[New-bugs-announce] [issue19389] find_file might return a different directory than the tested file

[Mathieu Virbel]

New submission from Mathieu Virbel:

With Maverick OSX (latest version), there is no /usr/include/zlib.h anymore. If you try to compile Python with -sysroot, it trigger a error message:

error: /usr/include/zlib.h: No such file or directory

The issue is in setup.py, where find_file is checking the existence of a filename, but if the filename has been found in a sysroot, it will return the path _without_ the sysroot.

In this case (zlib), find_file correctly find the zlib.h in /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/zlib.h, but return "/usr/include",  and then the setup.py open '/usr/include/zlib.h', which fail.
