Octave install warning about verLessThan.m

[justinkelly-ie]

Hi, I'm Getting the following warning when installing in Octave:

warning: Permanently renaming verLessThan.m since it is already present

[dlegland]

Hi,

this is strange, as the file belongs to Matlab, but is not included into MatGeom...

maybe the problem comes from octave updates to match the function. Have you encoutered it with other libs?

Hi, thanks for the reply.

I could install the general package.

I get a similar message attempting to install matgeom, full message:

I just updated to Octave 7 and now getting this error (on Fedora Silverblue):

wow...

not sure I can help a lot, but few things:

• last version of the library is 1.2.5, it seems you got an older one
• I'm really lost in the error messages you got...
• where did you get the library from? I know there was a port to octave, but I do not maintain the octave version (just try to keep the Matlab version as much compatible with octave as possible...). I suggest asking to the maintainer of the octave port.

Hope this helps...

Ah, cool, thanks. I got if from Octave forge https://octave.sourceforge.io/packages.php
Maybe updates have stalled, thanks for taking a look.
