Nginx OS X Troubleshooting

Nginx Installation Woes on Mountain Lion

I needed to run the beta version of Passenger (3.9.1.beta) to see how New Relic’s Ruby agent fares against it, but hit a problem when installing Nginx for the first time.

Installing via passenger-install-nginx-module was resulting in this error:

Undefined symbols for architecture x86_64:
  "_pcre_free_study", referenced from:
      _ngx_pcre_free_studies in ngx_regex.o
ld: symbol(s) not found for architecture x86_64

Luckily, I found a solution via at The problem was an incompatible version of PCRE that ships with OS X. Once I removed the libpcre* files from /usr/lib, everything worked like a charm.

I’m finding that the *nix’y files that ship with OS X are often the root of a lot of issues if you’re trying to use newer versions of other software that depends on it. At least I didn’t have to double-click an MSI to get it done…
