Maybe the game should default to ~/.d2x-xl as the data directory, and keep all the read-only data in /usr/something. I don't see any reason why it should know about all the different pilots present in the machine.

Also, it could complain about all cmdline switches it didn't understand, and somehow ...

Error: Could not set 640x480x32 opengl video mode

This seems to be the problem. What possible causes are there? xrandr gives me valid output with 640x480 included, and glxinfo says that I have OpenGL acceleration.

_sd

Odd thing is, it does not segfault with --enable-debug. I've already done the debugging. The game runs in the loop that waits for the user to pick a pilot. Only problem is that the window is not displayed. Not in my Matrox machine, and not in my GeForce2 machine.

The loop tightens after the first ...

Version 1.6.17, compiled from source in linux, a debug build

When not using printlog or debug, the game runs, consumes some memory, and then segfaults.

With debug, it runs, and requires twice pressing Ctrl+C to get back to console, with no error messages. Relevant portion of d2x.log is:

The machine with the Nvidia GeForce 2 MX is stuck inside newmenu.c:newmenu_get_filename(). It runs all the time, redrawing the menu, but the window is not displayed on screen.

With 1.5.177 .zip sourcecode extracted on top of 1.5.177 .tgz sourcecode, -debug-printlog works. No MEM_FREE_NOMALLOC errors appear in stdout, but there are exactly 418 of them in d2x.log

The backtrace of the first MEM_FREE_NOMALLOC is identical to the one posted above.

I decided to use --enable-debug until I am able to play d2x-xl with my 2nd machine and its GeForce 2 MX.

Do you suggest I forget the MEM_FREE_NOMALLOC and report only segfaults and SDL parachutes? The most recent might need to be reported to SDL or ALSA developers. Or what do you think? If that is ...

linux 1.5.171 with your proposed changes to ogl.c

I'll get 1.5.176 and try it immediately

Update. The shader-related segfault is gone with 1.5.176. The MEM_FREE_NOMALLOC problem is still there, i.e. running ./d2x-gl only gives me about 300 of them and then exit. No d2x-gl window appears at all.

_sd

Now I got 300 times

MEM_FREE_NOMALLOC: An attempt was made to free a ptr that wasn't allocated with mem.h included

and then the game exited. I redirected stderr to a file, and there was one row in the middle of all that said

No, -sdl_mixer 0 or -sdl_mixer 1 do not help. The game exits immediately with both.

-nosound allows to run the game, as do -sound11k and -sound22k. Which, by the way, uses the old menustyle now by default. -sdl_mixer 0 or -sdl_mixer 1 do not cause any problems if I use at least -nosound, -sound11k ...

Is there a way I could get sources for different versions between .150 and .171? Thus I could report where the change happened that causes the crash.

Version 158 crashes with the same 2 lines long message. Regrettably, I don't have any versions between 150 and 158. But meanwhile I could try the ...

Compiled linux version 1.5.171 from source, and running the executable results in:

Fatal signal: Segmentation Fault (SDL Parachute Deployed)
Segmentation fault

Whereas 1.5.150 compiled and run in the same environment, works.

_sd

Here too -sound22k makes the game run (linux 1.5.158 compiled from source), but with old style menus for some odd reason.

_sd

What could I be missing then? In linux, I can run version 137 and 150, but 158 deploys the parachute and segfaults.

_sd

I'm thinking about that right now. Sure I can afford a video card anytime. But it will be 1. second hand and 2. fanless, because I can't justify any costs bigger than that and I want a quiet machine. I am no big gamer, so there was no problem for me in sticking with an old Matrox, especially because ...

I tried the original d2x-gl now. If I cycle through menus on and on, it too eats meory. I'm starting to hate Matrox and the X.org drivers so much.

I can play original d2x-gl in OpenGL mode. Moving the window to stop the flashing works there too. And if I'm using fullscreen, switching virtual ...

Well, this feels a bit silly... the running leak does not happen in the player selection menu, with old menustyle. It happens in the main menu. It does not happen in the mission selection menu, but it does happen in the skill selection menu.

When I, instead of choosing a pilot, run the cursor up ...

The message I wrote to the d2x list was intended to see if anyone else has heard anything about a similar problem, and this far nobody has.

I don't have the memory leak problem with any other game. It doesn't happen with d2x-rebirth, it doesn't happen with original d2x. It doesn't happen with any ...

I'll try to compile d2x-xl tomorrow in an Ubuntu box. I also filed a bug in Freedesktop bugzilla about the memory leak. I still don't get the midi_volume thing. Should I define it or not? Or where is it supposed to come from? Do I have an outdated ALSA, or what else could it be?

If there is no ...

I had \"-player jaakko\" in a file called .d2x-xl in my home dir. Still segfaulted. Tried putting the same string into /usr/local/share/d2x-xl/d2x.ini, with the same result.

Is there an automatic way the game will do this, or will every user need to know to put it there?

_sd

Setting the midi_volume to 4 enables me to compile the game (1.5.132), but when running, I get

The memory hogging allocations are not done through mem.c's mem_malloc. Either some part of the code (probably in font.c) do allocations some other way, or there is a leak in X's drivers or the SDL library.

mem_malloc doesn't get called at all after the pilot selection menu has appeared.

Ok. It took me this night to figure out what is debugging and how to use a debugger. Going to sleep now, and will try that tomorrow. I knew it had to do with the placement of the breakpoints.

I am running a loop in newmenu.c and I have breakpoints at lines 3686, 3693, 3697 and 3731. The allocations happen between 3693 and 3731, both before and after the break at 3697.

Those lines come and go in an infinite loop, until I choose the pilot. Is this the way it should go?

About the memory hog problem. The cause of it is probably not in the menu code. Whereas displaying the in-game help (by pressing F1) caused a hogging speed of about one megabyte in two seconds, the credits screen (accessible from the main menu) made a record of 22 megabytes per second.

Compiled 1.5.125 source. Went perfectly, no problems.

Then, running the binary, the memory hog problem is still there. This is a part from /proc/6773/smaps (the d2x-gl process):

I ran it as root. It worked, and it is beeeautiful!

Only problem is that while I am in any menu, the memory taken by d2x-xl keeps growing. As soon as I enter the game, the memory usage stays same. But as soon as I exit the game and enter the main menu, the memory usage starts growing again.

Update ...

_sd

The game has write permission to everything in my home directory. The game does not have write permission to /usr/local/share/d2x-xl/ where the datafiles are located. I have no idea where it tries to create the files, because it doesn't tell me anything. The -debug switch only outputs:

Stuck in the way that I have no pilots created yet. So, when d2x-xl asks me to select a pilot, the only possibility is to <CREATE NEW>. I give the pilot my name, and it asks me to pick a controller. I choose KEYBOARD ONLY.

Then I think it should put me to the main menu. Instead, it takes me back to ...

_sd

It worked. I was able to compile it. But now I'm again stuck at the pilot selection screen. This same happens with linux 1.5.121 binary.

_sd

I thought that

#define RENDER2TEXTURE 0

is the 2nd fallback solution. My distro is an up-to-date Gentoo, but my graphics card is only a Matrox G400.

I'll get the 1.5.121 source and then tell what happened.

Edit: Got the exact same results with 1.5.121 source.
