## I’ve just switched to Fedora and am trying to do a “gem install mysql”. Right at the beginning, I’m getting the error

## find\_library: checking for mysql\_query() in -lmysqlclient…

- no

## “gcc -o conftest -I. -I/usr/lib/ruby/1.8/i686-linux -I. -I/usr/local/include -g -O2 conftest.c -L’/usr/local/lib’ -Wl,-R’/usr/local/lib’ -L’/usr/lib’ -Wl,-R’/ usr/lib’ -rdynamic -Wl,-export-dynamic -lruby-static -lmysqlclient -ldl -l crypt -lm -lc” conftest.c: In function ‘t’: conftest.c:3: error: ‘mysql\_query’ undeclared (first use in this function)

I’m sure this is something that I need to install in Fedora, but I’m not  
sure which package would have this. Can anyone offer any advice?
