Please don't! Who will solve ticket #32768 -- https://trac.sagemath.org/ticket/32768 "centos-7-i386: SIGFPE while building dochtml" with no other information at all. My on topic question (given the power of 2 discussion) is: I'm curious -- what is the situation is with Sage and 32-bit Linux? I ask this because I recently wanted to build a specific Docker image involving 32-bit pypy from source in order to try out pypy,js, and couldn't do it! Support for "32 bit linux distributions" has been shrunk a lot in recent years ago (at least what was required by that Dockerfile), in a way that really surprised me. There's also an amazing project called v86, which runs 32-bit x86 operating systems entirely in your web browser your Web Assembly. https://copy.sh/v86/ (I think this is both amazing and at the same time completely useless for probably anybody reading this.) One of the difficulties for them is lack of support for 32-bit Linux distros. E.g., if you click https://copy.sh/v86/?profile=archlinux you're running 32-bit Arch Linux in your web browser nearly instantly, and it downloads files as needed when you first reference them. But as they explain https://github.com/copy/v86/blob/master/docs/archlinux.md "The last ISO installer version of Archlinux that supports 32-bit is 2017.02.01. Later versions of the archis os don't work on the v86 emulator because the installer only supports x86_64, not x86 anymore. For existing Archlinux installations, updates and patches will be done until somewhere around 2018." -- William -- William (http://wstein.org) -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
