I cant find the solution, I install and change package versions and I always get the same error.
Could you put me in the correct way?

I am using Ubuntu 9.1, and PokerTh 0.7.1

I get this error:

lib/libpokerth_lib.a(clientstate.o): In function
`boost::iostreams::detail::zlib_decompressor_impl<std::allocator<char> >::filter(char const*&,
char const*, char*&, char*, bool)':

I am on it since thursday... I am really stuck

Which version of boost do you use, then?
You need a very recent version, see here:

I'm often confused about the version numbers vs. the naming of Ubuntu releases.
Does a normal install (via the Ubuntu repos or via the repo that can be found via Download) work?

ohh.. Thanks for your quick response!

Yes, 9.1 is the Ubuntu's release version, and I am able to install and play it from the ubuntu's repository.

The problem is when I try to compile it from Qt IDE. I have tried with the svn release version ( pokerth.svn.sourceforge.net/svnroot/pokerth/trunk/pokerth ?) and with PokerTH-0.7.1-src.tar.bz2 from the download page. I get the same error on both of them, with 1.36, 1.38 or 1.40 boost versions. I have installed the other dependencies as well (zlib 1.2.3, libcurl, gnutls, libSDL_mixer, libSDL, and SASL)

I am not an experienced C++ programmer and I am starting with Qt and linux with PokerTh. I will apreciate if you can advise me how to make it works.

In the following thread they are talking about compile boost libraries with zlib support: www.pokerth.net/index.php?option=com_kun...15&catid=17#3918

Do you think the problem might come from this?

Thanks in advance
