Compile error on arm/zaurus

[Glaive]

Hi all!

 

I'm trying to compile gemrb on a zaurus sl-c3100 that is running pdaxrom beta4 with 2.6.16 kernel and have ran into an error. Configure went successfully, but when make is compiling map.cpp I get the following error:

 

Map.cpp: In function `void InitSpawnGroups()':

Map.cpp:122: warning: cast from `char (*)[9]' to `ieDword*' increases required alignment of target type

Map.cpp:124: warning: cast from `char (*)[9]' to `ieDword*' increases required alignment of target type

Map.cpp: In member function `void Map::SpawnCreature(Point&, char*, int)':

make[4]: *** [Map.lo] Error 1

make[1]: *** [all-recursive] Error 1

make: *** [all] Error 2

 

 

Any help would be greatly appreciated!

Yeah, i knew the trick i used there will cause problem with alignment sensitive machines

I'll rewrite spawngroup handling.

Alternatively, you can turn off warnings blocking the compilation, hopefully it won't crash the game, if it crashes, you'll know what is the cause.

 

[edit]

btw, you use an old version. If you can use the CVS on SF, do so!

[Avenger]

Ok, i've rewritten those parts causing problems, but you'll need to download the CVS version or wait for a release, which might be months.

Hi! Wow, that was a fast response!

I'm trying to compile the new version from cvs but still get a similiar error:

[Avenger]

Yeah, it is similar, but in another place, so i take it as an improvement, hehe.

The problem is that my previous fix isn't correct, yet.

[Avenger]

k, it should be good now.

Awesome! Good luck with this, there is a proper ALSA sound device in the newer roms for the Zaurus so the problems I had with nullsound are gone.

Found another one

BTW, you said there's a way to disable such errors. Could you point out how that is done?

Thanks!

[Avenger]

Removing -Werror can help.

 

[edit]

Though i think i only mentioned that i'll fix the errors.

It could be that some machines would crash or degrade performance when these warnings are ignored, nevertheless you can try to remove the -Werror option.

Unfortunately that didn't help because after removing -Werror from the makefile g++ segfaulted while compiling SDLVideoDriver.cpp

 

Thanks anyway!

[Avenger]

What? g++ segfaulted?

That is definitely not a gemrb fault. Try again with a clean remake.

If it still segfaults, hmm, then there is a severe bug in g++ which you should report.

Sadly this problem is not easy to fix, we already discussed it in the team.
