Re: [OMPI devel] errno and reentrance
Thanks Paul,
so the simplest way is to force -D_REENTRANT on Solaris, i will do that !
Cheers,
Gilles

Re: [OMPI devel] errno and reentrance
Gilles,
I responded too quickly, not thinking that this test is pretty quick and
doesn't require that I try sparc, ppc, ia64, etc.
So my results:
Solaris-{10,11}:
With "cc" I agree with your findings (need -D_REENTRANT for correct
behavior).
With gcc either "-pthread" or "-D_REENTRANT" gave correct behavior
NetBSD-5:
Got "KO: error 4 (0)" no matter what I tried
Linux, FreeBSD-{9,10}, NetBSD-6, OpenBSD-5:
Using "-pthread" or "-lpthread" was necessary to link, and sufficient for
correct results.
MacOSX-10.{5,6,7,8}:
No compiler options were required for 'cc' (which has been gcc, llvm-gcc
and clang through those OS revs)
Though I have access, I did not try compute nodes on BG/Q or Cray X{E,K,C}.
Let me know if any of those are of significant concern.
I no longer have AIX or IRIX access.
-Paul
