Problem when I make wangle in OSX about wangle

[anirudhvr]

The SSL warnings are because Apple has "deprecated" OpenSSL for some time. This doesn't mean anything other than you should probably verify which version of OpenSSL is being linked in, and perhaps install your own using homebrew.

The actual error is that the linker can't find -latomic. I don't believe wangle is "officially" supported on OS X, but since this is part of C++11, can you try removing '-latomic' from CMakeLists and try?

Problem is the CMakeLists.txt file has the CXX Compiler Flags set to -std=c++11. Replace that with -std=c++14 and it'll compile fine. You can also check my pull request which fixes the OS X build : #47

After removing -latomic from Cmakelist I got:

any tips?

Update:
I'm compiling without tests, seems to be doing the trick: cmake -DBUILD_TESTS=OFF . && make

@bithavoc, it says "types are a C++14 extension". Does your compiler speak C++14?

it should
