quote: Originally posted by bfennema I got the executable to build with SDL/SDL_mixer instead of mss32, and sound (at least the sfx) seem to work fine. The only thing I couldn't do a direct mapping of was cdrom volume. I couldn't find a way in SDL to adjust the cdrom volume.

SDL doesn't provide a way to control the volume, so you have to implement an OS-specific routine to do it.

Basically in linux, you do an ioctl on the cdrom device (which just happens to be the 'id' field of the SDL_CD struct) -
You can see how I did it in d2x here:
http://cvs.icculus.org/cgi-bin/view...f?r1=1.4&r2=1.5
Note that this doesn't touch the mixer of your sound card, it changes the volume internally on the drive itself.

Thanks btb, this is great! If you're ever interested in helping out with the linux port, let me know. Right now the work is getting the .cpp files so that g++ can compile them. Stuff like correcting case, fixing decls, ....

I'd love to. I don't see how we can really collaborate without CVS or something though. The EULA for this source code is totally fubar, but I have an idea of how we can do it legally.

Oh, okay. I just read the updated FAQ, and that's pretty much what my idea was: Put it on cvs, but in order to get to the web page which shows the password, you have to click a link confirming that you have acquired a "legal" copy of the source, and agreed to the EULA.

Hi uppi,

check cvs for a fix that worked for me. The problem was in netshell.h. Specifically the action callback in the DestroyAction class.

g++ can give crappy error messages sometimes.

Have you actually got the cvs code to build under linux? I found tons of things that wouldn't compile - that GUID thing above, several function calls with the wrong # of args, stuff like that.

Plus there are so many filenames with the wrong case - I guess it doesn't matter if you have the code on a FAT partition though.

	21-11-2003 01:46									#43

So, I'd like to fix the filename case, but we need to decide on a consistent standard. I think that going with Activision's original intent is the simplest.

It looks like most of the time activision intended to use mixed case (FileName.cpp, etc), but then they got lazy.

Some modules however, it seems they intended to use lowercase only - ui/aui_*, for example.

Well, no we havent got it to compile yet, otherwise we wouldnt be working on it

The makefiles: dbgen.mk Crater.mk fault.mk geometric.mk Plasma1.mk Plasma2.mk ctp.mk and ui.mk _will_ (well _should_) compile for now, the others, especially gfx.mk gs.mk ai.mk robot.mk and net.mk will only compile to a certain point and then exit with error messages, which need to be fixed without breaking to much.

The problem with the filenames with wrong cases was fixed rather _quick_ until now: If a file did not find an include because of case errors, the right filename would be given in that file and the include would happily keep its filename....

BTW: Does anybody know if there is a unix equivalent to "_splitpath" as this function seems to be windows only? (It basically splits up the filename to its components, like Drive, Path, Extension...). If not I guess I'll have to write some replacement code for it.

bfennema said he had an executable built, with SDL for sound... perhaps he simply meant he had built it under windows, and replaced the sound code with SDL.

d2x has a splitpath function:
http://cvs.icculus.org/cgi-bin/view....viewcvs-markup
I don't know how accurate it is, but it works for d2x.

Hi Brad,

Yea, this should be fixed properly. What I have been doing is changing the filenames in code and not renaming the files on disk. So I don't have do cvs delete and cvs add the renamed file (btw, is there a better way to do this?)

I put a script in the linux dir called fixcase.sh to make this a little easier.

Although I agree that calling the filename the same as the class it defines is good style.

	21-11-2003 05:05									#47

I think that if you have access to the cvs repository, you can just rename the files directly, and then it'll be as if it had always been that way. It's been a long time since I tried anything like that though.

Uh oh, I got a problem here...

in gfx/spritesys/Sprite.cpp there are calls of some dirty MS Function called _msize, which returns the size of the allocated memory to a pointer.

A search on the internet with "_msize" and "gcc" mainly returned things like this:

foo = _msize(bar);
/* not portable to gcc */


does anybody know how to replace that function? Or else I'll have to figure out, what memory is allocated and somehow store this in a new variable.

I saw that too. I _think_ we can get away with using the (unsupported, undocumented, unportable) function malloc_usable_size()

i.e. just do:
#ifdef __GNUC__
# define _msize malloc_usable_size
#endif

Erm, this is the linux port thread. Kinda hard to port a game to linux if you're working in windows...Therefore i dont think we need win32 ports of commandline tools or editors. Go post in a windows thread, they might need those tools, or post in this thread and add something constructive.

So were replacing a dirty win32 hack with a dirty glibc hack
Anyway, it compiles and we have to test whether this works. (I have a bad feeling, that there we will need some extensive debugging once we get a binary)

Grrr.. Of course there is a problem with this already. If all enums are now sint32's then operator overloading won't work. ie

Player::FindAgreement(const AGREEMENT_TYPE agreement)

used to work, but now doesn't. I'm going to chnage it to

for now. Ideas??

Probably it is the same library as used in CTP1 and as there is a linux version of CTP1 there should such a file, but I can remember that we found something about it in the internet maybe but I am not sure the source code was also there.

Wow, it's LGPL even. Of course, normally integration of LGPL software would not be possible, since it's incompatible with the ctp2 license... In this case, though, since it's the same library Activision used originally, we wouldn't be actually creating a "derived work".
