yep. we don't have the crossbuild-essential-mipsel package. While for normal user, it is not useful at all. crossbuild-essential-armhf depends on g++-arm-linux-gnueabihf && gcc-arm-linux-gnueabihf So, you can do the same thing just by apt install g++-mipsel-linux-gnu # gcc-mipsel-linux-gnu is not needed, since g++ depeds on gcc. > > However, similar steps don't work on mips64.
