Thanks, but I wonder how come no one else is experiencing this
problem on Posix platforms.  Tree-sitter is supported since Emacs 29,
and Tree-sitter was always a "zerover" project.  And yet no one
complained.

So maybe this is an installation issue on your system after all,
regardless of what the Tree-sitter developers say in that issue?

Yuan, any comments or suggestions?

Which is a perfectly fine solution, IMO.

Hello,

according to https://github.com/tree-sitter/tree-sitter/issues/5783 tree-si=
tter is a =E2=80=9Czerover=E2=80=9D project.  The hyperlink says =E2=80=9CE=
macs must explicitly link to an exact (minor) version (ideally statically; =
This Is The Way).=E2=80=9D

Compiling from source and installing it, creates /usr/local/lib/libtree-sit=
ter.so.0.26, I delete the static .a file .  There are no /usr/local/lib/lib=
tree-sitter.so.0 and no /usr/local/lib/libtree-sitter.so .

With that setup, I build emacs 31.1, and linking temacs fails:

gcc -o temacs.tmp \                                                        =

./configure prints: checking for tree-sitter >=3D 0.20.2... yes

Eventually I install the static libtree-sitter.a, and then the linking of t=
emacs completes.

Kind regards // Dilyan
