使用旧版Python安装numpy RPM

Question

I'm trying to install numpy 1.7 via an RPM on an older Linux machine with Python 2.4. The numpy release notes and the RPM page say it is supposed to be compatible with 2.4 (or <= 2.7), but when I try to install it on the machine with the command

rpm -i /tmp/python-numpy-1.7.0-2.1.i586.rpm

I get a number of missing dependency notes, including:

    libc.so.6(GLIBC_2.11) is needed by python-numpy-1.7.0-2.1.i586
    libc.so.6(GLIBC_2.4) is needed by python-numpy-1.7.0-2.1.i586
    liblapack.so.3 is needed by python-numpy-1.7.0-2.1.i586
    libpython2.7.so.1.0 is needed by python-numpy-1.7.0-2.1.i586
    python >= 2.7 is needed by python-numpy-1.7.0-2.1.i586
    python = 2.7 is needed by python-numpy-1.7.0-2.1.i586
    python(abi) = 2.7 is needed by python-numpy-1.7.0-2.1.i586
    rpmlib(PayloadIsLzma) <= 4.4.6-1 is needed by python-numpy-1.7.0-2.1.i586

So now at least Python 2.7 is needed, rather than up to 2.7. Is this a real discrepancy or am I using rpm incorrectly? I'm used to higher-level Linux package managers that report dependencies correctly and install them automatically, so I'm unsure how to proceed here.

Answer 1

If all the machines have identical versions of Python, glibc, etc., then it would probably be easier to get the numpy source and build it yourself, assuming you have gcc (and perhaps gfortran ) installed, along with dependencies like BLAS and LAPACK. Once it's installed on one machine, you can copy the numpy folder (and any .egg file) from /usr/lib/python2.4/site-packages (or whichever directory) and distribute that around the world. Make sure to create static libraries when you build so you don't need all the dependencies everywhere.

I'd also get numpy 1.7.1, as it fixes some issues with 1.7.0.

Answer 2

Are you sure your distribution does not provide numpy already? It looks like numpy is part of epel .

If for some reason you are unwilling to use the version in the distribution, you're likely going to have to build the RPM yourself. I was able to build 1.7.1 on CentOS 5.7 like so:

sudo yum install rpm-build gcc python-devel
wget 'https://pypi.python.org/packages/source/n/numpy/numpy-1.7.1.tar.gz'
tar -xf numpy-1.7.1.tar.gz 
cd numpy-1.7.1/
python setup.py bdist_rpm
sudo yum localinstall dist/numpy-1.7.1-1.i386.rpm

the generated RPM (in ./dist ) should be useable without rebuilding on all of the machines with similar hardware and OS.
