Apache2::Build \- Methods for locating and parsing bits of Apache source code
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 2
\& use Apache2::Build ();
\& my $build = Apache2::Build\->new;
\&
\& # rebuild mod_perl with build opts from the previous build
\& % cd modperl\-2.0
\& % perl \-MApache2::Build \-e rebuild
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides methods for locating and parsing bits of Apache
source code.
.PP
Since mod_perl remembers what build options were used to build it, you
can use this knowledge to rebuild it using the same options. Simply
chdir to the mod_perl source directory and run:
.PP
.Vb 2
\&  % cd modperl\-2.0
\&  % perl \-MApache2::Build \-e rebuild
.Ve
.PP
If you want to rebuild not yet installed, but already built mod_perl,
run from its root directory:
.PP
.Vb 1
\&  % perl \-Ilib \-MApache2::Build \-e rebuild
.Ve
.SH "METHODS"
.IX Header "METHODS"
.IP "new" 4
.IX Item "new"
Create an object blessed into the \fBApache2::Build\fR class.
.Sp
.Vb 1
\& my $build = Apache2::Build\->new;
.Ve
.IP "dir" 4
.IX Item "dir"
Top level directory where source files are located.
.Sp
.Vb 2
\& my $dir = $build\->dir;
\& \-d $dir or die "can\*(Aqt stat $dir $!\en";
.Ve
.IP "find" 4
.IX Item "find"
Searches for apache source directories, return a list of those found.
.Sp
Example:
.Sp
.Vb 4
\& for my $dir ($build\->find) {
\&    my $yn = prompt "Configure with $dir ?", "y";
\&    ...
\& }
.Ve
.IP "inc" 4
.IX Item "inc"
Print include paths for MakeMaker's \fB\s-1INC\s0\fR argument to
\&\f(CW\*(C`WriteMakefile\*(C'\fR.
.Sp
Example:
.Sp
.Vb 1
\& use ExtUtils::MakeMaker;
\&
\& use Apache2::Build ();
\&
\& WriteMakefile(
\&     \*(AqNAME\*(Aq    => \*(AqApache2::Module\*(Aq,
\&     \*(AqVERSION\*(Aq => \*(Aq0.01\*(Aq,
\&     \*(AqINC\*(Aq     => Apache2::Build\->new\->inc,
\& );
.Ve
.IP "module_magic_number" 4
.IX Item "module_magic_number"
Return the \fB\s-1MODULE_MAGIC_NUMBER\s0\fR defined in the apache source.
.Sp
Example:
.Sp
.Vb 1
\& my $mmn = $build\->module_magic_number;
.Ve
.IP "httpd_version" 4
.IX Item "httpd_version"
Return the server version.
.Sp
Example:
.Sp
.Vb 1
\& my $v = $build\->httpd_version;
.Ve
.IP "otherldflags" 4
.IX Item "otherldflags"
Return other ld flags for MakeMaker's \fBdynamic_lib\fR argument to
\&\f(CW\*(C`WriteMakefile\*(C'\fR. This might be needed on systems like \s-1AIX\s0 that need
special flags to the linker to be able to reference mod_perl or httpd
symbols.
.Sp
Example:
.Sp
.Vb 1
\& use ExtUtils::MakeMaker;
\&
\& use Apache2::Build ();
\&
\& WriteMakefile(
\&     \*(AqNAME\*(Aq        => \*(AqApache2::Module\*(Aq,
\&     \*(AqVERSION\*(Aq     => \*(Aq0.01\*(Aq, 
\&     \*(AqINC\*(Aq         => Apache2::Build\->new\->inc,
\&     \*(Aqdynamic_lib\*(Aq => {
