This warning is for project developers.  Use -Wno-dev to suppress it.

I also suppressed a number of warnings as shown below. They were all of the same variety--the only difference being that each had a different template argument-- so I've only included one of them.

Just Googling around, it seems like reinstalling the Command Line Tools is a common solution for this problem:

https://groups.google.com/forum/#!topic/crystal-lang/tMcFSbvYRlA
brianmario/mysql2#795

Those links recommend xcode-select --install, however I think that will install the latest version which isn't what you want. Try reinstalling 9.2 following the link from the Installation wiki.

Out of curiosity, before you do that what is the output of "clang -v"?

[jmininger]

Thank you for the suggestion.
Here is the compiler info:

clang -v
Apple LLVM version 9.0.0 (clang-900.0.39.2)
Target: x86_64-apple-darwin17.4.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

That version builds Peloton okay for me. It seems like wires are crossed on your system with respect to where to look for the SSL library. Apple rolled their own starting with El Capitan, but you likely have some OpenSSL packages installed via Homebrew as well that might be mixing things up if you symlinked them into other places. All I can suggest at this point is reloading your dyld cache...

sudo update_dyld_shared_cache -force

...and perhaps checking for any weirdness with Homebrew with...

brew doctor

Beyond that it's tough to say why linking in the SSL library is failing on your machine.

[poojanilangekar]

What the version of SSL installed on your machine?
You can figure that out using the openssl version command

[jmininger]

OpenSSL 1.0.2l 25 May 2017

[poojanilangekar]

The version seems fine. I think there is an issue with the path. Find the location of your current OpenSSL installation using which openssl. Now add the path you find without the trailing openssl to the $PATH variable. Let me know if it fixes your issue.

[jmininger]

I was finally able to build it after reinstalling Xcode command line tools (as suggested above), and after uninstalling anaconda and reinstalling python3. I still had to use the
-DCMAKE_CXX_FLAGS="-Wno-error=pointer-bool-conversion" for the build to work though. Thank you for your suggestions
