[PATCH 0/3] Waf: Semi-automatic generation of results for cross-answers files

[Stefan (metze) Metzmacher]

Hi Uri,

> Well, it seems the approach I took with this patch is not the correct one,
> because some tests depend on
> results of previous tests.
> This dependency comes in two flavors:
> 1. Test B runs only if test A failed - it's in the logic of the test script
> (e.g. test for "-D_FILE_OFFSET_BITS=64" only runs if test for native large
> file support fails)
> 2. A more subtle one - test A success sets a compilation flag (e.g. large
> file file support), which alters the compilation of test B (e.g. fcntl
> locking)
> 
> The approach of the patch was to run configure to completion and then run
> all tests on the target - given the above it cannot work.
> 
> The only rigorous approach is either to stop configuration when an unknown
> value is detected, or to automatically run the test on the target (e.g. via
> a script supplied to configure) and continue.

That sounds like the --cross-execute= option...
or do you have something different in mind?
