This error broke my python-mysql installation on Mac 10.7.5. Here are the steps
- The installed python is 2.7.1, mysql is 64 bit for 5.6.11.
- The being installed python-mysql is 1.2.4, also tried 1.2.3
Configurations for the installation
1) sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql 2) Edit the setup_posix.py and change the following mysql_config.path = "mysql_config" to mysql_config.path = "/usr/local/mysql/bin/mysql_config" 3) sudo python setup.py build
Here is the stacktrace for build

Welcome your suggestions and ideas. Thanks.

Try to Remove cflags -Wno-null-conversion -Wno-unused-private-field in
/usr/local/mysql/bin/mysql_config.
like:
cflags="-I$pkgincludedir -Wall -Os -g -fno-strict-aliasing -DDBUG_OFF -arch x86_64 " #note: end space!

Wow, I've been spending a couple of hours on thistrying to 'pip install MySQL-python'. I have been re-installing Xcode 4.6.3, the Xcode command line tools seperatly (on Mac OS X 10.7.5), and installing Kenneth Reitz' stuff (https://github.com/kennethreitz/osx-gcc-installer) to no avail while I was ...
Altering the cflags options finally helped!
Thanks!
