Fixing m4 on MAC OS 10.14.5

Question

I'm having an issue with pecl which is erring out saying phpize had failed.

The problem ultimately seems to be with m4. Error is autom4te: need GNU m4 1.4 or later: /Applications/MAMP/Library/bin/m4

When I run "which m4" I get /Applications/MAMP/Library/bin/m4

However, any command I try to run with m4 like "m4 --version" I get the following:

Abort trap: 6

I can't find a good explanation of that error, but I'm guessing something is corrupted with m4, but I can't figure out how to fix this on a Mac. Do I just download a newer version and run configure, make and make install? Just a little nervous since I have somewhat limit Mac experience.

Answer 1

I've fixed similar issue by executing brew reinstall m4.

Answer 2

In addition to a "brew (re)install m4", I had to temporarily remove "/Applications/MAMP/Library/bin" from my PATH. After that this worked for me.
