I gave that ago, but to no avail. I'm at a bit of a loss as to what could be going on.ᐧOn 23 January 2017 at 20:40, Tamas Nepusz <address@hidden> wrote:Hi Andrew,This is weird -- it should not have been able to compile and link the Python interface to igraph without libxml2 at all.You mentioned that you installed python-igraph from pip -- this almost surely means that igraph itself was compiled on your machine locally. The only thing that I can think of right now is that you have libxml2 on your machine but not libxml2-dev; the latter package is needed to _compile_ packages that link to libxml2. So, I would probably try this:- ensure that libxml2-dev and pkg-config are both installed- uninstall python-igraph (either destroy the venv and start from scratch, or run pip uninstall python-igraph)- reinstall python-igraph with "pip install python-igraph"All the best,T.On Mon, Jan 23, 2017 at 11:44 AM, Andrew O'Harney <address@hidden> wrote:______________________________This giveslinux-vdso.so.1 => (0x00007ffdd33b8000)libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f7ce24c5000) libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f7ce2143000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f7ce1f2c000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f7ce1d0f000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f7ce1946000) /lib64/ld-linux-x86-64.so.2 (0x000055e56299f000)I can't see a mention of libxml there. How can I add it and is there a reason it wasn't linked with pip?-Andy_________________
