This is a good example of the need for compilers that output the code they generate based on templates. If they did that, the library writer could have an online service that spits out the final deliverable rather than users having to maintain different versions of a library.
I don't understand the advantage over preprocessor configuration. I don't really want to have to have a separate boost distribution every time I want a different configuration.
It is a slow and error prone process to rebuild a library/application as suggested here. Alternatively, service providers would have logging versions of their code available for users in the field, in effect eliminating the long and unproductive process of a rebuild.
How is this any better than just providing pre-built binaries. Unless different configurations are ABI compatible, switching configurations requires a re-build of all user code that depends on the library regardless of how the configuration is managed.
Because the code is built by the service provider rather than less experienced users, configuration confusion is mitigated. As the needs here are pressing, we hope the problems with the status quo will be addressed sooner than later.
