- Subject: Building Python 3 on old distributions
One question asked at today's glibc BoF at the Cauldron was how hard it
was to build Python 3 on old GNU/Linux distributions, should we require it
for the glibc build.
I tried building Python 3.7.0 on Ubuntu 10.04, as the oldest distribution
I have readily to hand for testing such things. I needed to build libffi
and then could build Python 3.7.0:
./configure --prefix=/scratch/jmyers/python-install CPPFLAGS=-I/scratch/jmyers/python-install/lib/libffi-3.2.1/include LDFLAGS="-L/scratch/jmyers/python-install/lib -Wl,-rpath,/scratch/jmyers/python-install/lib"
The resulting Python does not support the ssl module (OpenSSL is too old
and I didn't try building newer OpenSSL locally). It *does* support
If you want to build glibc on Ubuntu 10.04, you'll also need newer GCC,
newer binutils, and either a newer kernel or to cross-test since the
2.6.32 kernel is too old to test glibc anyway. So I think this is older
than any distribution that is actually sensible for building glibc.
