 |

media-libs/raspberrypi-userland cannot be compiled on arm64 becuase it supports only arm 32bit.
How can I compile it as arm 32bit executables and run it on arm64? |

crocket,
Tell us the problem you want to solve.
Whatever it is, 32 bit media-libs/raspberrypi-userland on a 64 bit PI is not the solution.

I want to measure GPU/CPU temperature on raspberry pi. raspberrypi-userland contains something like vcgenmd which is used to measure temperature. |

crocket,
See this nixcraft page
/opt/vc/bin/vcgencmd measure_temp is a script and should work in 64 bit mode but as you say, it mostly won't build on 64 bit.
That is listed first in the link but keep reading.
You need kernel support.
