Marco,
Thanks for the patch, i will apply the changes related to the missing
include files to master and PR to v2.x
on linux, libpmix.so does not depend on libopen-pal.
that being said, libpmix.so has undefined symbols related to hwloc and
libevent, and these symbols are defined in libopen-pal.so
i assume that is ok with linux but cygwin does not accept it.
an other way to do things (and generally speaking, that could become the
way to go in a near future) is to use external hwloc and libevent (that
assumes of course cygwin provides these libraries and versions meet the
ompi requirements)
could you try to
configure --with-hwloc=external --with-libevent=external ...
and see if it helps ?
fwiw, with master you will soon be able to do the same thing with pmix
(e.g. configure --with-pmix=external ...)
Cheers,
Gilles

building 2.0.0rc1 on cygwin I was stacked on
opal/mca/pmix/pmix1xx/pmix
Question:
- as pmix depends on hwloc and libevents, is it supposed to
link against opal shared lib, is it supposed to be included
in the opal shared lib or is it a circular dependency ?
I solved the build changing from shared to convenience library.
-lib_LTLIBRARIES = libpmix.la
+noinst_LTLIBRARIES = libpmix.la
as circular dependency will be a hell to manage with the
no-undefined flag.
The attached patch solves also
- several lacks of declaration for opal_output functions
used in the ompi tree.
They also require libmpi link vs lib@opal_lib_pre...@open-pal.la
- lack of declaration for several <unistd.h> functions
like access, gethostname, usleep, ..
- add !defined(__CYGWIN__) on libevent2022/libevent/event.h
as for current 1.8 and 1.10 code.
Please also note that usleep is marked as obsolescent on
Open Group Base Specifications Issue 6
http://pubs.opengroup.org/onlinepubs/009695399/functions/usleep.html
and it is missing on Issue7
With this patch it builds on cygwin 64 bit and passes the
same tests of 1.10.x code
Regards
Marco
