I have a question how building Boost should behave when the user provides wrong configuration information. E.g., suppose you have this in user-config.jam:
using python : 3.20 : /nowhere ;
or alternatively, in 1.42 a user runs Boost.Build as follows:
./bjam -sZLIB_INCLUDES=/still-nowhere ...
What should happen?
- A hard error. After all, the user wanted that specific configuration. And warnings are easy to miss. - A warning. Autodetection will still run and possibly find a random version - A hard error, but also run autodetection and let user know what was found. For example:
Could not find Python version 3.20 in /nowhere. There is a valid installation of 2.5 in /usr. Remove the 'using python' statement to use it.
- A hard error, but also run autodetection and let user know what was found. Could not find Python version 3.20 in /somewhere. There is a valid installation of 2.5 in /usr. Remove the 'using python' version to use Python version 2.5 in /usr or install Python version 3.20 at /somewhere. for the oligoneuronic? (mea culpa!) (Remove the 'using python' statement means you don't want Python at all?) Paul --- Paul A. Bristow Prizet Farmhouse Kendal, UK LA8 8AB +44 1539 561830, mobile +44 7714330204 pbristow@hetp.u-net.com
