Comment 8 for bug 240519

Solution:

Ok... so I installed the php5 source package

apt-get source php5

I decided to just give the extension in ext/sybase a try before applying any patches.

cd ext/sybase
phpize && configure && make && sudo make install

After that it was a simple matter of adding a sybase.ini file to /etc/php5/conf.d with the contents

extension=sybase.so

I then restarted apache2 and it works :)

I'm still a bit confused as to why the php5-sybase package installs the mssql.so module, and the php5-mssql package is a virtual for php5-sybase. But it is working for me now, and hopefully the people who need this info can find it here.

Thanks again for the help Ondřej and Chuck!
