I'm trying to use easy_install to install MySQL-python. It fails almost immediately:

_mysql.c:36:23: error: my_config.h: No such file or directory
_mysql.c:38:19: error: mysql.h: No such file or directory
_mysql.c:39:26: error: mysqld_error.h: No such file or directory
_mysql.c:40:20: error: errmsg.h: No such file or directory

It can't find the headers. I have the headers installed, they're just installed from source in /opt. It's obviously not looking there. How do I make it look there? For example, if this was configure, I could do something like "--with-mysql=/opt/mysql". It doesn't appear there is such an option with easy_install. Still researching so if I find my answer I'll post it here.

This looks more like an issue with the compiler search path than a easy_install issu.

Setting the include path environment variable before the easy_install call may work.

C_INCLUDE_PATH=/path/to/your/mysql/include/files easy_install intall MySQL-python

If that doesn't work, try setting the INCLUDE_PATH or CPLUS_INCLUDE_PATH variables. There wasn't enough easy_install output in the question to tell what compiler is being used.

  • I wonder why easy_install/pip don't honor my INCLUDE_PATH env var. Thanks for the post. – D. A. Mar 07 '13 at 14:44
  • This solution did not work for me. Instead I was able to get past the error by installing pkg-config (sudo apt-get install pkg-config) – taranaki Jul 15 '15 at 20:01

easy_install invokes setup.py, which will respect a setup.cfg file in the distribution it's trying to install. Although you cannot specify the setup.py options --include_dirs and --library_dirs directly to easy_install, you can put them in the setup.cfg file.

I have a similar issue with pysqlite: I put SQLite in a non-standard location, and wanted to use easy_install to get the Python bindings. The pysqlite distribution includes a setup.cfg file with sample include_dirs and library_dirs directives, so it was clear what to do.

If MySQL-python has a setup.cfg file, you could try adding / editing it to include:

[build_ext]
include_dirs = /path/to/headers
library_dirs = /path/to/libs

If there's already a [build_ext] section in the setup.cfg file, add to it instead of creating a second one.
