Python 2.7 64-bit erroneously refer to 32-bit (x86) for include files

Question

I\'m doing some legacy work with Python 2.7.18 in 64 bit. When PIP calling the compiler (VC for Python), it erroneously refer to 32-bit (x86) sources looking for include files,

Answer 1

As a workaround, I resolved it by calling pip install command with --global-option to specify path of include and lib files. See the example command below:

pip install MySQL-python ^
 --force-reinstall --no-cache-dir ^
 --global-option=build_ext ^
 --global-option="-IC:\my\install\MySQL-x64\MySQL Connector C 6.0.2\include" ^
 --global-option="-LC:\my\install\MySQL-x64\MySQL Connector C 6.0.2\lib\opt" ^
 --verbose

In this example, I have fully installed 64-bit version of MySQL Connector C in customized location of C:\my\install\MySQL-x64\MySQL Connector C 6.0.2\.

I'm still wondering why pip install MySQL-python by default always looks into directory C:\Program Files (x86)\MySQL\MySQL Connector C 6.0.2\, even if you're using 64-bit Python and/or have installed the driver at a different location.

Any additional inputs will be highly appreciated. Or maybe I will post another question ask specifically about the point.
