mac snow leopard setuptools stick to MacOSX10.4u.sdk when trying to install python-mysql

Question

when I try to install python-mysql today, I got a number of compilation error or complaining /Developer/SDKs/MacOSX10.4u.sdk not found, like the following:

running build

running build_py

copying MySQLdb/release.py -> build/lib.macosx-10.3-i386-2.6/MySQLdb running build_ext

building '_mysql' extension

Compiling with an SDK that doesn't seem to exist: /Developer/SDKs/MacOSX10.4u.sdk

Please check your Xcode installation

However, I already installed latest xcode 4.0, which does include latest GCC and SDK.

I tried to find out where the 10.4u.sdk is specified, but could not find it in the system environment, program source and setuptools source.

I tried to export

export SDK=/Developer/SDKs/MacOSX10.5.sdk

export SDKROOT=/Developer/SDKs/MacOSX10.5.sdk

but still has no luck.

so anyone has any idea where this is specified in Mac Snow Leopard pls?

thx

Answer 1

Check your environment for CFLAGS or LDFLAGS . Both of these can include the -isysroot argument that influences the SDK selection. The other place to start at is to look at the output of python2.6-config --cflags --ldflags since (I believe) that this influences the Makefile generation. Make sure to run easy_install with --verbose and see if it yields any additional insight.
