[Scons-users] Identical file names in VariantDir and source dir

[Dmitry Mikhin]

Hi William,

Thanks for the prompt reply.

Yes, I know about the duplicate and use it when necessary, but this
was not the intent in this case. Correct me if I'm wrong, but
"duplicate" applies to the entire VariantDir directory, you cannot
cherry-pick separate files, right?

For now I'm just renaming everything to be safe (and to find out all
the black spots in the process; 14 tests so far, but none major to my
relief). The srcpath is a good suggestion, I'll see if the builder can
use it.

I'll file a ticket. It's a bit harder with the example because I'm
using too many custom builders to arrive at the result. Probably will
write a small test case instead of cutting the large project.

I thought I did! And that was the main problem :)
Cheers,
