re-surfacing my own old thread ... On ARM, I was able to do something really simple to obtain complete 32bit development on a 64bit host:
apt install -y build-essential # this install 64bit dev environment apt install -y crossbuild-essential-armhf # this install 32bit cross-dev environment apt install -y libc6:armhf apt install -y libstdc++6:armhf However, similar steps don't work on mips64. Specifically it is apparent crossbuild-essential-mipsel dependency is broken, and if you try to fix the dependencies and it ended up conflicting with build-essential. Are there more better way to install a complete 32bit dev environment than what is mentioned earlier in this thread? Thanks!
