MacOS 10.13 Beta Compile Error (BoringSSL), Phoenix Project

Questions / Help
5

So, I’ve been trying a few different things without success.

  • I’ve been playing around with kerl to build and install a custom version of Erlang.
  • I tried to build with different crypto backends openssl, libressl, boringssl in the build options:
--with-ssl=/usr/local/opt/libressl
  • Make sure that libcrypto has been linked correctly:
$ otool -L kerl/19.3/lib/crypto-3.7.3/priv/lib/crypto.so 
kerl/19.3/lib/crypto-3.7.3/priv/lib/crypto.so:
	/usr/local/opt/libressl/lib/libcrypto.41.dylib (compatibility version 42.0.0, current version 42.1.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.0.0)

1> crypto:info_lib().

  • Analyse erl with dtrace and other tools to try to figure out where the crash happens with a simple ssl:connect/3 call:
...

55688/0x1c540c:  open("/Users/redrabbit/kerl/19.3/lib/crypto-3.7.3/priv/lib/crypto.so\0", 0x0, 0x0)      = 33 0
...
55688/0x1c540c:  stat64("/usr/local/opt/libressl/lib/libcrypto.41.dylib\0", 0xB12B0DE0, 0x1)         = 0 0
55688/0x1c540c:  open("/usr/local/opt/libressl/lib/libcrypto.41.dylib\0", 0x0, 0x0)      = 33 0
...
55688/0x1c5400:  open("/Users/redrabbit/kerl/19.3/lib/ssl-8.1.1/ebin/ssl_cipher.beam\0", 0x0, 0x1B6)         = 33 0
...
55688/0x1c53fe:  open("/Users/redrabbit/kerl/19.3/lib/ssl-8.1.1/ebin/tls_v1.beam\0", 0x0, 0x1B6)         = 33 0
...
55688/0x1c53fe:  open("/Users/redrabbit/kerl/19.3/lib/ssl-8.1.1/ebin/tls_socket.beam\0", 0x0, 0x1B6)         = 33 0

From my analyse, I cannot tell where the process is actually crashing. It seems it’s in ssl_connection.beam. But can’t say for sure.

The only external libraries being present in the logs being Erlang’s crypto.so and crypto_callback.so and the ssl lib (in my current test case, libcrypto.41.dylib from libressl).

If anybody more experienced wants to help :innocent:, he/she would be really welcome.

But hey, that’s what happens when you play with the first beta :blush:.
