updating - re ran a 'pkg install -forge nan' on another 6.4.0 install that had not yet been updated from nan 3.6.0. Most of the same shadowing warnings messages appeared, but I also got ./configure and readlink messages I hadn't gotten before:


octave:2> pkg install -forge -global nan
./configure: line 3811: which: command not found
readlink: missing operand
Try 'readlink --help' for more information.

with a fresh install of Octave 7.1.0 on Windows 10 (using 7z package and after running the post-install.bat script), calling

pkg update -global

produces the following set of warnings/errors. The warnings are clearly from the nan package. although not as clear, the first set of messages also appear to be from the nan package, based on there being no intermediate 'for information about changes from previous...' message, but I haven't confirmed this.

For information about changes from previous versions of the nan package, run 'news nan'.


The latter warnings are generally inconsequential, but is it expected to get all such shadow warnings on install versus just on pkg load? I would suggest that a flood of such warnings are not necessarily useful there, perhaps unless -verbose has been requested.

The former warning may be more concerning, but it didn't seem to prevent package install.
