[Scons-users] Handling deleted source files

[Tom Tanner (BLOOMBERG/ LONDON)]

shouldn't that be Depends(generatedFiles, cppSourceFiles)? Currently you state all your source files depend on the generate files, which seems wrong.

Ah thanks - I tried running with --debug=explain --tree=all and there seems
to be some dependency between some other generated files and the removed
.cpp, even though I thought these should go the other way round as I have
Depends(cppSourceFiles, generatedFiles)

I will have to strip this down to a simple example to get to the bottom of
it...
