Thanks for your patience, I appreciate the effort trying to solve this.
Here is the gdb log:
1561 return XSTRING (string)->u.s.data;
(gdb) n
5321 if (file_access_p (fndata, F_OK))
(gdb) step
file_access_p (
file=file@entry=0x555555cf8838
"/usr/local/libexec/emacs/28.0.50/x86_64-pc-linux-gnu/../../../../bin/../lib/emacs/28.0.50/native-lisp/28.0.50-864bf4e5/preloaded/window-0d1b8b93-dcb2375f.eln",
amode=amode@entry=0) at fileio.c:162
162 if (faccessat (AT_FDCWD, file, amode, AT_EACCESS) == 0)
(gdb) next
dump_do_dump_relocation (dump_base=<optimized out>, reloc=...) at
pdumper.c:5325
5325 eln_fname = make_uninit_string (execdir_len + fn2_len);
(gdb) p (int)errno
$1 = 13
I can indeed access
/usr/local/libexec/emacs/28.0.50/x86_64-pc-linux-gnu/../../../../bin/../lib/emacs/28.0.50/native-lisp/28.0.50-864bf4e5/preloaded/window-0d1b8b93-dcb2375f.eln
but only as root. Which seems wrong. I can start emacs as sudo ( have not
even checked this before )
Which is then probably a umask issue as this folder's permission seems
wrong:
/usr/local/lib $ sudo ls -lah emacs
total 12K
drwx------ 3 root root 4.0K Aug 3 23:00 .
drwxr-xr-x 4 root root 4.0K Aug 3 23:00 ..
drwx------ 3 root root 4.0K Aug 3 23:00 28.0.50
sudo ls -lah emacs/28.0.50
total 12K
drwx------ 3 root root 4.0K Aug 3 23:00 .
drwx------ 3 root root 4.0K Aug 3 23:00 ..
drwx------ 3 root root 4.0K Aug 3 23:00 native-lisp
Yes the file exists, but I cannot access it as a non-root ( should have
checked before ). I can remove the folder and re-install and the permission
is the same as above.
