Yes. Thanks for the suggestion, I have implemented this using config-cache.jam as an example on how to create the batch setup files. I have it working except for the following issues:
- I would like the setup batch files to be rooted in the build directory for the jamroot regardless of where the command is executed. The example in build-system.jam (line 689) on how to do this looks 'scary' per the comment and in the msvc.init I would presume these things are not even available yet. Any suggestion on how to get this directory?
- I am also writing the batch file creation action to a log file and was hoping that the actions performed (one batch file per cpu) would all be logged to the file specified in the UPDATE_NOW rule but apparently this rule overwrites rather than appending. The only way around this that I can think of is to generate all the cpu specific batch files in one action (if I can figure out how to do this) and have a log file per compiler version. Is this the only option?
