After upgrading from Ubuntu 10.10 (Maverick Meerkat) to Ubuntu 11.04 (Natty Narwhal), you’ll probably find that if you’re running a Plone 4 buildout where you need to upgrade the Plone version, that compilation of Zope will fail. The output will look something like this:
Getting distribution for 'Zope2==2.12.17'. In file included from src/AccessControl/cAccessControl.c:51:0: include/ExtensionClass/ExtensionClass.h:83:20: fatal error: Python.h: No such file or directory compilation terminated. error: Setup script exited with error: command 'gcc' failed with exit status 1 An error occured when trying to install Zope2 2.12.17. Look above this message for any errors that were output by easy_install.
The reason for this is that the default Python version in Ubuntu 11.04 is now Python 2.7, rather than 2.6 as was previously the case. The message here is telling us our Python development libraries/headers aren’t available, so do this:
sudo apt-get install python2.6-dev
and re-run your buildout. Make sure too that if you’re using Plone 4 that you’re using Python 2.6, as newer versions like 2.7 aren’t supported (yet).Go Top
