Hi!
on a Ultra5 with Gentoo 2007.0 i have unmasked and installed warzone2100 2.0.6 (which runs fine on x86). I get the following trace almost on startup:

Now, i am trying to recompile with the "splitdebug" feature to see if i get more detailed info... What could be the problem?

I see that ntpl is set by default, could this be the problem?

Its a brand new isntalaltion from the 2007.0 just downloaded last week.

Good news, sort of, is that it is not anything specific to your system. I tried it on an SB1000 with 2006.1 profile and see the same failure. My first reaction is that the failure looks like some sort of endian problem or data packing problem, but I don't have much evidence to support this. I'll play with it a bit, too.

For your information, if you set FEATURES='nostrip' and either build with USE=debug or make sure to add '-g' to your CFLAGS, you will get more information --- it seems to be having trouble loading some image file. I don't know if the .img files are 'endian' or if it is a data alignment problem, or what. If I come up with anything, I'll pass it on. If you figure it out, please post it here --- I have no interest in trying to chase down something you have already fixed. :wink:

It's an endian problem. Add -D__BIG_ENDIAN__ to your CFLAGS and you will get into the game; e.g., on your system,
CFLAGS="-O2 -mcpu=ultrasparc -pipe -D__BIG_ENDIAN__"

Try that, and please post your results. (I tried it and when exiting, ran into a bus error, which means a misaligned address. (This is unfortunately not uncommon on sparc when building programs developed on non-sparc, and is symptomatic of sloppy coding practices (suspect casts).)

The -D__BIG_ENDIAN__ solved the problem. Shuold i add it to my CFLAGS or keep it only for warzone? Is it safe?

Anyway, something else is broken. Now i get this (after a starting anew campaign!):

Code:

willy@ultra5 ~ $ warzone2100
open /dev/[sound/]dsp: No such file or directory
error:      OpenAL Vendor: (null)
OpenAL Version: (null)
OpenAL Renderer: (null)

warzone2100: No such file or directory.

And the gdmp is:

I have posted this on the developers forums, but they have never used a sparc or have any knowledge on it...[/code]
