If you try to compile it with such a command

bjam --toolset=gcc "--prefix=c:\mingw\include\boost\install" install

I have already tried the tools, and that is not only this, but the result is always the same.

  • Versions of bjam and Boost.Build core do not correspond to each other (though a warning, but if it doesn’t work, then it’s better nafig). Is everything OK with previous (or stable) versions? And the fact that there is no compiler in the visible surroundings - is this normal (default command 'g ++' not found)? - alexlz

Here is the main error: no command provided, default command 'g++' not found .

Try running g++ from MSYS / cmd , if it doesn't work, then you need to install it (for example, via mingw-get ).
