Windows Installer: The R choice is not unselectable
Added by Christopher Brooks almost 13 years ago.
Updated almost 13 years ago.
Description
When installing under Windows, I'm given a choice of which components
to install: Kepler and the R interface.
However, the R interface checkbox is not selectable, so I have to install
it.
Why do we offer the user the illusion of choice if they can't make
a choice?
This is minor and in no way a blocker, so feel free to retarget.
This has been bugging me as well, it's confusing and pointless. If I have time I'll try to look into it.
I'm not sure why we offer the choice at all. We decided a while ago that we shouldn't ship R with the installer because R is GPL'ed and that causes conflicts. So... we probably should remove the choice altogether.
This shouldn't be hard to fix at all. You just need to modify the files that control IzPack. I would suggest fixing this before releasing 2.3.
The "R Kepler Module" checkbox appears to only install the R interface, not
all of R. The size is reported as 1.86Mb.
The description is:
"Installs the R module which allows Kepler to use the R analytical engine."
It is an interesting question about whether shipping the R interface
means that Kepler is GPL'd. If I remember correctly, if the
"R Kepler Module" calls R by executing it as a subprocess, then Kepler
would not fall under GPL. If the "R Kepler Module" calls R via
shared libraries (or the Java classpath?) then Kepler would fall
under GPL.
Someone should check for sure.
I do agree that Kepler should definitely not ship the R installer.
Should be fixed at r28913-14:
fix http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5507 -- no longer show unchangeable 'R Kepler Module' box during install. The R module gets installed regardless, I don't know why this was reworded instead of removed when we stopped including R itself as an optional install.
I tested an R workflow in windows after installing with a test installer where the checkbox is removed, and it worked. I can also instantiate an R actor from the R folder in the components lib.
If anyone see a problem with anything R related, especially on Windows, reopen.
Original Bugzilla ID was 5507
