============================================================= | ||
Using the Simple DirectMedia Layer with OpenBSD 2.9 and later | ||
============================================================= | ||

There is an OpenBSD port for SDL and various other tools. Using | ||
this port is recommended, since it contains all the needed patches | ||
and configure arguments nicely organized in several FLAVORS you | ||
can pick from. If you're unfamiliar with the OpenBSD ports system | ||
please visit: | ||
http://www.openbsd.org/ports.html | ||
http://www.openbsd.org/anoncvs.html | ||
|
||
You should have a precompiled binary package on your OpenBSD 2.9 | ||
or later CD-ROM, which you can easily add with pkg_add(1). | ||
|
||
If for whatever reason you're unable to take the advantage of the | ||
created port, or you want to stick with the newest fresh SDL from | ||
the current CVS repository, here are some hints of what has left | ||
unresolved and needs to be disabled/changed. | ||
|
||
To build SDL with OSS + esound: | ||
|
||
1. ./configure --disable-joystick \ | ||
--disable-pthread-sem \ | ||
--disable-nasm \ | ||
--enable-esd \ | ||
--enable-oss \ | ||
--disable-arts \ | ||
--disable-video-opengl | ||
|
||
OR | ||
|
||
To build SDL with native audio + esound (remove --disable-esd otherwise): | ||
1. ./configure --disable-joystick \ | ||
--disable-pthread-sem \ | ||
--disable-nasm \ | ||
--enable-openbsdaudio \ | ||
--enable-esd \ | ||
--disable-arts \ | ||
--disable-video-opengl | ||
|
||
If you need arts or GL, omit the responding --disable lines. In the | ||
port, they're disabled by default, you need to specify flavors to | ||
make use of them. | ||
|
||
2. gmake # Yeah, GNU make is required, install the package | ||
3. sudo gmake install | ||
|
||
========= | ||
Todo List | ||
========= | ||
|
||
Feedback is always welcome with anything you may find useful and | ||
you can suggest. | ||
For now, the following things have to be worked on: | ||
|
||
1. The native audio should be widely tested and will eventually | ||
become the default. At that moment I have not received any | ||
feedback which should explain its current condition. | ||
|
||
2. There are occurences of dynamic loading of drivers in the OpenGL | ||
code section, and our a.out architectures need an underscore prefixed | ||
to symbol names. Some solution to that may be a good thing. I can | ||
fix it theoretically, but unfortunately I do not have the needed | ||
hardware/configuration to test it. If you bump into that, email me. | ||
|
