[Vala] Problem using Mysql in Vala (Fedora 21): /usr/bin/ld: cannot find -lmysqlclient
Hello,
I tried to use MySQL today with Vala but ran into some Problems. I
searched for some solutions but couldn't fix the issue. I saw a few
threads on the list with a similar problem but it didn't help me.
First I was trying to get
http://www.fromdual.com/mysql-vala-program-example working, now it's
only this short snippet:
using Mysql;
static int main(string[] args) {
Database mysql = new Mysql.Database();
return 0;
}
Problem is that I get this message in return:
valac main.vala --pkg mysql -X -lmysqlclient (im Verzeichnis:
/home/axp/Dokumente/Workspaces/10 Vala/MailServer/src)
main.vala:5.14-5.41: warning: local variable `mysql' declared but
never used
Database mysql = new Mysql.Database();
/usr/bin/ld: cannot find -lmysqlclient
collect2: Fehler: ld gab 1 als Ende-Status zurück
error: cc exited with status 256
Compilation failed: 1 error(s), 1 warning(s)
Kompilierung fehlgeschlagen.
I think that there could be problem with my setup. I've done:
yum install mysql-server
yum install mysql-devel
So the libraries and headers are installed and new.
Compilation with valac -c %f --pkg mysql -X -lmysqlclient is working.
But really creating the little program with valac %f --pkg mysql -X
-lmysqlclient fails.
I thought this could be a nice opportunity to try the mailing list. I
hope the problem is not too trivial and I'm the only one who doesn't
know the solution :B
Thank you in advance!

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

This kind of stuff can be a pain. I've found that I sometimes have to
update my c_include_path to include the new shared libraries. Something
like this:
export C_INCLUDE_PATH=/usr/include/libev

Re: [Vala] Problem using Mysql in Vala (Fedora 21): /usr/bin/ld: cannot find -lmysqlclient
Thanks for the answers!
@ Steven Oliver: Am I correct when I say that this solution helps to
find missing header files? I think that they are already correctly found
and the problem lies with the .so file which is not found.
@ Tarnyko: I actually searched for this file before and found it in the
//usr/lib64/mysql/ which is also shown when I use mysql_config. So this
file is /there/ but ... How would I tell valac where the file is?
This kind of stuff can be a pain.
Very true :D
