Re: [php-maint] php5-mysql in backports.org linked against libmysqlclient14?



<Apologies for duplicate mails>

Hi Christian,

at first, the right place for this mail would be  
backports-users@lists.backports.org.

I tried this first, but it was not possible out of the box.

To link against libmysqlclient12-dev leads me into the following configure 
error (libmysqlclient14-dev and above are recognised):

configure: error: wrong mysql library version or lib not found. Check 
config.log for more information.
make: *** [configure-apache2-stamp] Error 1

Maybe you (or anybody else) can enlight me where is the trouble or what maybe 
a work around.

Thanks and with kind regards, Jan.
