Re: [Vala] Problem using Mysql in Vala (Fedora 21): /usr/bin/ld: cannot find -lmysqlclient

[Tarnyko <tarnyko tarnyko net>]

Hi AxP, 

What the message is really telling you, is that you miss the 
"libmysqlclient.so" file. 

This file is typically in a separate package, depending on the distribution 
you are using ; in OpenSUSE for instance, it's in "libmysqlclient-devel" 
(http://rpmfind.net/linux/rpm2html/search.php?query=libmysqlclient-devel) 

Hope this helps. 

Regards,
Tarnyko
