Building SimplePerf

[coconut water]

Hi all. I am currently trying to build a simpleperf.exe for windows. At this point, I have already fetched the entire Android source code, the source code for simpleperf and got a clang++ on my machine. I have a few questions listed below:

1. Is there anything else that I need?

2. How should I build such a simpleperf.exe? Should I specify the target platform in clang?

3. Finally, does anyone know how to build simpleperf for windows?

Thanks for all reply, if any

just `lunch` any target and then build in system/extras/simpleperf ...
the Linux build automatically cross-compiles the Windows tools using a
prebuilt mingw that's part of the tree. it'll be in
out/host/windows-x86.

Yeah thanks for your help. Is it necessary to compile the entire Android, which I heard to be time consuming, probably taking 6 hours on a standard workstation. Or can I just compile the part depended by simpleperf?

that's why i said "build in system/extras/simpleperf" :-)

This is super helpful, and I have already built what I need.    Thanks!
