Megaglest on PC-BSD/FreeBSD

[m0ellemeister]

Hi,

for several days i was trying to build Megaglest on my PC-BSD box. PC-BSD is a "Desktop FreeBSD" based on the current production release of FreeBSD (version 8.1 at the moment of writing).

I want to thank GeoVah for is work on the MacOSX port. Without his work i wouldn't be able to compile megaglest successfully on FreeBSD.

I wasn't able to test megaglest test directly after building, anyway i show the output from mg on the terminal:

i'm going to test megaglest tonight when i'm back home.

Excellent and great job!

tomreyn, claymore and me had a short game a few minutes ago. Everything worked fine and smoothly. My PCBSD Box was the host. we played 3.3.7 Beta_2.

Now i'm going to create the patch-set for FreeBSD.

Here is a screenshot from a single player game: (3360x1050x32) http://imagebin.ca/view/jWiPHvmu.html

Here's the patch for platform_common.cpp:

EDIT: made some changes. That way will be (hopefully) proper checked if OS is APPLE or FreeBSD. The first diff i made wasn't usable at all i guess. This one should works.

Despite these patches it's needed to pass some optione to the configure script on FreeBSD. I call the configure script like this:

Code: [Select]

/configure --with-wx-config=/usr/local/bin/wxgtk2u-2.8-config --with-wx-prefix=/usr/local --with-ogg=/usr/local --with-vorbis-includes=/usr/local/include --with-vorbis=/usr/local --with-libLibX11=/usr/local --with-libLibCurl=/usr/local --with-libLibPng=/usr/local --with-libLibJPEG=/usr/local --with-libOpenAL=/usr/local --with-libxerces=/usr/local --prefix=/usr/games
The software dependencies are quit the same like for glest, which is allready ported to FreeBSD. Before you try to build megaglest on FreeBSD it's necessary to install the Buid-Deps. The dependencies can be viewed with the following commands:

Code: [Select]

cd /usr/ports ; make search name=glestThe ports collection must be installed ;-)

I hope these patches are good enough to be added to upstream :-)

If have to rework my patch for platform_common.cpp. It's unusable i guess.

[m0ellemeister]

i've updated the diff files. Now it should be possible to apply the diffs. Please let my know if it works or doesn't. Thx.

[softcoder]

Hello m0ellemeister and thanks for your hard work!

Could you please produce 1 diff file with all changes for me to apply to svn (same as how GeoVah does) as it is more easy to follow the changes and apply the patch.

Thanks

[m0ellemeister]

i'll do it, maybe tonight when i'm back home.

[m0ellemeister]

Hi softcoder,

here's the diff File: http://nichthelfer.de/FreeBSD.diff

md5sum of this file is: 7dbf40ba215cdc8ff390dd0812a6c184

Hopefully that's what you need.

[softcoder]

Ok this patch is now in svn, thanks!
