Re: ZODB won't install into Virtual Environments on OSX

Hello Jason,

I see you have a different version of Xcode installed, so I upgraded my version of Xcode but installing ZODB still fails.

I see you unset various C related environment variables, but could you check your environment for any Python related variables or things like DYLD_LIBRARY_PATH etc?

My system include files clearly are the same as both you and Jim, yet ZODB fails to locate stdio.h

My current guess is somehow the ZODB installer does not pick up the system include files or resets them and looks for some sort of environment variable, perhaps something Homebrew relies upon.

Thanks!
