After completing the configuration, it's time to build the server by simply calling:
panic% make
The make program first compiles the source files and creates a mod_perl library file. Then, depending on your configuration, this library is either linked with httpd (statically) or not linked at all, allowing you to dynamically load it at runtime.
You should avoid putting the mod_perl source directory inside the Apache source directory, as this confuses the build process. The best choice is to put both source directories under the same parent directory.
All Perl modules that use C extensions must be compiled using the compiler with which your copy of Perl was built.
When you run perl Makefile.PL, a Makefile is created. This Makefile includes the same compilation options that were used to build Perl itself. They are stored in the Config.pm module and can be displayed with the Perl -V command. All these options are reapplied when compiling Perl modules.
If you use a different compiler to build Perl extensions, chances are that the options this compiler uses won't be the same, or they might be interpreted in a completely different way. So the code may not compile, may dump core, or may behave in unexpected ways.
Since Perl, Apache, and third-party modules all work together under mod_perl, it's essential to use the same compiler while building each of the components.
If you compile a non-Perl component separately, you should make sure to use both the same compiler and the same options used to build Perl. You can find much of this information by running perl -V.
The following errors are the ones that frequently occur during the make process when building mod_perl.
This and similar error messages may show up during the make process. Generally it happens when you have a broken Perl installation. If it's installed from a broken rpm or another precompiled binary package, build Perl from source or use another properly built binary package. Run perl -V to learn what version of Perl you are using and other important details.
