[zeromq-dev] Building on OS-X

[Robin Scher]

I am trying to do a full build of lib from source on OS-X. I have to build a custom version and can’t just use Homebrew. I did this just fine for many years on Intel hardware through OS-X 10. I am trying to get it to work on M1 with OS-X 13.2, but the same build steps fail. 

1. Fresh git clone
2. Run ./autogen.sh, which succeeds
3. Run ./configure which fails immediately with these error messages:

./configure: line 1: syntax error near unexpected token `('
./configure: line 1: `m4trace:aclocal.m4:15: -1- m4_include([acinclude.m4])’

Does anyone know what the trick is here? Thanks for any input.
