Bug Description

This happenes on Cygwin + Windows x86, Windows 7, Gearman
version 1.1.0 Wed Sep 5 08:33:37 PDT 2012

I have gone through the instruction:
http://www.phpvs.net/2010/11/30/installing-gearman-and-gearmand-on-windows-with-cygwin/

And stopped on the make for gearman:

  CXX libgearman/libgearman_libgearman_la-worker.lo
  CXX libgearman/libgearman_libgearman_la-pipe.lo
  CXXLD libgearman/libgearman.la
libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin shared libraries
  CXX libtest/libtest_libtest_la-dns.lo

I've got the current stable version of gearmand working in Windows using cygwin. The only references to spawn.h are in libtest, which is not needed for a working installation. To get it to compile, I made the following changes to /Makefile.am :

39c39
< include libtest/include.am
---
> # include libtest/include.am
52c52
< include tests/include.am
---
> # include tests/include.am

I also needed to edit thread.cc in libgearman-server to allow for the unsupported pthread_attr_setscope in cygwin:

391,392c391,395
< (void) pthread_attr_destroy(&attr);
< return gearmand_perror(error, "pthread_attr_setscope");
---
> if (error != 134)

> (void) pthread_attr_destroy(&attr);
> return gearmand_perror(error, "pthread_attr_setscope");
> }

I then reran:
aclocal -I m4
autoconf
automake
./configure
make
make install

Because I was missing some of the dependencies (Sphinx, Postgresql, TokyoCabinet and Memcached), automake complained at me and so I also had to comment out those .am files as needed to get automake to run. There may be a better way of doing this, but otherwise automake complained that the relevant items weren't in AM_CONDITIONAL.

I've tested out gearmand and have used gearman to act as a client and worker on both the same machine and using a Ubuntu VM to connect to the Windows hosted gearman server.

In the long term, it would be better to address the problems with libtest to allow it to run without spawn.h, but that's beyond my current understanding.
