I have come to rebuild my boost libraries from an up-to-date develop branch but find a similar issue. I:\modular-boost>.\b2 --version Boost.Build 2014.03-svn .\bootstrap.bat .\b2 headers .\b2 error: Name clash for '<pstage\lib>libboost_system-vc120-mt-1_58.lib' error: error: Tried to build the target twice, with property sets having error: these incompatible properties: error: error: - <architecture>x86 << others messages issued. What am I doing wrong? Thanks. Paul --- Paul A. Bristow Prizet Farmhouse Kendal UK LA8 8AB +44 (0) 1539 561830 I:\modular-boost>.\b2 Building the Boost C++ Libraries.

This fails:
b2 --with-system --with-test
but this works:
b2 --with-test
That last one builds system, chrono, timer, and test. All with asynch-exceptions-on.
I'm at a loss.
My non-expert explanation is as follows:
--with-test builds 'test' and its dependencies (including 'system') with <asynch-exceptions>on.
--with-system builds 'system' with <asynch-exceptions>off.
--with-system --with-test sees that it would need to build 'system' twice, and since 'system' needs to be copied to stage/lib, it doesn't know which one to copy, as the two have the same name.
