The problem is new CFLAGS in the default makepkg.conf, see this forum post.
To fix it you need to install the devtools
package and use the makepkg.conf in /usr/share/devtools/makepkg-x86_64.conf
.
thx @JoanKX
In manjaro, line 22 maybe need change into
sudo pacman -U *.pkg.tar.zst
Arch Linux's libc symbols are available through debuginfod
now.
To enable it in gdb
add set debuginfod enabled on
to your .gdbinit
file. Now the heap
and vis
commands should work out of the box, without needing to recompile the debug symbols for each update of the GLIBC.

are you sure ? just test it out heap
and vis
command from pwndbg it's not working, i even update the pwndbg repo but still need libc debug symbols, here is the proof image https://ibb.co/PzVd54L
Have you installed debuginfod
? A reboot or re-login cycle may be required in order to make it work.
Yes you have to log out and in again for the environment variables to get updated. Thanks for the tip, I didn't even know debuginfod existed
aha, i met the same problem, did you slove this ?
