Hello there,

my Mandriva has the 2.6.4 python pre-installed (in /usr/lib64/
python2.6/)
I need to install numpy 1.4 for python 2.4.3 (I installed it
separately from source on/usr/local/lib/python2.4/ )

but still typing "python" I get:
Python 2.6.4 (r264:75706, Jan 8 2010, 18:59:59)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

what to change in order to get "python" calling python 2.4.3 instead
of 2.6.4 (at least during python setup.py build)?

I suppose I need something like changing the link to /usr/local/bin/
python..
but I fear to do something bad by myself..
please help!

Just run the python-2.4 binary.

There will likely be a /usr/bin/python-2.4 or similar.

cheers

That will do bad things to your system, which will be expecting the
system Python to be 2.6 and instead will be 2.4. You will probably find
system tools will start to fail.

Yes, that will do it, but if you do, you will probably break things. Best
to just call the python2.4 binary directly.

If you call

python2.4

from the command line, what happens?

thanks guys,

the solution for me was

python2.4 setup.py install --prefix=/usr/local

cheers, AZ

Don't do that! Like Steven said, you'll kill your system that way.
Lots of programs in Linux use Python and those programs expect
/usr/bin/env python to map to python2.6. Other versions of Python
should be referenced by the version: so python2.4 for Python 2.4,
python3 or python3.1 if you decide to install Python 3.1.
