Hello list,

I just tried to compile igraph-nightly-0.6-2258-20110105.tar.gz on an Ubuntu 10.10 64-bit machine (uname -a = 2.6.35-24-generic #42-Ubuntu SMP Thu Dec 2 02:41:37 UTC 2010 x86_64 GNU/Linux) but after a (maybe) seamless ./configure , make-ing binaries led to a double linker error:

/usr/bin/ld: cannot find -lxml2
/usr/bin/ld: cannot find -lz

I checked for libraries and found them at standard filesystem places:
lrwxrwxrwx 1 root root 16 2010-12-18 14:36 /usr/lib/libxml2.so.2 -> libxml2.so.2.7.7
-rw-r--r-- 1 root root 1364056 2010-11-08 21:15 /usr/lib/libxml2.so.2.7.7


lrwxrwxrwx 1 root root 15 2010-12-18 14:16 /lib/libz.so.1 -> libz.so.
-rw-r--r-- 1 root root 96816 2010-05-17 18:27 /lib/libz.so.

the (very) simple workaround to make make (!) succesfully complete was to ln -s libX.so.Y libX.so and after that I could successfully make check the binaries with only two tests skipped and 155 tests successful.

I don't know if that was my machine/configuration issue or there is some work to do on 0.6 Makefile.

Now I am going to uninstall 0.5.4-3 (installed from ubuntu/launchpad repositories) and make install 0.6 because I need igraph_st_mincut

Many, many thanks to Gabor Csardi & Tamas Nepusz for your very valuable work!
