I'm using violetland-0.2.5, it crashes on game load. Here is some gdb output:

How you install the game? Looks like path /usr/bin/../share/violetland/ don't 
point
to the game resources.

This path is correct. Application build with the following commands:

mkdir build
cd build
cmake \
  -DCMAKE_C_FLAGS:STRING="$SLKCFLAGS" \
  -DCMAKE_CXX_FLAGS:STRING="$SLKCFLAGS" \
  -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_INSTALL_PREFIX=/usr \
  -DLIB_SUFFIX=${LIBDIRSUFFIX} \
  -DMAN_INSTALL_DIR=/usr/man \
  -DSYSCONF_INSTALL_DIR=/etc/kde \
  ..
make -j2 || exit 1
make install DESTDIR=$PKG || exit 1
cd -

Look. The messages:
MusicManager...
        loaded 0 tracks
and
Loading monsters...
Total monsters found: 0
says to us that the program can't load the resources (music files and gfx).

But this message:
Loading weapons...
says to us that the program can open a list of weapons from file weapons.

It is strange.

I think you saw the main menu and have chosen the New Survival entry.

Forming terrain...

I think the terrain gfx couldn't be loaded too.

Now I can suggest to you just to check if you have a symbolic links or 
something in
your paths and to try to install to your home directory, for example.

Meanwhile I will try to reproduce your problem.

Hmm... yes, it seems that your FileUtility.cpp is broken under linux. 
Partial fix for the one of the bugs (readlink() does not append a null byte to 
result):

                m_resPath = m_appPath;

P.S. FileUtility::truncateFullPathToDir could be replaced with the standard 
libgen.h/dirname()

Thanks, I will check this for compatibility to other os. My FileUtility already 
has
many fixes for windows, freebsd and personally for gentoo users. I hoped that I 
have
already finished with it...

Another version of the patch. I can play the game now.

I'm glad that you can play the game now. I've seen description of stat() 
function. It
really has some improvements against previous code (for example, it should 
properly
handle symlinks). But I can't understand how I and many others could play the 
game
without any issues in linux (ubuntu, suse, gentoo) without this patch. And I 
should
check now support of stat() in mac os x that is supported now. By the way, 
thank you
for patch and sorry we couldn't help you with this.

On my system d_type is not equal DT_DIR = 4, d_type value is DT_UNKNOWN = 0, 
that's it. And stat() 
function is described in posix standard, so it should be available everywhere.
