here are the different build options and the corresponding results:
Works correctly out of the box and builds to 'darwin-4.2.1â.
$ ./b2 toolset=gcc
Fails to build with everything failing due to '/bin/sh: line 1: -ftemplate-depth-128: command not foundâ. There is probably no value in this working since âgcc' is just a symlink to âclangâ anyway, I just want to mention it for completeness.
$ ./b2 toolset=gcc-4.9
Correctly pickups the compiler but fails to build with
- clang: error: unsupported option 'â64'
- ld: unknown option: -h
The âclangâ errors result from the assembler files of Boost.Context. The linker errors result from the build system expecting the gcc linker instead of the darwin linker.
$ ./b2 toolset=gcc-5
Correctly pickups the compiler but fails for the same reasons as gcc-4.9.
The âhackâ or workaround for this is to define '#using darwin : 5.3.0 : g++-5 : <linker-type>darwin ;â in user-config.jam and build with ' ./b2 toolset=darwin-5.3.0â. This is not a big deal itâs just not obvious.
