[Swift-user] Errors when not explicitly mapping outputs

[Mark Maienschein-Cline]

Hi,
I'm getting an error when I don't map the output filenames of applications explicitly, instead allowing swift to come up with its own names., e.g.

file input<"test">;
file output;
output = program( input );

fails, citing the fact that _concurrent/output-... was not created. If I map output explicitly, it runs fine. Is there an extra setting I need to make sure is turned on for swift to map its own file names?

Thanks,
Mark
