= Building the drivers =

The original build instructions are at
[http://svn.netlabs.org/repos/uniaud/GPL/trunk/howtobuild.txt]

The new build instructions are here.

== Install !OpenWatcom ==

The first thing you need to do is install [http://www.openwatcom.org/ OpenWatcom] 1.7a or higher.  You need to install at least the 16-bit and 32-bit OS/2 targets.  It is assumed that you will be installing the OS/2 hosted version of  Open Watcom.

== Install OS/2 Developer's Toolkit ==

This contains alp, needed for the assembly portions. It is included on the eComStation CD.

== Install the DDK ==

If you are going to build uniaud16, you need to install the IBM Driver Development Kit (DDK) Toolkit.  IBM no longer makes this toolkit publicly available.  The long term plan is to implement open source versions of the DDK headers in !OpenWatcom and this will eliminate the need for the DDK to build Uniaud.

== Install ilink or lxlite ==

Either ilink or wlink can be used, but when using wlink, lxlite is required to shrink the binary to a reasonable size.

== Install ACPI Toolkit ==

If building with ACPI support, the [http://en.ecomstation.ru/projects/developer/?action=acpi ACPI developer toolkit] is required.

== Configure the build environment ==

Now you need to build Makefile.inc.  This file configures the uniaud makefiles for your specific directory layout.  Assuming directory layout described in [WikiStart#Gettingthesources Getting the sources], run

== Build uniaud32 ==

{{{
cd uniaud32_workspace\trunk
configure
}}}

and answer the questions.

To build uniaud32, do whatever you do that make the !OpenWatcom available in the current command line session and then

{{{
!m_kee.cmd
}}}

!m_kee.cmd is a simple wmake front-end.

A full build should take less than 15? minutes on reasonably capable hardware and should complete without errors or warnings.

It is considered bad practice to commit sources that do not build error and warning free to the subversion repository.  However, when multiple developers are making concurrent changes, this can happen.

== Build uniaud16 ==


To build uniaud16

{{{
cd uniaud16_workspace\trunk
wmake drv
}}}

A full build should take less than 5? minutes on reasonably capable hardware and should complete without errors or warnings
