I also didn't manage to compile master on osx yet.<br>

Some more information can be found here also:<br>

I think most of the dependencies should meanwhile be available on<br>
homebrew (but not sure).<br>
<br>

>> Now as I actually started by installing Qt 5 by mistake, I had the opportunity to see that it leads to a lot of problems to compile the dependencies. As far as I understand, Qt 5 requires C++11, which means one must use the new libc++ library instead of the old libstdc++ (at least on my configuration, with El Capitan and clang/llvm). Some modifications are such that mixing both is not possible, so everything must be compiled from start with C++11 and libc++. Unfortunately most of the dependencies I mention above do not compile without tweaking, and I stopped doing it when it started meaning not only modifying the Makefiles but the code itself...<br>
