Topic: AGS engine Linux port

[xenogia]

Thanks for that.  The games worked under that.  I did notice a few oddities though.  When I quit the game it didn't recover back to my default resolution of 1920x1080.  It just stayed 1280x800.  I'm currently using the latest Nvidia Blob (302.17).  I get this error msg in terminal.

Also I noticed some wierd rendering issues in Blackwell Deception.  All I had the x2 filter in Windowed mode and this is what it looked like.

[JJS]

I pushed a change so that the D3D graphic driver setting is ignored on Linux and Mac (the mobile platforms don't evaluate the configuration file).

E: ^^^ I don't see what is wrong with that screenshot. ^^^

[BigMc]

Thanks JJS!

@xenogia: How is it supposed to look like instead?

[xenogia]

My apologies I forgot to click smooth sprites, stupid me.  The crackling audio occasionally happens on load up, but it easily fixed by reloading Pulseaudio by doing the standard killall pulseaudio and it reloads itself and the issue disappears.

[xenogia]

BTW you have done an amazing job on this port.

[JJS]

I haven't done too much for the Linux port, most of it was already finished by the maintainer of the closed source version. The Debian packaging was also done by BigMc.

[Tea23]

I've noticed a lack of updates to the 64bit branch while main is still going along nicely. Does main compile for 64bit yet (thus rendering the branch more or less obsolete) or is it just lagging behind in taking changes from main?

[BigMc]

It's just lagging behind, but no changes that are important for Linux were added to main since the last merge.

[Tea23]

Just spotted this commit. Is that now the 64bit branch obsoleted? Should I expect native 64bit if I just compile main now?

If that's the case I need to remove the $CARCH check from the Arch package.

[BigMc]

Yes.

I just wanted to you know I was able to compile a 64 bit version of AGS on Fedora 16 without a hitch! I had to install a couple of libraries, but otherwise everything worked flawlessly. I now have an AGS binary that will run Resonance, Gemini Rue, Time Gentlemen, and three other random games from the AGS site.

In fact, the binary has run everything I've thrown at it. Super stoked!!! Good work everyone who had a part in this!

Maybe I spoke too soon. I loaded up the AGD remake of King's Quest I, walked to the second screen and saved the game. Then I tried to load the save and ags crashed and I got this error:

Code: Adventure Game Studio

1. An internal error has occurred. Please note down the following information.

[scottchiefbaker]

I have the same problem with King's Quest II, but I get a different error.

Code: Adventure Game Studio

1. An error has occurred. Please contact the game author for support, as this is likely to be a scripting error and not a bug in AGS.

This looks very much like mistake in game saving/restoring code.
What branch you were building from?
I ask because I had this problem just recently in the 'refactory' branch (that was already fixed though, I think).

[scottchiefbaker]

I'm compiling "main" according to git status. Should I try a different branch? I loaded KQ1 in Wine did a save/load just fine. It's the exact same game data so I think the problem lies in the engine.

[Crimson Wizard]

Should I try a different branch?

No, no, I was asking, just in case. Refactory is still pretty unstable on 64-bit platforms. It's just that the bug sounds familiar.

I think the problem lies in the engine.

Well, that's definitely in the engine, that's what I meant .

[scottchiefbaker]

King's Quest 3, and Resonance save/load just fine. Seems like something is amiss with KQ1 and KQ2.

[Crimson Wizard]

I wish I could build 64-bit windows version, but AFAIK allegro does not support compiling in 64-bit mode under Win (well, that's MSVS problem, not allegro's; probably there's way around this like using different compiler, but I haven't looked much into that yet).
And I am not an experienced Linux user, unfortunately.
I think I may check those games with engine built as 32-bit to see if this is a general fault or only specific to 64-bit engine version.

If I won't have any result, it's JJS's or BigMC's turn then.

EDIT: Nah, KQ1 seem to work fine with win32 build (main branch).

[slapin]

hi, all!

This is what happens with latest main branch hash 15039fef3d25004c6ea65501b6da736c59681ee 0,
with Quest For Glory II remake during load of game, after saving,
I run it under gdb:

When run game under wine, no problem occurs.
Hope that helps,
