[zeromq-dev] problems building on GNU+Linux

[Marco Maggi]

Ciao,

  I am  new to 0MQ; I am  trying to build it  with the final
purpose  of writing  a language  binding; my  platform  is a
i686-pc-linux-gnu,  Slackware Linux, GCC  4.5.0.  I  want to
signal a couple of problems.

  The README file  coming with "zeromq-2.0.10.tar.gz" refers
to an INSTALL file which is not in the distribution, so I am
trying to make the instructions at [1] be enough for me.

  While running  "configure" the UUID  library is recognised
but while compiling I get the error:

libtool: link: g++ -g -O2 -o .libs/local_lat local_lat.o  ../src/.libs/libzmq.so /usr/local/lib/libuuid.so -lpthread
../src/.libs/libzmq.so: undefined reference to `uuid_generate'
../src/.libs/libzmq.so: undefined reference to `uuid_unparse'
collect2: ld returned 1 exit status

  I   have  installed   OSSP  UUID[2]   from   source  under
"/usr/local"   and   it  comes   with   both  "uuid.h"   and
"libuuid.so";  I gather  that this  is not  the  library 0MQ
wants, but nevertheless the Autoconf test picks it up: it is
not specific enough.  I  see in "configure.in" that the test
looks  for  "main"  while  the  test for  Cygwin  looks  for
"uuid_generate":  looking for this  function on  Linux, too,
should work.

  I also have a  "uuid.h" and "libuuid.so" under "/usr"; the
header file  attributes the copyright to  Theodore Ts'o, and
on Slackware  it comes  in the util-linux-ng  package[3]; it
looks like  this is  the needed library,  yes?  To  make 0MQ
find it I have to compile with:

    $ ./configure \
        CPPFLAGS=-I/usr/include \
        LDFLAGS=-L/usr/lib

maybe this conflict can be documented somewhere?

  With  this it builds  and "ldd"  shows that  the installed
libzmq library will find the correct libuuid (I will compile
some test program tomorrow, when the sun is up).

TIA
