Bugzilla Bug 114871

smac/smacx/smacpack/smac.dynamic/smacx.dynamic all immediately segfault on my
system. strace's also immediately segfault. The only way to get it working is to
use the following command:

LD_PRELOAD=/usr/lib/loki_libsmpeg-0.4.so.0 /opt/smac/smac.dynamic

which then runs smac with no problems. The /usr/games/bin/smac* wrappers may
need to be changed, depending on how specific this problem is to my system

correction, the game starts fine but crashes when the actual gameplay starts
with:
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  66 (X_PolySegment)
  Serial number of failed request:  2854
  Current serial number in output stream:  2857

adding SDL_VIDEO_YUV_HWACCEL=0 to the command only delays the crash, with the
same error message (but different last two numbers)

try building smpeg with USE=-mmx please

no change. Crash as soon as gameplay starts with LD_PRELOAD, crash about half a
minute into gameplay with LD_PRELOAD and SDL_VIDEO_YUV_HWACCEL.

btw, I'm specifying the lib-compat-loki smpeg lib on the LD_PRELOAD line, not
the smpeg package lib

Are you trying to run the game directly from /opt/smac? That won't work, that's
what the wrapper scripts in /usr/games/bin are for.

thats just it - the wrapper scripts dont work:

simon@wh-448-smc78 ~ $ /usr/games/bin/smac
Segmentation fault
simon@wh-448-smc78 ~ $ /usr/games/bin/smacx
Segmentation fault
simon@wh-448-smc78 ~ $ strace /usr/games/bin/smac
Segmentation fault
simon@wh-448-smc78 ~ $ strace /usr/games/bin/smacx
Segmentation fault

I am having no such issues myself.  I just updated the version of smac in the
tree.  Can you verify that this is not resolved with the newest ebuild?

(wait ~1 hour then emerge sync)

I just installed this and it is working flawlessly for me, so I cannot replicate
your issue.

re-emerging smac fails with the following:

with no errors above that

Alright... apparently the loki_patch update caused some issues.  I have masked
the newer version of loki_patch, so if you could downgrade your version and try
again, I'd be appreciative.

nope, same problem (segfaults) 
loki_patch-20050324  
smac-6.0a

Created an attachment (id=75233) [details]
strace smac output

but 'strace smac[x]' produces the following output

This problem is caused by CFLAGS. I was able to fix it by using safe Cflags
from gentoo wiki

nevermind the crash came up again but only happened after video of pod crashing

thats the same place that crashed usingn LD_PRELOAD and smac.dynamic with me.
Its unlikely to be a cflags problem, since all the libraries and binaries used
are precompiled

I noticed we both are using ~x86 version of glibc could this be causing
segfault?

/etc/portage/package.keywords:
  sys-devel/gcc
  sys-devel/gcc-config
  sys-libs/libstdc++-v3
  sys-libs/glibc

  media-video/nvidia-kernel
  media-video/nvidia-glx
  media-video/nvidia-settings
  x11-base/opengl-update
  x11-base/xorg-x11
  media-sound/nforce-audio

  app-admin/eselect-opengl
  app-admin/eselect
  sys-libs/timezone-data

  games-engines/stratagus
  games-strategy/magnant
  games-strategy/smac

the difference btwn glibc x86 and ~x86 is only a revision but we're both using
xorg-x11 ~x86 so could the segfault be caused by X?

ok i fixed my problem. smac needs depth 8 or 16 set in xorg.conf. i didnt have
this so no wonder it was an invalid parameter attribute :-D.

nope, that doesnt work for me. The problem seems to be in this line of the
strace:
geteuid()                               = -1 ENOSYS (Function not implemented)
which is supplied by glibc I think. Is a precompiled version of the library
this is in provided by the loki_compat ebuild, or is it using the system
library?

try putting this in your xorg.conf . I just undid my fix and tried to recreate
your problem. what I specifically needed is the DefaultDepth 16 . if i didnt
have that or it was set to 24 it wouldnt work. I dont think smac can change
depth properly.

Section "Screen"
    Identifier  "Screen 1"
    Device      "GeForce"
    Monitor     "Generic Monitor"
    DefaultDepth 16
    Subsection "Display"
        Depth       24
        Modes       "1280x1024"
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes       "1280x1024"
    EndSubsection
EndSection

The output error seems to be dealing with X 

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  66 (X_PolySegment)

also im playing the game windowed smac -w . screensize (800x600 i think) might
need to be set also.

that doesnt solve it

I have started getting a new error. Now the game doesn't start up at all, even
with smac.dynamic:
$ LD_LIBRARY_PATH=/opt/smac /opt/smac/smac.dynamic 
/opt/smac/smac.dynamic: error while loading shared libraries:
libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or
directory

There is still the same segfault and strace running the static versions

ah, smac works fine now. The library problem I was having is due to bug 119021,
and changing to 16bit colour makes smac work.

Should have marked this FIXED a long time ago...
