Hi All,

I wrote a daemon in c. The last time I successfully compiled it was in June of 09.

Now I want to make a change, but the program will not compile. I get the following error:

gcc -O3 -ftree-vectorize -W -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wundef -o mydaemon `mysql_config --cflags` mydaemon.c sha1.c `mysql_config --libs` `curl-config --libs`
/usr/bin/ld: cannot find -lmysqlclient
collect2: ld returned 1 exit status
make: *** [mydaemon] Error 1

I use yum to keep updated and subscribe to Atomic Rocket Turtle for the latest updates. Somehow, one of these updates is causing this issue. I have tried re-installing mysql and mysql-devel, checking /etc/ld.conf and running ldconfig. I have tried various path changes, but no luck.

Here is some info about my system:

Here is what mysql_config comes up with:
mysql_config --libs
-rdynamic -L/usr/lib64/mysql -lmysqlclient -lz -lcrypt -lnsl -lm -L/usr/lib64 -lssl -lcrypto

I have searched the web for 2 days now and have not been able to solve this problem yet. It is very important to me to be able to update my daemon, since it is broken in it's current form. It is part of my new website, and I really need it to work.

Any suggestions would be HIGHLY appreciated and I will try to return the favor.

best regards,
Bill Clark

I notice one thing. I am trying to install the 32 bit msyql-devel, but there is a conflict with the 64 bit version. I thought that maybe this will allow my program to complile. Any ideas?

Error Summary

Hi All,

I had to remove mysql-devel.i386 and then install mysql-devel.x86_64.

And now I can compile my c daemon. NICE!

Thanks to markkuk at the centos forums.
