I've no idea about writing a port, but here's my notes on compiling ethereum using macports. Just compiled, not extensively tested. This macbook's running OSX 10.11.6 :- $ uname -a Darwin tango.lan 15.6.0 Darwin Kernel Version 15.6.0: Mon Nov 13 21:58:35 PST 2017; root:xnu-3248.72.11~1/RELEASE_X86_64 x86_64 i386 MacBook7,1 Darwin $ port version Version: 2.4.2 $ cmake --version cmake version 3.10.1 $ which clang++ /opt/local/bin/clang++ $clang++ --version clang version 5.0.1 (tags/RELEASE_501/final) Target: x86_64-apple-darwin15.6.0 Thread model: posix InstalledDir: /opt/local/libexec/llvm-5.0/bin So try number one :- git clone --recursive https://github.com/ethereum/cpp-ethereum.git cd cpp-ethereum/ mkdir build cd build CXX=/opt/local/bin/clang++ cmake .. make This failed with an error in deps/src/libff/libff/common/profiling.cpp complaining about this line :"::clock_gettime(CLOCK_PROCESS_CPUTIME_ID, &ts)" Some flailing around on google and it seems that this function only exists in OSX 10.12 but there are work-arounds, e.g. https://stackoverflow.com/questions/5167269/clock-gettime-alternative-in-mac-os-x So, very smelly hack: use the work-around already there in header oce/gettime_osx.h from macport oce; i.e. add #include <oce/gettime_osx.h> to deps/src/libff/libff/common/profiling.cpp Now compiles to completion. $ ./eth/eth --version eth version 1.3.0 eth network protocol version: 63 Client database version: 12041 Build: Darwin/clang/Interpreter/RelWithDebInfo $ otool -L ./eth/eth ./eth/eth: /opt/local/lib/libleveldb.1.dylib (compatibility version 0.0.0, current version 0.0.0) /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 120.1.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1226.10.1) The build uses a compile-time dependency system "hunter" https://docs.hunter.sh/en/latest/ and that sucks in quite a lot of stuff to ~/.hunter including a new copy of boost. $ ls ~/.hunter/_Base/Download/ Boost/ Hunter/ Snappy/ cryptopp/ jsoncpp/ libjson-rpc-cpp/ yaml-cpp/ Don't know how that will interact with a macport. NB oce and leveldb ports needed. -- Red to red, black to black, switch it on, but stand well back.
