MaplePrimes - answers and comments on Question, error, cannot open archive, /home/salvatore/maple11/lib/, for writing

Maple is correct

You are trying to save your package into Maple's global library -- and it refuses to do so, which is as expected. savelib is a rather low-level command. You should look into LibraryTools, and LibraryTools:-Save in particular. Note how you usually have to specify an archive, one which is writeable by you.

Ok, I've created a init text file in /lib directory with the savelibname command, and it work proprely. Tk you! S.

init file

If you put it into the /lib directory, then that is a 'global' init file for everyone on your computer (and all maple sessions). It is more usual to put the init file in your home directory (wherever that is, depending on your platform).

Tk you for the help So I've created a folder inside "lib" and I've added this address with the line: savelibname:= .../lib/newdossier; and this seems to work. A question: I've to add this address any time I open maple, or the program remember it? Tk you S.

use Maple initialization file

You can put the assignment in the Maple initialization file. See ?maple for details. For linux, create a text file ~/.mapleinit with the line

libname := "/home/yourname/maple/lib/newdossier", libname:

More useful might be something like

# ~/.mapleinit - Maple initialization file
# This is read each time Maple is started or restarted.
# Assign global variable mylib and reassign libname and savelibname to use it.

mylib := "/home/yourname/maple/lib/newdossier":  # adjust as appropriate
libname := mylib, libname:
savelibname := mylib:
