Bitcoin-core team is considering dropping support for 32-bit x86 Linux Bitcoin binaries.
I'm just relaying here in case someone who's not subscribed to the bitcoin-core-dev mailing list is still relying on it.
Quote from
MarcoFalke's mail to the list:
Now that other major software projects and operating systems dropped
support for 32-bit Linux, is there anyone still using the statically
compiled i686 Linux gitian binaries?
None of the developers are running 32-bit Linux on a daily basis, and
testing is getting harder as neither Ubuntu, nor latest Fedora have
32-bit releases of their operating system.
Unless someone requires the gitian binaries, I'd suggest to drop them.
If anyone remains on a 32-bit Linux platform, they can build (and
test!, with `make check` and `./test/functional/test_runner.py`) from
source. This is even possible on systems with less then 1GB of RAM,
