Compiling fails on an M1 Mac about hashlink HOT 7 CLOSED

Did you make sure to install all the dependencies?

Did you make sure to run brew bundle with the x86_64 build of homebrew?

yes

Looks like the path for libpng is missing here? You could try adding it.

Alternatively, you could also try the makefile patches for M1 from this PR: https://github.com/HaxeFoundation/hashlink/pull/577/files#diff-76ed074a9305c04054cdebb9e9aad2d818052b07091de1f20cad0bbac34ffb52

Unfortunately, neither of those ideas worked. I get the same ld: library not found for -lpng error after adding the directory where libpng is.

And when using the branch in the PR I get this when running make:

ok, I finally got it working. Thanks for your help @tobil4sk
I did indeed need to add the libpng library dir to that line that sets LIBFLAGS, along with several others. In the end, this is what worked:

LIBFLAGS += -L/usr/local/homebrew/opt/libjpeg-turbo/lib -L/usr/local/homebrew/opt -L/usr/local/homebrew/opt/jpeg-turbo/lib -L/usr/local/lib -L/usr/local/homebrew/opt/libvorbis/lib -L/usr/local/homebrew/opt/openal-soft/lib -L/usr/local/homebrew/opt/libpng/lib -L/usr/local/homebrew/opt/sdl2/lib -L/usr/local/homebrew/opt/mbedtls@2/lib -L/usr/local/homebrew/opt/libuv/lib

I hope this is useful for anyone else with an arm64 Mac.
