bug#55741: Getting an error when running the Emacs 28.1 binary that I built from source

[cinnaroll45 via Bug reports for GNU Emacs, the Swiss army knife of text editors]

[-- Attachment #1: Type: text/plain, Size: 1768 bytes --]

OS: Debian 11 (Fresh Install)

ARCH: amd64

When building Emacs 27.2 from source, I use the following config:

```bash

./autogen.sh
./configure --prefix=/home/user/emacs --bindir=/home/user/bin \
    --with-json --with-gif --with-jpeg --with-png --with-tiff --with-rsvg

```

It builds without an issue and the binaries end up in my PATH and I can run Emacs.

When building Emacs 28.1 on the same system, I use the same config but with the addition of the `--with-native-compilation`flag:

```bash

./autogen.sh
./configure --prefix=/home/user/emacs --bindir=/home/user/bin \
    --with-native-compilation \
    --with-json --with-gif --with-jpeg --with-png --with-tiff --with-rsvg

```

The build goes without a hitch and the binaries end up in my PATH. However when I try to run the Emacs binary, I get the following error:

`Error using execdir /home/user/emacs/libexec/emacs/28.1/x86_64-pc-linux-gnu/../../../../bin/:
emacs: /home/user/emacs/libexec/emacs/28.1/x86_64-pc-linux-gnu/../../../../bin/../native-lisp/28.1-2120ad00/preloaded/window-0d1b8b93-7ef4271a.eln: cannot open shared object file: No such file or directory`

I should also note that, if I try to run the built binary within the `src`folder, Emacs starts without an issue. Only the binary that's on my PATH seems to have this error.

I have found a very similar problem on the emacs-devel mailing list:

[https://lists.gnu.org/archive/html/emacs-devel/2021-05/msg00003.htm](https://lists.gnu.org/archive/html/emacs-devel/2021-05/msg00003.html)

However, the person is trying to create a deb package so the recommendations there didn't help me.

Both source files are tarballs from the GNU FTP server and my system is Debian stable. Cleaning up build configs and trying fresh builds has not helped.

The --bindir switch could be the problem: as you see from the error
message, Emacs 28.1 thinks its binary is in /home/user/emacs/bin, not
in /home/user/bin.  So my suggestion is to reconfigure without the
--bindir switch, as I don't think this is currently supported for the
build with native-compilation.

Can you show the full absolute file name of the file
window-0d1b8b93-7ef4271a.eln with this installation?  In which
directory is it installed by "make install"?

And in addition, please show the full absolute file name of the
emacs.pdmp file, so we could know in which directory it is installed
on your system.

Thanks.

The *.eln files should be under /home/user/emacs/native-lisp/, can you
see if they are indeed there?

Removing the --bindir switch solved the issue for me. Everything gets installed to the
expected location and the Emacs binary runs.

The location of the pdmp file was:
/home/user/emacs/libexec/emacs/28.1/x86_64-pc-linux-gnu/emacs.pdmp

> Can you show the full absolute file name of the file window-0d1b8b93-7ef4271a.eln with

I couldn't expand the absolute location of `window-0d1b8b93-7ef4271a.eln`. The error message seemed to
indicate that it was looking for it under the directory where `emacs.pdmp` is, however there were no
directories present in that path. Just the pdmp file and three other binaries.

Thank you for helping out!

Thanks, but could you please test a possible fix for the original
problem?  I'd like us to keep supporting the --bindir configure-time
option, as we didn't intend dropping its support in Emacs 28.

So could you please re-configure Emacs 28.1 with your original
options, including the separate --bindir, and then rebuild it with the
patch below, install it by "make install", and see if Emacs now starts
up correctly?  If it doesn't start (or doesn't build), please show any
error messages you see.  TIA.

Ping!

Could you please try the fix I posted?  I'd like to install it for
Emacs 28.2.

No further comments, so I installed the fix on the emacs-28 branch,
and I'm closing the bug.
