NFD

Task #2169

Updated by Alex Afanasyev over 9 years ago

Create a wiki page for the issue. I'm putting a straw-man text here. 

 OS X 10.8 by default uses libstdc++ from gcc 4.2.1, which does not support C++11 features.    ndn-cxx, NFD, NLSR, etc. are selecting the correct STL library using `-stdlib=libc++`.    However, all dependencies (boost, cryptopp, protoc, log4cxx) needs to be compiled with the same STL library, otherwise code will not compile. 

 I couldn't find an easy way to do it with macrports.    The following steps assume that [homebrew](http://brew.sh/) is used: 

 The following ports are necessary to compile `ndn-cxx`, `NFD`, `NLSR`, `repo-ng`: 

 - `autoconf` 
 - `automake` 
 - `libtool` 
 - `pkg-config` 
 - `readline` 
 - `sqlite` 
 - `boost` (C++) 
 - `cryptopp` (C++) 
 - `log4cxx` (C++) 
 - `protobuf` (C++) 

 All C++ ports ports, except boost, needs to be configured in C++11 model (with --c++11 flag): slightly updated to be compiled with `libc++`.    The following steps will accomplish the goal: 

 - Preliminary steps 

     Update port definitions 

         brew update 
     

     Install non-C++ ports 

         brew install autoconf automake libtool pkg-config readline sqlite 

 - Install `boost` in libc++ mode: 

         brew install boost --c++11 
     

 - Install modified `protobuf` 

         brew edit protobuf 

     after line 66, add 

         ENV.append 'CXXFLAGS', '-stdlib=libc++' if build.cxx11? 

     After that protobuf can be installed as: 

         brew install cryptopp protobuf --c++11 
     

 - Install modified `cryptopp` 

         brew edit cryptopp 

     after line 11, add 

         ENV.append 'CXXFLAGS', '-stdlib=libc++' 

     Install 

         brea install cryptopp 

 - Install modified `log4cxx` 

         brew edit log4cxx --c++11 
     

     after line 26, add 

         ENV.append 'CXXFLAGS', '-stdlib=libc++' 

     Install 

         brew install protobuf --c++11 log4cxx
