Build from source with MinGW on Windows

[RusBaratov@…]

Hello, I've trying to build boost with mingw, and I've got error, when --layout=system option is used.

check out (with cygwin):

> svn co http://svn.boost.org/svn/boost/trunk boost-trunk
> svnversion
80897

build (windows cmd.exe):

> g++ --version
g++ (Built by MinGW-builds projects) 4.7.1
> cd boost-trunk
> .\bootstrap gcc

build with --layout=tagged works fine:

> .\b2 --toolset=gcc --layout=tagged

but build with --layout=system failed:

> .\b2 --toolset=gcc --layout=system
...

Atomic will be released on 1.53. Moved to Atomic In case this is an Atomic specific issue.

seems to be a boost.build issue according to: ​http://permalink.gmane.org/gmane.comp.lib.boost.devel/237614

Vincente, a component of "build" means the ticket is for Boost.Build itself. This is not a problem in Boost.Build. The problem is that Jamroot creates a build request that cannot be satisfied.
