The clear interface at present is that you need to have a Jamfile. Building using something else as part of the global build is not supported, unless you somehow invoke this something else from your Jamfile. But this would imply that whatever something else you pick - for instance, SCons - would now become a prerequisite for building Boost.
In other words, what does that Jamroot file need to contain at a minimum, to satisfy the global build processes (i.e., the ones used to build Boost as a whole, including building release docs etc.) ?
The global build process currently in use requires you to not have a Jamroot.
There are globally called rules such as "boost-install", "boostrelease", etc. that seem to be required.
Yes, if you want to use the boost-install rule, it won't work without the global Boost Jamroot.
I'm not entirely clear on what we're talking about here though. Are we in the "git clone boostorg/python" standalone case yet, or are we in "git clone --recursive boostorg/boost", except you want to use SCons for libs/python instead?
*Sigh*. Am I expressing myself really that poorly ? I want more autonomy / independence for individual libraries. I want to be able to build them stand-alone, which you tell me already works if I have toplevel Jamroot in my repo, except you then tell me that I may in fact not because the global build process requires me not to have that. I also want to be able to pick my own build (etc.) tools, not in addition to Boost.Build, but instead of it. I understand that right now that's not supported, which is why I'm writing this proposal. What would it take for Boost to support individual libraries to be built with anything else ? What requirements would that "anything" have to meet, and how would it interact with the existing infrastructure to work ? Is that such a strange request ?
