Instead of "readelf", use "ldd -r" - it will show you the path to the
libgiac used which - given there was no such file in your list - should
turn out to be the system one.

And
readelf -V /usr/lib/python3.13/site-packages/sage/libs/giac//
giac.cpython-313-x86_64-linux-gnu.so
did not show 1.9.0 anything. Also tried
strings /usr/lib/python3.13/site-packages/sage/libs/giac//
giac.cpython-313-x86_64-linux-gnu.so
And same thing, I could not see 1.9.0 anything on the screen.
But it seems the arch sagemath pacman package is using its own builtin
giac, right? Since it is using
giac as shared library in the above .so. Just need to know which version
of giac it is using.
someone from Arch should know this, the person who build the sagemath
pacman package. It has
the name Antonio Rojas <https://archlinux.org/packages/?
maintainer=arojas> there. Will try to ask them and see if they would know.
Thanks.

That is all. I see the file
/usr/lib/python3.13/site-packages/sage/libs/giac/
Is this the giac sagemath 10.5 is using then? If so, how to find
the version of giac it is using?
It would be much better if it is using the system giac, but I am
still not sure
which giac it is using.
Will see if I can find more information.

It is very likely that sagemath installed by pacman from AUR
uses the
system giac. But you can check the list of files installed by
pacman for
sagemath.
pacman -Ql $package_name
if it includes a private copy of giac, it should appear in the
list.
