I'm trying to compile FF 23.01 on Ubuntu 10.04, 64bit.

I get the error: Python 2.7 or greater (but not Python 3) is required to build. You are running Python 2.6.

I need to install the new version of Python without messing up the existing (package manager) version. What is the best way to do this?

Should I compile the new version in /opt? How do I link the FF compiler to the /opt not the system version? Or are there Python binaries I could download and drop in without building a new one?

Also, how does this affect portability of the finished FF binary? If I use a /opt version of Python, will all target machines need an/opt python installed?

Thanks!

2.7.3 is required. Here's the notice for it from gps:

>Just landed in inbound and making its way to a tree near you is the requirement that you use Python 2.7.3 or greater (but >notPython 3) to build the tree. If you see any issues, bug 870420 is responsible.

I build on Ubuntu 12.04, assuming you don't want to update to that version, I would recommend compiling python 2.7.3 or later in /opt and making softlinks to it in /usr/bin/ so it is the default python in your path.

Also, I don't think the portability of your build of FF will be affected by where your python is located during build time.

I've compiled python 2.7.5in /opt/python-2.7.5/. I just need to know how to link it?

AFAIK, it doesn't. Python is only used for the build system.

You can just set PYTHON=/opt/python-2.7.5/whatever/bin/python in your
mozconfig to tell the Firefox build system to use that specific python
version.

Thanks! I'm passed Python and on to a new error. :)

Nick, I think you should try one of following projects:
https://github.com/utahta/pythonbrew - multiple pythons in one shell, like a rvm for ruby, with virtualenv support
https://github.com/yyuu/pyenv - newer without virtualenv support

After installing all required packages for compilation (openssl, bzip dev libs) works like a charm :-)
