more time that I am can afford. I do not understand some of the instructions. One of the bullets says:

"cd into libs/config/test/all and run bjam *MACRONAME compiler-list*, where

...

*MACRONAME* is the name of the new macro, and *compiler-list* is a space

separated list of compilers to test with."

This "compiler-list", I obviously want the macro to work for all

Thanks for pointing me to these instructions. However, it may require of me possible

...

compilers supported by Boost (and perhaps more), but locally, I can only test it on one. In order to define macro correctly, I would have to use Boost's testing facility, but they are only run on develop and master branches which I cannot commit to. Without having tested my macros on all compilers, I am not sure if my pull request would be a decent one. IOW, I have a chicken and egg problem here, which I do not know how to solve.

any help would be much appreciated.

If you can provide the test case I will test locally before committing anyway.

Thanks for the reply. What is expected of me then? Only the test case in the ipp file? Or also bjam generated test files? Or also the macro definitions in the headers, and the docs?

The more you do the less the library maintainer has to do, and that speeds processing the pull request. Most of the above is pretty trivial. For example, to update the docs, edit libs/config/doc/macro_reference.qbk with your favorite text editor. Following the lines that read: [[`BOOST_NO_CXX11_RVALUE_REFERENCES`][The compiler does not support r-value references. ]] Add something like: [[`BOOST_NO_CXX11_RVALUE_REF_THIS`][The compiler does not support r-value references for *this . ]] One thing that can be a bit tricky is editing the compiler files. You might want to just do the one you are testing, and leave the others to config maintainers. --Beman
