<.h> files
|
||
|
|
which they include. This option will search for B<.h> files in all
|
||
|
|
directories which your C compiler ordinarily uses. B<-a> and B<-r> are
|
||
|
|
mutually exclusive.
|
||
|
|
|
||
|
|
=item -l
|
||
|
|
|
||
|
|
Symbolic links will be replicated in the destination directory. If B<-l>
|
||
|
|
is not specified, then links are skipped over.
|
||
|
|
|
||
|
|
=item -h
|
||
|
|
|
||
|
|
Put ``hints'' in the .ph files which will help in locating problems with
|
||
|
|
I<h2ph>. In those cases when you B<require> a B<.ph> file containing syntax
|
||
|
|
errors, instead of the cryptic
|
||
|
|
|
||
|
|
[ some error condition ] at (eval mmm) line nnn
|
||
|
|
|
||
|
|
you will see the slightly more helpful
|
||
|
|
|
||
|
|
[ some error condition ] at filename.ph line nnn
|
||
|
|
|
||
|
|
However, the B<.ph> files almost double in size when built using B<-h>.
|
||
|
|
|
||
|
|
=item -D
|
||
|
|
|
||
|
|
Include the code from the B<.h> file as a comment in the B<.ph> file.
|
||
|
|
This is primarily used for debugging I<h2ph>.
|
||
|
|
|
||
|
|
=item -Q
|
||
|
|
|
||
|
|
``Quiet'' mode; don't print out the names of the files being converted.

|
|

|
|
=head1 BUGS
|
||
|
|
|
||
|
|
Doesn't construct the %sizeof array for you.
|
||
|
|
|
||
|
|
It doesn't handle all C constructs, but it does attempt to isolate
|
||
|
|
definitions inside evals so that you can get at the definitions
|
||
|
|
that it can translate.
|
||
|
|
|
||
|
|
It's only intended as a rough tool.
|
||
|
|
You may need to dicker with the files produced.
|
||
|
|
|
||
|
|
Doesn't run with C<use strict>
|
||
|
|
|
||
|
|
You have to run this program by hand; it's not run as part of the Perl
|
||
|
|
installation.
|
||
|
|
|
||
|
|
Doesn't handle complicated expressions built piecemeal, a la:
|
||
|
|
|
||
|
|
enum {
|
||
|
|
FIRST_VALUE,
|
||
|
|
SECOND_VALUE,
|
||
|
|
#ifdef ABC
|
||
|
|
THIRD_VALUE
|
||
|
|
#endif
|
||
|
|
};
|
||
|
|
|
||
|
|
Doesn't necessarily locate all of your C compiler's internally-defined
|
||
|
|
symbols.
