Question

Im trying to install shoutpy on opensolaris 2009.6. It relies on boost.python. i ve installed the boost_devel libraries from blastwave and linked /opt/csw/include/boost to /usr/include/boost . But when I try to easy_install shoutpy I get the following output

munderwo@opensolaris-test1:/usr/include$ pfexec easy_install shoutpy

This is using python2.6, opensolaris 2009.06, boost 1.35.

any help would be great!

Cheers

Edit - this has been cross posted on serverfault as its a bit hard to classify where the problem domain is. https://serverfault.com/questions/88724/problem-with-opensolaris-boost-python-and-shoutpy

Answer 1

Unfortunately I ve never tried to compile shoutpy under OpenSolaris and I don t use it these days. Boost.python requires a lot from its C++ compiler. Use easy_install -b build_directory shoutpy so it ll keep the source code after it fails, then check the C++ compiler Python tries to use against those supported by boost.python.

I tried compiling it on my desktop Linux and it still works after I edit setup.py to link against libboost_python-mt instead of libboost_python which doesn t exist in Ubuntu (there are several libboost_python* depending on Python version and so forth).
