OK. I have updated the debian patches for this release. Mostly<br>
straightforward, and I see the build has been made a little less<br>
baroque in various places, which is good :-)<br>
<br>
makeinstall.tcl changing its behaviour to use $DESTDIR and make it's<br>
directories was a little surprise, but easily sorted and a cleaner<br>
rules file.<br>
<br>
I see there is now vtk9 support (since 5.5.2). Debian has vtk9 now<br>
(in unstable and testing). Do we get useful things for building<br>
against vtk9 rather than vtk7?<br>
We'd need to use vtk7 (or vtk6) in backports but as vtk is just for<br>
the loch gui and image processing I can't see why different versions would matter.<br>
<br>
Both vtk7 and vtk9 seem to work. I guess we should move on so I'll<br>
move to vtk9 unless someone can think of a good reason why not.<br>
<br>
One oddness:<br>
samples/samples.tcl has had the catch stanza commented out in proc process_files {}<br>
#catch {<br>
eval "exec $p >&@ stdout"<br>
# eval exec "cmd /c $p"<br>
#}<br>
<br>
What's that about? It looks like debugging that accidentally got into<br>
the release? The effect is to prevent the samples build from<br>
completing unless cavern is actually installed. I could make cavern a<br>
build-dependency, but we never have before, and if I just put it back<br>
then the samples build as usual (so that's what I've done for now).<br>
<br>
<br>
