At this time from us, unfortunately nothing recent. I only focus on SGI big-endian systems, as these are still the most widely-available (eBay) MIPS systems that can still compile code within reasonable timeframes on Linux. The Gentoo Embedded team has mipsel3 stages based on uclibc-ng from ~2018 available here: https://gentoo.osuosl.org/experimental/mips/uclibc/mipsel3/ And some uclibc-ng mips32r2 stages, also 2018, here: https://gentoo.osuosl.org/experimental/mips/uclibc/mips32r2/ Unfortunately, our support for more recent uclibc-ng-based builds has fallen off the radar due to lack of upstream uclibc-ng activity. I believe the Embedded team is only focusing on musl libc-based build from now on. There are some unofficial MIPS32 little-endian softfloat stages provided by Manuel Lauss on his website here, albeit from 2018: http://mlau.at/files/mips32-linux/ Last, if you truly need something to work with, I have had luck using the OpenADK project's build system to coax musl-based big-endian rootfs tarballs out of it in the past. It's a very flexible build system and should be capable of also generating mips32r* and little-endian builds as well. It is somewhat fickle, though, so you may have to kludge the build process at times to get it to complete. Depends very heavily on what packages you want to build in. -- Joshua Kinard Gentoo/MIPS kumba@xxxxxxxxxx rsa6144/5C63F4E3F5C6C943 2015-04-27 177C 1972 1FB8 F254 BAD0 3E72 5C63 F4E3 F5C6 C943 "The past tempts us, the present confuses us, the future frightens us.
