Re: Smsd Bug ?

[Raphael Bellec]

Sory for the delay,
Here are the elements :
libmysql client version is the last version in "stable" debian, which is 
3.22.30-4
mysql itself is not on this computer.
the error msg is 

Erreur dlopen : /usr/local/stow/gnokii//share/smsd/libmysql.so: undefined 
symbol: mysql_real_escape_string
Cannot load database module mysql in directory 
/usr/local/stow/gnokii//share/smsd

I did not have time to investigate more, tell me if you need more information, 
I should have more time this week.
Thanks for the options I missed in the info files.
Regards.

Raphaël.
