Hi,

Configure error:
- liblockfile package installed and `configure --without-x`

checking for maillock in -lmail... no
checking for maillock in -llockfile... no
checking for liblockfile.so... yes
configure: error: Shared liblockfile found but can't link against it.
This probably means that movemail could lose mail.
There may be a 'development' package to install containing liblockfile.

No configure error:
- liblockfile package not installed
- liblockfile package installed and `configure` (no arguments)
- liblockfile and GNU mailutils packages installed

What do you recommend for the package?

1. We could just add ac_cv_prog_liblockfile=no to the configure environment.
2. We could add a dependency on GNU mailutils.
3. We could add an option to depend on GNU mailutils.  If that option is turned off, then add ac_cv_prog_liblockfile=no to the configure environment.
4. Another approach I am missing.

Thanks,

Joseph

Could you show us the config.log corresponding to this error? And tell
us which version of Emacs you're building?

The fact that this happens only when using '--without-x' indicates to
me that there might be a bug in our configure script which we should
attempt to fix.

This is with version 25.3 and with a recent commit from the master branch.

Here is the config.log (liblockfile installed and --without-x).
https://ftfl.ca/misc/emacs_nox_error_liblockfile.log

Here is the config.log for a successful configure (liblockfile installed)
https://ftfl.ca/misc/emacs_config.log

These are the files included in the liblockfile package.

That sounds like it's the easiest fix. These days GNU mailutils is recommended 
anyway, as Emacs's own movemail program retrieves POP3 email only via insecure 
channels.

Sounds good, I will add that dependency.  However, it looks like I was mistaken.  Also depending on mailutils does not fix the issue with liblockfile installed and supplying the --without-x argument to configure.  Should both mailutils and liblockfile be added as dependencies?

In any case, it still seems like there is a problem with the configure script.  Shouldn't it be finding the installed maillock.h and be able to link against the lockfile shared library?

Thanks,

Joseph

The liblockfile checks pass after adding LDFLAGS+=-L${LOCALBASE}/lib.
Based on bug #10313, this addition to LDFLAGS feels like the right
approach for the FreeBSD port/package.

The confusion about GNU Mailutils fixing the problem was due to the
differences between 25.3 and the master branch.  In the master branch,
the locking tests are wrapped in

if test ! "$with_mailutils"; then
...
fi

Given this, I assume functionality provided by liblockfile is duplicated
in mailutils.  I think a sensible approach for the port/package would be
to set ac_cv_prog_liblockfile=no and, as you suggest, (optionally)
depend on GNU Mailutils for users that require movemail and the other
functionality provided by Mailutils.

Thanks again,

Joseph
