Compiling MultiChain on Mac OS X Mojave

Question

Greetings,

I'm trying to compile the Multichain code on Mojave

Xcode 11

I've tried many Boost versions 1.57 / 1.59 / 1.60

but encounter many warnings and errors ex :

Would you please help me find the correct libraries versions, please ?

 

/usr/local/include/boost/asio/ssl/detail/impl/openssl_init.ipp:43:23: error:
      expected unqualified-id
    mutexes_.resize(::CRYPTO_num_locks());

/usr/local/include/boost/asio/ssl/detail/impl/openssl_init.ipp:46:66: error:
      expected unqualified-id
    ::CRYPTO_set_locking_callback(&do_init::openssl_locking_func);

 

-------------------------

With boost 1.57 the error are :

Answer 1

MultiChain for OS X requires Boost version 1.57. Could you please try compiling it with that, and then post any *errors* you see (don't worry about warnings).

Comments

Thank you. I've started with 1.57 (as mentioned in the Mac.md file)
I've inserted the first couple of errors at the end of the question.
Thank you

Thanks for your reply. So it looks like something broke in the build process on this newer version of Mac OS X. We will look into this when we can – in the meantime perhaps you can find a Mac running an older version?
