Bug when compiling with gcc 15

[Dima Pasechnik]

Hi,
Thanks for the message. 
You really don't need to build any sage's spkg's from source on Arch.
(in particular such packages like gmp, which are basically dead wood in
the sagemath tree)

Actually, Arch provides an up to date sagemath package to install, so,
unless you want to hack on Sage source, you most probably just can use.


You can install all the Arch packages you need by looking at the bottom
part of the output of the main ./configure.
Or you can get the list by
running in terminal the following 3 commands.

cat build/pkgs/[a-z]/distros/arch.txt
cat build/pkgs/_pre*/distros/arch.txt
cat build/pkgs/_boo*/distros/arch.txt

HTH
Dima
