Same question! Is it now OK to output to a different directory? If so,

It works like a charm now (; I've been using this feature ever since it
was available and reported some bugs, but all of them are fixed now.
Moreover - with lua parser you can have output files in an identical
tree as sources, but this whole tree can be in a subdirectory of the
project! So if you have folders with sources:
a/*.c
a/a1/a2/*.c
b/*.c
c/*.c
d/*.c
d/d1/*.c
tup is able to compile all of the sources into relevant folders of this
hierarchy:
output/a/*.o
output/a/a1/a2/*.o
output/b/*.o
output/c/*.o
output/d/*.o
output/d/d1/*.o
(the name "output" is just an example - it can be anything)
You can check this project of mine, which has tupfiles written in lua
and they do exactly that:
https://github.com/DISTORTEC/distortos
In case of tupfiles written in "original tup parser" it's a bit harder
and I guess such build as above wouldn't be possible (without manually
stating outputs for each subfolder of the sources)... I usually just
output all files into one subfolder, with no hierarchy (all of them go
into this folder), so the only limitation is that I cannot have two
object files with the same name (probably a bad idea anyway to have two
source files with the same name). It would be probably easy to improve
this hierarchy - you could easily output to a subfolder of this "output"
folder, with the subfolder named as the last directory of the sources.
Taking the above example, it would look like that:
output/a/*.o
output/a2/*.o
output/b/*.o
output/c/*.o
output/d/*.o
output/d1/*.o
Ask me anything about that, as I've excercised this ability of tup a lot (;
