Build instructions mention using newer/maintained variants at https://github.com/avrdudes/avrdude/wiki/Building-AVRDUDE-for-macOS and https://github.com/avrdudes/avrdude/wiki/General-Build-Instructions though may need to check if feature-complete.

• libusb vs libusb-compat
• hidapi vs libhid
• libftdi vs libftdi0

BSD is GPL-compatible, so elftoolchain should be fine.

[cho-m]

I think this only uses libelf.a (no dynamic lib in formula). Could also consider disabling ELF feature since not sure how to handle unmaintained libelf. Was previously looking at elftoolchain but not ideal to mix BSD license while elfutils doesn't build on macOS. Upstream does have its own repo copy of libelf but mainly for Windows build.

[cho-m]

Note that this only builds static lib. Was trying -DBUILD_SHARED_LIBS=ON but hit some undefined symbols and haven't had time to debug it. Though, only using cmake on HEAD since this is what upstream recommends while tarball only has autoconf files. So, may not be too important about libs.

[carlocab]

Try -undefined dynamic_lookup for undefined symbols.

@cho-m You need to add back libusb-compat, if not many programmers will not be supported, so far only usbasp supports libusb-1.0.
