ignoring file bcrypt/libstatbcrypt.a when homebrew/binutils was installed

[randy3k]

I am on a macOS. I got the following error when trying to install openssl 1.3 from source.

With some digging, it seems to be related to the command ar which I installed via homebrew/binutils. The installation process works fine once I unlink the binutils. I am not sure if there is any fix for homebrew/binutils. I just want to post the issue here in case someone will encounter the same issue.

I think this is the reason that homebrew binutils is keg_only and hence won't be linked by default: https://github.com/Homebrew/homebrew-core/blob/master/Formula/binutils.rb#L14-L15

How did you accomplish this anyway? Homebrew won't let me do this:

# brew link --force binutils
Warning: Refusing to link macOS-provided software: binutils
If you need to have binutils first in your PATH run:
  echo 'export PATH="/usr/local/opt/binutils/bin:$PATH"' >> ~/.bash_profile

For compilers to find binutils you may need to set:
  export LDFLAGS="-L/usr/local/opt/binutils/lib"
  export CPPFLAGS="-I/usr/local/opt/binutils/include"

Though I am surprised that the newer version of AR generates binaries that are apparently incompatible with the default linker from xcode.

I installed binutils a long time ago and I was able to force link it at that time. I just tried again force linking it and it gave the same error message as yours.

OK so I think this should no longer be an issue with current homebrew. But thanks for raising this.
