There are a number of options available when choosing tools to build an Apache
module for MPE/iX. Some of these tools are open source tools from the GNU
Project, a provider of free software. The GNU tools are used on many operating
system platforms for development of open source code, including MPE/iX.
Module compilations on MPE/iX can be done with the GNU C compiler, gcc,
or with the MPE/iX POSIX compiler, c89. HP recommends using gcc
for compiling open source modules since most open source code is designed for
compilation by gcc. For example, Apache for MPE/iX is compiled with
gcc. Use c89 when calling MPE/iX intrinsics or using long
pointers.
When using a Makefile to build a module, it can be executed with
GNU make or with the MPE/iX POSIX make. GNU make is
recommended for executing a Makefile created by apxs since this
file is generated by open source code. The GNU tools' installation script
installs GNU make in /usr/local/bin/make. MPE/iX make
resides in /bin/make.
Modules can be lined with GNU ld or with the MPE/iX LinkEditor.
HP recommends using LinkEditor for linking Apache modules since the
LinkEditor creates shared libraries that work well with dynamic loading.
Make, gcc, and ld are part of the GNU tools which are
downloadable from http://jazz.external.hp.com/src/gnu/gnuframe.html.
Support contracts for gcc are available from
http://www.gccsupport.com. LinkEditor, c89 and
/bin/make are supported by HP.
The Apache C header files are required when compiling an Apache
module. These header files are distributed with the Apache product
and reside in /APACHE/PUB/include.
