Thanks Jeff, I have tried with openmpi-4.1.4, but I still get the same error. The main error being ../../../../../../opal/mca/event/libevent2022/libevent/signal.c:135:14: error: ‘NSIG’ undeclared (first use in this function); did you mean ‘_NSIG’? int ncaught[NSIG]; ^~~~ _NSIG But I notice that inthe file "/usr/include/x86_64-linux-gnu/asm/signal.h" there is some definition of NSIG #define NSIG 32 typedef unsigned long sigset_t; .... .... /* These should not be considered constants from userland. */ #define SIGRTMIN 32 #define SIGRTMAX _NSIG
So I am wondering if it is my system which is not picking up the correct version of signal.h I have a attached a new zipped file ompi-output-tar.bz2, which is also on dropbox, link https://www.dropbox.com/s/ps49xqximjnn8oy/ompi-output.tar.bz2?dl=0 On Tue, Sep 27, 2022 at 2:19 PM Jeff Squyres (jsquyres) <jsquy...@cisco.com> wrote: > Can you re-try with the latest Open MPI v4.1.x release (v4.1.4)?
