To make this repo compatible with MSYS2 mingw and other OS (Linux, macOS, BSDs) #1

Open mcuee opened 6 months ago

mcuee commented 6 months ago

One way to fix https://github.com/avrdudes/avrdude/issues/1653 is to use this repo for avrdude, not only for MSVC build, but also for other OS.

It actually build under MSYS2 mingw.

It also works under macOS. Tested under macOS 14.3.1, Mac Mini M1 2020.

But take note currently it only build static link library.

Hey @mcuee, if static libelf is compiled from this, can we use it in place of libelf provided by brew ?

This is supposed to be the case. But please test against your application.

hp77-creator commented 2 months ago

I am trying to compile libbpf on my system(macOS m2), brew and macports aren't working. Stumbled upon an issue that was raised by Homebrew maintainer in your repo. And now I am looking for alternatives.
