Marco,
can you please give the attached patch a try ?
so far, it compiles for me.
btw, i faced some issues (conflicting definitions between windows.h and
netdb.h),
did you need some patches in order to solve these issues ?
Cheers,
Gilles

It is a blocking issue for any effort to move on
further cygwin release after 1.10.7

Hi,
restarting the effort to build 2.1.2 on cygwin I hit:

warning: implicit declaration of function ‘syscall’
[-Wimplicit-function-declaration]
#define memory_patcher_syscall syscall
I tried with configuration
--disable-mca-dso \
--disable-sysv-shmem \
--enable-cxx-exceptions \
--with-threads=posix \
--without-cs-fs \
--with-mpi-param_check=always \
--enable-contrib-no-build=vt,libompitrace \
--enable-mca-no-build=paffinity,installdirs-windows,timer-windows,shmem-sysv,patcher
but it is not effective.
I would expect that of directories
opal/mca/memory/base
opal/mca/memory/malloc_solaris
opal/mca/memory/patcher
only base is build and the other two : patcher and malloc_solaris,
are skipped as the conditions are not met.
Suggestion/Workaround ?
Regards
Marco
