boost 1.87 does not have bjam options 'numa' or 'context-impl'

[bgemmill]

When compiling boost with fiber, version 1.86 would take the bjam options numa=on and context-impl=ucontext and build appropriately.

With boost 1.87, I see:
error: Invalid property '<numa>on': unknown feature 'numa'.
and
error: unknown feature "<context-impl>"

The documentation still mentions that this is the way to pass these options in; has the method changed?

@olk could you kindly take a look at this? Is the numa=on b2 option no longer supported? This failure is preventing 1.87 from being added to conan-center-index, conan-io/conan-center-index#26185

[bgemmill]

@praetorian20 the removal of those two b2 options led me to have a look at the boost cmake module where libboost_fiber_numa appears to be built by default, and ucontext can be controlled at cmake configure time with -DBOOST_CONTEXT_IMPLEMENTATION=

[praetorian20]

@bgemmill since CMake is not the official build system, I don't know whether we can rely on that or not. I compared boost cmake between the 1.86 and 1.87 tags, there's no modification of fiber build conditions.

Similar comparison of fiber shows Jamfile refactoring, maybe this was unintentionally introduced? I don't understand Jamfile syntax so I can't tell which change is causing this.

should be fixed with commit 238487b fix property numa

[bgemmill]

@olk Can you please also fix the context-impl option while you're in there?

[olk]

b2 context-impl=ucontext works for me - please not that you have to build boost.context too

[bgemmill]

Thanks for checking, if it works for you my b2 instance was probably choking on not recognizing numa and the context-impl error was noise.

I'm building with cmake at the moment, I'll check b2 again when the next boost lands with your fix.
