Installation fails, unable to find OpenSSL library

Trying brew install ngx_openresty and get:

This is on OS-X, and OpenSSL appears to be installed:

$ openssl version
OpenSSL 0.9.8zg 14 July 2015

brew list shows openssl in the results as well.

A different mac in our group did not encounter this problem and installed openresty just fine, so it is unclear what dependency might be missing.

[rlamorea]

I think I found the culprit here. We're seeing that those members of our group that updated to El Capitan encounter this problem. It seems like the default openssl (i.e. /usr/bin/openssl) does not have the development libraries.

The workaround is to brew install openssl and then brew link --force openssl. This switches openssl to /usr/local/bin/openssl and the openresty install works fine.

[rlamorea]

Better error handling on this would be nice, though.

ngx_openresty then should depend on openssl (keg only) on el capitan

The workaround described by @rlamorea doesn't work for me:

$ brew link --force openssl
Warning: Refusing to link: openssl
Linking keg-only openssl means you may end up linking against the insecure,
deprecated system OpenSSL while using the headers from Homebrew's openssl.
Instead, pass the full include/library paths to your compiler e.g.:
  -I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

I seem to still have the system OpenSSL installed?

$ openssl version
OpenSSL 0.9.8zh 14 Jan 2016

Any ideas?

[mikz]

I moved to https://github.com/Homebrew/homebrew-nginx/blob/master/Formula/openresty.rb which is copy of this formula.
It has openssl dependency.

[timotgl]

thanks @mikz this finally worked for me!

FYI this worked for me http://stackoverflow.com/questions/32960032/nginx-cannot-find-openssl-development-headers

same issue on mac mac os sierra. The brew force linking is also not working.

use the official repo can resolve it: brew install homebrew/nginx/openresty this one is out dated.

[killercup]

Oh, there's an official formula now? Is there a way to mark this tap/formula as deprecated?
