I'm trying to compile Python 2.6.8 on Kubuntu 19.04.

Current system version is Python 2.7.16. See below the error message I receive, during make.

oguz@dikanka:~$ tar -xvzf Python-2.6.8.tgz
oguz@dikanka:~$ cd Python-2.6.8/

oguz@dikanka:~/Python-2.6.8$ ./configure

oguz@dikanka:~/Python-2.6.8$ make

Segmentation fault (core dumped)

I found this python bug to be very similar to my case, but it's a rather old bug :

Here it says, posixmodule fails because resource.h is not detected properly by configure. Similarly in my case, pyconfig.h file's HAVE_SYS_RESOURCE_H line is commented out. I also realized that my c lib headers are not under /usr/include/sys and /usr/include/bits. Instead, I can find them under the following locations :

oguz@dikanka:/usr/include/linux$ find /usr/include -name resource.h

I tried symlinks to x86_64-linux-gnu/sys and x86_64-linux-gnu/bits, but the the issue persists.

Any ideas ? Thanks in advance!

Hi Oguz,

Sadly Python 2.6.8 is not supported anymore

Python 2.6 reached end-of-life in 2013, six years ago, and has not received any non-security bug fixes since 2010.  We strongly recommend thst you migrate to a modern, supported version of Python, if not Python 3.7, then at least Python 2.7 which itself will reach end-of-life in 2020.

Hi Oguz,
You just need to change one line in Include/objimpl.h: replace "long double dummy" by "double dummy". Enjoy!
