Hi Uri,
Yes, here’s the example I did for our VxWorks wrapper for Boost.
We cross-compile on Windows and Linux, so it just make sure the defaults from the host environment aren’t used.
The feature.feature declares a feature called cross-compile with a possible option of vxworks
The feature.compose declares what selecting the option vxworks does.

feature.feature cross-compile
    : vxworks
    : composite propagated optional ;

feature.compose <cross-compile>vxworks
  : <target-os>vxworks
    <threadapi>pthread
    <threading>multi
    <inlining>full
    <optimization>speed
    <binary-format>elf
    <abi>sysv
  ;

Subject: [Boost-build] How do I specify a dependency for a feature?

Hi,
I'd like to specify a dependency for a feature, like below:

feature.compose <MyFeature>yes :
  <define>MY_FEATURE
  <toolset>gcc-6.0.0:<include>$(dir-6.0.0)/include
  <toolset>gcc-10.0.0:<include>$(dir-10.0.0)/include

Is there a way I can do this with Boost::build?

Thanks,
Uri
