gem install mysql "checking for mysql_query() in -lmysqlclie

I've seen this before but I've forgotten how to solve it.

It appears that I have the mysql client libraries installed:

iono@retro[08:25:55][~/] locate libmysqlclient.so

/usr/lib/mysql3/mysql/libmysqlclient.so

/usr/lib/mysql3/mysql/libmysqlclient.so.10

/usr/lib/mysql3/mysql/libmysqlclient.so.10.0.0

/usr/lib/mysql/libmysqlclient.so

/usr/lib/mysql/libmysqlclient.so.14

/usr/lib/mysql/libmysqlclient.so.10

/usr/lib/mysql/libmysqlclient.so.10.0.0

/usr/lib/mysql/libmysqlclient.so.14.0.0

My LD_LIBRARY_PATH is:

export LD_LIBRARY_PATH=/usr/lib/oracle/10.2.0.4/client64/lib:/usr/lib/mysql/

OS:

Linux XYZ 2.6.18-128.1.6.el5 #1 SMP Tue Mar 24 12:05:57 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

What gives?

Full "gem install mysql" output follows:

ERROR: Error installing mysql:

Gem files will remain installed in /home/iono/packages/gems/gems/mysql-2.7 for inspection.

/home/iono/packages/gems/gems/mysql-2.7 for inspection.

Might give some clues.

I've had this issue before - I'm pretty sure I ended up solving it by installing the mysql-devel package first.

Duh.

This is what worked: cd /home/iono/packages/gems/gems/mysql-2.7 ruby extconf.rb --with-mysql-config=/usr/bin/mysql_config

Thanks for such speedy help!!

For completeness, I then did (as per README.html): make make install

Testing ActiveRecord through mysql now seems to work well.
