Need to specify --with-opt-dir on OSX 10.11 El Capitan.

[idyll]

Haven't had a change to dig into exactly what's going on but gem install fails on OSX 10.11 because it can't find some openssl headers.

When compiling mini_ssl.c I get a fatal error: 'openssl/bio.h' file not found.

As an aside the openssl situation is getting pretty crazy. Brew installs 1.0.2. Apple still installs 0.9.8. Of course Ruby is using 1.0.1.

If this is still an issue when 10.11 gets to beta 3 I will see if I can suggest a fix.

10.11 removes /usr/include/openssl for good.

[ryanbrink]

Is there a simple workaround I can use for now?

Figured it out. It's not in the 10.11 SDK but is in the 10.10 SDK. Appending the --with-opt-include option seems to work. For example:

gem install puma -v '2.8.2' -- --with-opt-include="/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/"

Hrm, fun. I can make SSL support optional though I wonder if that will confuse folks.

If you are installing home-brew openssl it's a lot easier:

`gem install puma -- --with-opt-include=/usr/local/opt/openssl/include``

@evanphx is there any way to specify a default opt-include path? Seems like you could state that openssl via homebrew is a requirement for installing it on OS X or the user must manually manage it.

On El Capitan, @robertjpayne's answer works.

On El Capitan, @robertjpayne's answer works. many gem could install success in this way

[betoharres]

@robertjpayne worked to me as well ^^ thanks!

[jeremy]

To make this sticky for all your Gemfiles:

bundle config build.puma --with-opt-dir=/usr/local/opt/openssl

Confirm:

$ grep PUMA ~/.bundle/config 
BUNDLE_BUILD__PUMA: "--with-opt-dir=/usr/local/opt/openssl"

I tried this on my mac - 10.15.5 catalina. But, it still shows same error.
Can anyone help me?

@whitehorse0324 it looks like you are running into issue #2304 (it is not solved for Puma 4.x series)
