Hi,
I'm building emacs from the trunk tree and am seeing this problem:
   1621 /sdi1/exphome/clipper/export/home/tools/emacs/trunk/lib-src/movemail.c:233: undefined reference to `mmdf_init'
   1622 /sdi1/exphome/clipper/export/home/tools/emacs/trunk/lib-src/movemail.c:361: undefined reference to `lk_open'
   1623 /sdi1/exphome/clipper/export/home/tools/emacs/trunk/lib-src/movemail.c:473: undefined reference to `lk_close'
   1624 collect2: error: ld returned 1 exit status
   1625 Makefile:357: recipe for target 'movemail' failed
   1626 make[1]: *** [movemail] Error 1

Am I doing something wrong or is this a bug?
Regards,
George...

bug#20308: Problem building emacs trunk on Fedora 21 x86_64

Thanks for reporting the bug.  It looks like you ran the 'configure' script with 
the argument '--with-mmdf'.  This doesn't work on Fedora 21, and as far as I 
know doesn't work on any currently-supported Emacs platform.  Support for 
MMDF-based MTAs was removed from GNU mailutils and related software years ago. 
I expect we should remove it from Emacs too, as it's causing configuration-time 
trouble.  I installed the attached patch, which should fix the problem, and am 
marking this bug as done.

Hmm, I regularly build the GNU Emacs master on Fedora 21 x86-64, and I don't run 
into the problem.  What happens if you build as follows?  Get a fresh checkout 
from the master, and then run:

./autogen.sh
./configure CFLAGS='-g3 -O0'
make

If this doesn't work for you, please email us what it outputs.  If it crashes 
the same way as before, please do this:

cd src
gdb temacs
(gdb) run --batch --load loadup bootstrap
(gdb) backtrace
