Exult Forum

Hello,

I want to run exult 1.2 on my AMD64 system with SuSE 9.2 (GCC 3.3.4) as OS.
Calling './configure' seems to work since no error message appears. But if
I call 'make' afterwards, the compilation process stops with an error 'can
not convert xxx to png_int_32 in pngio.cc' or so (I am not sitting on my
private PC right now, so I can not tell you the precise report).
Unfortunately I could not find binaries for my system so I hope anyone of
you can help me to use exult!

This sounds similar to a libpng version problem we've had before. When you're home, could you post the exact error msg?

The error message is:

I thought the problem might be that on x86_64 architectures gcc has 64bit precision for long integers. But other users compiling from source should have discovered such an issue before, shouldn't they?

If you need the full configuration or compilation screen output, email me.

Thanks. I should be able to fix that tonight. If you want to try fixing it locally, look for the "unsigned long w, h;" line just above each error, and change it to "png_uint_32 w, h;".

Ok, I have exult running now!

But at first the compilation stopped with an error anyhow:

Logged in as root I tried the following command:
"ln /usr/lib64/libsmpeg-0.4.so.0.1.4 /usr/lib64/libsmpeg"
and then again
"make"
Now the following error appeared:

So I created the following link hoping that the utf8 Version is OK:
"ln /usr/lib64/libslang-utf8.so.1.4.9 /usr/lib64/libslang.so"
and then again
"make"
Compilation completed now, hence I continued with
"make install"

And after some ~/.exult.cfg editing exult run! The remainig issue was that I had to disable MIDI music otherwise the game crashed - maybe a timidity configuration issue?

So "DrCode", thanks for your patching instruction!

Raphael (glad, playing Ultima again)

Those missing libxxx.so are indication that you haven't installed the development packages for those.

as for the timidity issue, did you take a look at:
http://exult.info/docs.php#linux_alsa

And I still have to remember to fix our code tonight!

Of course I have searched the DVD of my SuSE 9.2 Distribution for libsmpeg.so and libslang.so, but I could only find libsmpeg-0.4.so.0.1.4 and libslang-utf8.so.1.4.9! Hence I created links such as mentioned in my previous post:
"ln /usr/lib64/libsmpeg-0.4.so.0.1.4 /usr/lib64/libsmpeg.so"
"ln /usr/lib64/libslang-utf8.so.1.4.9 /usr/lib64/libslang.so"
And it works!

Timidity runs flawlessly when invoked from the shell e.g.:
"timidity my_favourite_midi.mid". Do I have to create a timidity.cfg file anyway? But I do not mind the non-working midi too much since I downloaded the ogg music files.

If you don't use it, then no, you don't need to create it. But if you want to use midi, yes
