Build failing in Mac OS X

[mcandre]

When I try to build mysql-gem in Mac, I get Could not create Makefile due to some reason.

Trace:

$ gem install mysql -v '2.9.1'
Building native extensions.  This could take a while...
ERROR:  Error installing mysql:

@mcandre do you have mysql client library installed in your system? seems mkmf can't find it:

checking for mysql_query() in -lmysqlclient... no
checking for main() in -lm... yes
checking for mysql_query() in -lmysqlclient... no
checking for main() in -lz... yes
checking for mysql_query() in -lmysqlclient... no
checking for main() in -lsocket... no
checking for mysql_query() in -lmysqlclient... no
checking for main() in -lnsl... no
checking for mysql_query() in -lmysqlclient... no
checking for main() in -lmygcc... no
checking for mysql_query() in -lmysqlclient... no

Either you install it with brew or macports, whatever you're using to install dependencies.

[mcandre]

@luislavena Good point. Which Homebrew package would that be?

[luislavena]

@mcandre no idea, I'm not a homebrew user, perhaps mysql-connector-c formula?

[mcandre]

@luislavena brew install mysql-connector-c fixes it on my machine!
