Hi.

Having just removed a number of configure options from the cross compilers
recipe to simplify the problem I think one of those I took away overrode
--without-shared-libs. Now it seems to install and run cleanly. Even so,
while building the ipackage I spotted some warnings. Could these because
by my build environment? After some testing I'll let you know if the
current dovecot build works. I really appreciate your support and
patience, thank you.

Hi.

Thanks, I'll give that a try.

I've made a new attempt at build Dovecot. The build and then install processes appeared to work find. Then when I try to run Dovecot it reports the error:

/share/MD0_DATA/optware/opt/sbin/dovecot: error while loading shared libraries: libdovecot.so.0: cannot open shared object file: No such
file or directory

In cases like this where I have no clue where an executable is trying to load a library from, run a process trace tool (strace, truss, etc.) and
you can see all the library run paths it's trying before failing.

Hi.

Dovecot appears to be running (testing required).

This is normal.

Okay.

/opt/sbin/dovecot: error while loading shared libraries:
libdovecot.so.0: cannot open shared object file: No such file or
directory

So it's still not working? I guess the libdovecot.so.0 simply isn't in
library paths. Typically giving linker -rpath parameter pointing to
libdovecot.so.0 makes this problem invisible, but I guess in your system
it doesn't do this.

So far Dovecot seems to be running. I don't want to say it's working or
not until I've done some tests. This is using
--without-shared-libraries. If it's just the linker in my system that's
broken then this is an adequate solution. Otherwise any information I can
produce might be useful to you is desirable.

--enable-devel-checks is pretty useless unless you're developing Dovecot.

This panic is caused by the --enable-devel-check. It wouldn't have
crashed otherwise. You could work around it by setting GDB=1 environment.

I put --enable-devel-check in there in the vain hope that it'd elicit
anything useful. I would suspect that this is again the build
environment. I won't included in any further tests.

Thanks again.

I am planning to use Dovecot SASL with Sendmail as well, will this lack of shared libraries cause a problem? Really I should have thought of this before.

I don't think Sendmail supports Dovecot SASL? If it does, it talks to Dovecot via UNIX socket and doesn't require any Dovecot libraries.
