How to fix the errors while compiling Python 3.2.0

I am trying to create Python-3.2.0 virtual environment for upgrading my tool. The tool was earlier built with 2.7.15 version. Now I want to upgrade it to Python-3.2.0

These are the steps which I followed on Cent-OS:

(a) Download the Python source code from the official repository cd /tmp wget https://www.python.org/ftp/python/3.2/Python-3.2.tgz tar -xvf Python-3.2 cd Python-3.2

(b) Compile Python with the required flags ./configure --enable-optimizations --enable-shared -- prefix=/opt/python LDFLAGS=-Wl,-rpath=/opt/python/lib sudo make install

I got the following errors:

/usr/bin/install -c python-config /opt/python/bin/python3.2m-config
    rm python-config
    LD_LIBRARY_PATH=/tmp/Python-3.2: ./python -E ./setup.py install \

    Python build finished, but the necessary bits to build these modules were not found:

    To find the necessary bits, look in setup.py in detect_modules() for the module's name.

Solution

  • I want to start by saying that what you're trying to do, is an exercise of futility. Check:

    So:

    1. You're trying to "upgrade" from a version that's going out of support at the end of the year (your particular flavor (v2.7.15) released last year) to a version that has been dead for several years

    2. More: you're attempting v3.2.0 which is the very 1st one of that series

    Quickly searching for your error revealed:

    Now, this may or may not be the cause in your case. If it is, there is a fix, but you won't benefit from it because of #2..

    A couple of ideas:
