spring and libpython2.6

[StrangeMan]

Hi there.

I'm trying to run spring on my brand new installed opensuse11.1 32bit system. I installed it using the MojoSetup. The only version of libpython, my system provides is 2.6, but spring requires 2.5, which i cant install, due to dependency reasons. (=> I can not downgrade python). I searched the web for more than 3h and also tried to compile from source. I always come to the point, where i need this libpython2.5.so.1.0.

I have libpython2.6.so.1.0, so i created a symlink, what showed spring a "fake" of libpython2.5.so.1.0. Spring started successfully and i was able to play, but after some minutes, it suddenly crashed (It just closes the window and i'm back on my desktop. That happens during onlineplay and singleplayer). I guess, this is a problem, caused by the faked python library.

So i thought, that compiling from source might solve my problem. But scons and cmake show errors while configuring, because they cant find the python 2.5 includes.

Is there a way to run spring with python 2.6 or do my crashes with the fake version of libpython2.5.so.1.0 depend on other reasons?

Thanks for replies,
StrangeMan

the game itself doesn't use python at all; unitsync (the lobby interface lib) uses it. python 2.6 is a two-line addition and already committed to master, try seeking it in git history and making the change yourself.

the crash is probably unrelated.

[StrangeMan]

So, you think, its better to use the symlinked way? Well, ok, but this would mean, that i have to search for the cause of the crash. I'll try to reproduce it and save the terminal output in a file.

I installed my system today, yesterday i had opensuse 11.0 and everything worked find, including the libpython. I had no crashes, thats why i thinkt this library might cause them.

[StrangeMan]

OK, i played the game again and had a crash. I saved the output of startspring.sh, but it doesn't seem to contain crash-related stuff. I read in some other text files and log files, but none seems to contain anything usable. The game doesn't show any error message. What can i do now?

[imbaczek]

compile with debug info and run spring in gdb. when it crashes, print a backtrace (bt) and post the output.

scons and cmake show errors while configuring, because they cant find the python 2.5 includes.

I can't compile without python2.5

I can't compile

Sorry, but I don't think, my skills are enough to do so.

remove the python dependencies from unitsync.
viewtopic.php?p=319821#p319821

if anyone (probably me) ever gets around to needing unitsync in python, I've already got it covered, and my implementation will be more cross-version :)

ctypes ftw.

Ok, i downloaded the config.py from the link and managed to compile spring, libtorrent for the lobby and the lobby itself. I can play a normal game, but there are still crashes. At the moment i'm recompiling with debug=1. For my crash doesn't seem to be libpython-related anymore, i'll open a new topic.

[StrangeMan]

Ok, i got an helpfull error message:

Code: Select all

rts/System/Platform/Linux/SoLib.cpp:23: SoLib::SoLib: libboost_regex-gcc43-mt-1_35.so.1.35.0: cannot open shared object file: No such file or directory

Program received signal SIGSEGV, Segmentation fault.

lobboost_regex seems to be installed. Where can i find Libboost_regex-gcc43-mt?

[imbaczek]

if you compiled correctly, you should already have it :/

[StrangeMan]

Well, scons configure shows me the missing library, but scons compiled without problems or errors. So i thought, it's ok.

Question: why don't you use the opensuse packages?

[StrangeMan]

@Auswaschbar: Because the lobby was very old, and things didn't work good.

@ imbaczek: Well, sometime libraries are optional...

@ all:
This is, what scons tells me:

Everything seems OK. Run `scons' now to build.
scons: done reading SConscript files.
scons: Building targets ...
scons: Nothing to be done for `configure'.
scons: done building targets.

What is that missing library? I can't find it in my package-manager.

When lobby is too old, you should go and compile the lobby instead.

http://software.opensuse.org/search?q=s ... 3A11.1&p=1 here is the most recent version of spring, including unitsync. But I wonder why there are no i586-packages for springlobby...

[StrangeMan]

[...] managed to compile spring, libtorrent for the lobby and the lobby itself [...]

OK, i installed only the yast-packages fpr spring and used my self compiled lobby. But where is the unitsync library now? Without the path to it, i can't change the spring settings.

Well, I would prefer, to use a self compiled version of spring.
