Hello,
sadly I get an error message during compiling unison:
make tags
tail: `-1′ option is obsolete; use `-n 1′
Try `tail –help’ for more information.
tail: `-1′ option is obsolete; use `-n 1′

if [ -f `which etags` ]; then \
etags *.mli */*.mli *.ml */*.ml */*.m *.c */*.c *.txt \
; fi
/bin/sh: etags: not found
make[1]: [tags] Error 127 (ignored)
Any idea why?
Best regards
Martin

   I came across this error as well when compiling for x86. Build still produced a usable executable. Others have had the same result: http://tech.groups.yahoo.com/group/unison-users/message/9607

     I run into the same error:

     make tags

     if [ -f `which etags` ]; then \
     etags *.mli */*.mli *.ml */*.ml */*.m *.c */*.c *.txt \

       This is an interpreter failure… change it to the newer format

   Just wanna say a big thank you! Your very simple but essential instructions helped my to set up sync between 2 Synology Diskstations.
   Have a good time,
   greetings from Vienna!

   hello

   i had to install
   # ipkg install ncurses
   as well.

   i’ve compiled unison version 2.40.102 on a DS213+. this model is equipped with a PPC cpu, thus the above mentioned directory /opt/arm-none-linux-gnueabi is equivalent to the directory /opt/powerpc-linux-gnuspe as it is found on this system.

   so instead of
   # sudo rm /opt/arm-none-linux-gnueabi/lib/libpthread.so.0
   # sudo ln -s /lib/libpthread.so.0 /opt/arm-none-linux-gnueabi/lib/

   i run (as root):
   # rm /opt/powerpc-linux-gnuspe/lib/libpthread.so.0
   # ln -s /lib/libpthread.so.0 /opt/powerpc-linux-gnuspe/lib/

   but i found additional libraries that had invalid refernces. so i did the same for libm and libdl:
   # rm /opt/powerpc-linux-gnuspe/lib/libm.so.6
   # ln -s /lib/libm.so.6 /opt/powerpc-linux-gnuspe/lib/
   # rm /opt/powerpc-linux-gnuspe/lib/libdl.so.2
   # ln -s /lib/libdl.so.2 /opt/powerpc-linux-gnuspe/lib/

   additionally i had to do a similar workaround for libncurses:
   # rm /opt/lib/libncurses.so.5
   # ln -s /lib/libncurses.so.5 /opt/lib

   the error with the ‘etags” appeared as well. i just ignored it. the unison-binary created worked well.

   regards,
   martin.

   ipkg install ocaml make gcc textutils

   Thank you! I ALMOST got it to work on a DS1513+ with the latest DSM 5.
   I compiled, but it was segfaulting. Out of desperation I tried to compile on my laptop (Ubuntu 14.04) copied the executable, and copied libtinfo.so.5 from my /usr/lib64 to /lib64 on the NAS.
   It just works!

   On DSM 5 I have some trouble.

   1) ln on libpthread
   The directory “/opt/arm-none-linux-gnueabi” depend on processor with intel it must be “”

   2) Makefile.Ocaml prepend we have “emacs”
   Makefile.Ocaml use “etags” and “etags” is a part of emacs so we must install it with:
   sudo ipkg install emacs22

   3) Makefile.Ocaml use “tail -1”
   and this use is obsolete. So We must modify the file from “tail -1” to “tail -n 1” (3 occurs)

   4) Makefile.Ocaml refer “bash”
   On line 324, we have:
   # ifeq ($(shell echo type -t ocamldot | bash), file)
   but my Synology rs3412 and DSM 5 only have “ash”!
   So, we must also install it or modify the Makfile…

   Finaly, the compilation seem to be ok but, like “michele”, I have a “Segmentation fault”. So, Ihave done like Michele from the unison on our Debian server…

   As this is one of the first results when googling for unison on synology, here’s some updated news: https://github.com/bcpierce00/unison/issues/290
