[Radiance-general] GenCumulativeSky compiled for Mac?

[Thomas Bleicher]

Ji

The messages you are seeing are not errors, just warnings. Errors stop the
compiler from creating the binary. In your case the binary is successfully
created.

The warnings seem harmless to me in the given context. So I suppose it's
save to ignore them.

Regards,
Thomas
