Hi,
Still attempting to setup Boost.Build for Hana, I find myself unable to specify the compiler to be used by `b2` on the command line. The system compiler is then used by default, which does not work because I need to test on recent compilers. [snip] You can use the --toolset option:
bjam --toolset=gcc ... bjam --toolset=gcc-4.7 ... bjam --toolset=clang ...
Bjam will look for different versions of compilers installed on the system and invoke the proper compiler based on the toolset name. You only have to have lines like these in your user-config.jam:
using gcc ; using clang ;
In case clang is not in normal places, this part of a user-config.jam would work:
using clang : 3.7 : "/home/evansl/dwnlds/llvm/3.7/prebuilt/clang+llvm-3.7.0-x86_64- linux-gnu-ubuntu-14.04/bin/clang++" : <cxxflags>-std=c++1y ;
an the toolset option would be:
b2 --toolset=clang-3.7
OOPS. For some strange reason, another <cxxflags> and also a similar <linkflags> is needed to get the right stdlib in the link: using clang : 3.7 : "/home/evansl/dwnlds/llvm/3.7/prebuilt/clang+llvm-3.7.0-x86_64-linux-gnu-ubuntu-14.04/bin/clang++" : <cxxflags>-std=c++14 <cxxflags>-stdlib=libc++ <linkflags>-stdlib=libc++ ;
