Building lxml with mac os x mountain lion fails.
Hello, I'm trying to build lxml on mac os x 10.8 and the build fails. I've also tried to change the compiler from gcc to clang, and it still fails. Output: http://paste.ubuntu.com/1172867/ (this is the output when CC=clang) any ideas? =/ ~mark

Doesn't work =/ I did export LIBXML2_VERSION=2.8.0, but since i'm on mountain lion, it seems that the script keeps trying to use the wrong sdk, its no longer /Developer/SDKs/MacOSX10.4u.sdk, but /Applications/Xcode.app/Contents/Developer. Also, i've read that xcode no longer supports building ppc binaries, and that was causing the entire build to fail with something like 'lipo: can't figure out the architecture type of: /var/ folders/10/10P5vwX-Ghmkg8s25PMr3E+++TI/-Tmp-//ccZQsHOd.out error: Setup script exited with error: command 'gcc-4.0' failed with exit status 1 ". See http:// stackoverflow.com/a/5806246/975046, the fix listed, having "ARCHFLAGS="-arch i386 -arch x86_64" before 'setup.py build --static-deps" seems to make it compile. The setup scripts should really be updated =/ However, this isn't solving my problem. I've gotten it to compile, but trying to import lxml.etree results in this: Corvidae:~ markgrandi$ python3 Python 3.2.3 (v3.2.3:3d0686d90f55, Apr 10 2012, 11:25:50) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin Type "help", "copyright", "credits" or "license" for more information.

Well, I seem to of figured it out. It seems that libxml2 by default tries to include lzma, but since I recently installed the xz libraries, its probably having some conflict with the static vs not static version of liblzma, so i edited the buildlibxml.py script to pass in a '--without-lzma' option, and that worked. My entire compile process is listed below. The setup script REALLY needs to be updated to work with recent versions of mac os x.....

from lxml import etree x = etree.fromstring('''<note> ... <to> ... Tove ... </to> ... <from> ... Jani ... </from> ... <heading> ... Reminder ... </heading> ... <body> ... Don't forget me this weekend! ... </body> ... </note>'''.encode("utf-8")) x
