bundle install problem: mysql.h is missing

jaycode picture jaycode · May 7, 2011 · Viewed 27k times · Source

in my mac OSX 10.6 32 bit, I can install mysql2 gem quite easily, but not in mini mac 10.6 64bit server.

I have installed MySQL 5.5.11 in troublesome server, while in my home mac MySQL 5.5.0.m2 Somehow when I run bundle install, in server it tries to install mysql2.0.3.2 while in home mysql2.0.2.6

Please don't tell me to

env ARCHFLAGS="-arch x86_64" sudo gem install mysql2 --version '= 0.2.6' -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

I tried that, doesn't work.

Included /usr/local/mysql/bin in $PATH does not help as well.

I tried all the solutions posted here, but was not lucky. I reinstalled mysql with homebrew a couple of times and still no luck. Then I came across a blog post with a solution.

I edited the mysql_config file in /usr/local/Cellar/mysql/5.6.12/bin and removed the W-compiler options -Wno-null-conversion and -Wno-unused-private-field for cflags and cxxflags.

This solved the problem with gem install mysql2 and bundle install
