    Added to files1.

    If you're running Sieve/PigeonHole, be sure to recompile it afterwards, eg:
    ./build update
    ./build dovecot
    ./build pigeonhole

    Here is what I get as an error on FreeBSD 11:

    I did make ./build iconv (successful reinstall) and it did not help.

    I found this thread, same error:

    Perhaps follow up there. I would recommend trying this in the configure/dovecot/configure.dovecot:
    But reply #8 might be a solution as well with
    LDFLAGS="-L/usr/lib/dovecot -L/usr/local/lib"export LDFLAGS=${LDFLAGS}
    added to the configure.dovecot file, before the ./configure call and after the #!/bin/sh line.

    If it works, please also follow up, and we can test it out in more detail.

    Our FreeBSD 11 box isn't duplicating the error, hence I'm hesitant to make the change permanent for all until we know more.
    But as mentioned, as it's the exact same error as t=54461, I would recommend following up there with success so we keep things as unified as possible

    If anyone else is getting the same error for FreeBSD 11, please do chime in so we get a better gauge of all affected.

    did NOT fix the issue. Making...

    # pkg query %ro libiconv >ports_to_update
    # pkg delete -f libiconv
    # cat ports_to_update | xargs portmaster
    did NOT help. Adding...

    LDFLAGS="-L/usr/lib/dovecot -L/usr/local/lib"
    export LDFLAGS=${LDFLAGS}
    to the configuration file FIXED the issue!

    Great, thanks for the feedback.
    I've tested the setting on various different operating systems and versions, and none failed with the setting.
    I'll discuss with Martynas to look into making it present by default.

    I am more curious what triggered the issue. Before 2.3.3 I had no issues compiling dovecot. From the other thread I see that it appeared for other people on older versions.

    My guess is that it could be related to a conflict between libiconv in ports and iconv in custombuild. But recompilling both did not help.

    The configure.dovecot has not been touched for 1530 days, 14 hours.. according to SVN
    So not too sure.. probably some change in the ./configure or code.. no idea.
    Martynas has added this, just for the FreeBSD case:
    if [ "${OS}" = "FreeBSD" ]; then
    export LDFLAGS="-L/usr/lib/dovecot -L/usr/local/lib"
    I did test it on various boxes, so if anyone actually hits that error, let us know and we can move it outside of the "if FreeBSD" condition to make it global.. but for now, it's just there for FreeBSD, before the automake+make (after the ./configure call).

    Let us know if you still have issues with it.
    It's on files1, ./build version rev 1925.
