Anyone have issues setting up the dev environment?

I'm going a bit crazy, here. I've forked ScummVM to play a bit with alternative controls and graphics tweaks to more fully support the HP Touchpad, but I'm getting hung up on dependencies. Specifically, flac. Flac hasn't had an update in quite awhile, so I'm afraid the newer versions of arm-none-linux-gnueabi-gcc aren't treating it well. On a mac (arm gcc 4.3.3), compiling flac throws me:

Code: Select all

encode.c&#58; In function ‘flac__encode_aif’&#58;
encode.c&#58;607&#58; internal compiler error&#58; Bus error&#58; 10

On Ubuntu (well, Lubuntu, but same thing-- arm gcc 4.3.3 again), nearly the same result:

Code: Select all

encode.c&#58; In function ‘flac__encode_aif’&#58;
encode.c&#58;607&#58; internal compiler error&#58; Segmentation fault

For the curious, line 607 is the closing bracket of the function listed.

Has anyone here successfully set up their webOS development environment for ScummVM? If so, how did Flac go for you and what version of the arm gcc did you use?

Edit: It probably goes without saying, but I'm following the instructions here: http://wiki.scummvm.org/index.php/Compi ... mmVM/WebOS

I'm not sure about the compatibility of FLAC on WebOS... have you tried disabling it? Or do you need it?

I never went the route of trying to disable it, since it's listed as required on the compile guide. I figured that would definitely break

. I can give it a shot, but since it's on the compile guide I can't help but think someone must have had some luck with it. There are a handful of sound libraries that the webOS port doesn't use (but ScummVM itself normally does), so the idea of paring that list down any more is a bit frightening. I don't want to improve controls at the expense of losing compatibility

.

Well, disabling FLAC support isn't as bad as you might think

You just do:

Code: Select all

./configure --disable-flac

and

Code: Select all

make

Ha, not bad at all

. Do you fine gentlemen keep an index of what engines/game versions depend on what sound libraries? I'm cool with going that route as long as it doesn't kill off too many games.

The sound libraries are all optional. Mostly, you need them if you have compressed audio game files using the ScummVM tools to save space. Some engines do require the MP3 and OGG libraries (e.g. sword25's audio is encoded in OGG and some the sound in some mohawk games is encoded in MP2). However, there is no game that I know of that came originally with FLAC audio, and there actually are some ports where FLAC doesn't compile out of the box (the WinCE port comes to mind, for example).

So, to sum up: FLAC is not required in any game, unless you have compressed audio files in FLAC format using the ScummVM tools (as it is the only lossless sound compression scheme supported in ScummVM).

Well excellent, then! Thanks, md5

My compile broke on the libtucker plugin with

Code: Select all

install&#58; illegal option -- t

but I'm sure it's nothing library-related. I'm going to switch over to Linux and hopefully I can get these gestures to stop triggering unintentionally

Thanks for your help!

That error is not related to FLAC, but it looks odd... Which gcc version are you using?

Moving to Linux fixed it. My Mac's gcc was version 4.2.1, arm gcc was 4.3.3. No worries

. My compiled version didn't feel like launching in the emulator, but I'll grapple with that when I get home later. It seems like the big hurdles are covered, though!
