If you want to test a binary on a particular architecture, but you don't
have a machine with that architecture(e.g. mips), you can use qemu to simulate
that architecture.
Here's how.
On ubuntu:
apt install qemu-user-static
First you need your binary compiled for that architecture.
To obtain it, see previous post about cross-compilation.
Or, if you use Go, use the GOARCH variable to compile your program for the wanted
architecture.
I'll use here the binaries from the previous post
and assume the native machine is a x86_64one.
Run on mips:
qemu-mips-static example-mips
hello
Run on aarch64:
qemu-aarch64-static example-aarch64
hello
