There were probably quite a few differences from the output of "configure" between GCC 9.4 and GCC 11.3.
For example, your original post cited "/usr/lib/gcc/x86_64-linux-gnu/9/include/float.h", which, I assume, does not exist on your new GCC 11.3-based system. Meaning: if you had run make clean and then re-ran configure, it probably would have built ok. But deleting the whole source tree and re-configuring + re-building also works. 🙂 ________________________________ From: Jeffrey Layton <layto...@gmail.com> Sent: Tuesday, July 18, 2023 11:38 AM To: Jeff Squyres (jsquyres) <jsquy...@cisco.com> Cc: Open MPI Users <users@lists.open-mpi.org> Subject: Re: [OMPI users] Error build Open MPI 4.1.5 with GCC 11.3 Jeff, Thanks for the tip - it started me thinking a bit. I was using a directory in my /home account with 4.1.5 that I had previously built using GCC 9.4 (Ubuntu 20.04). I rebuilt the system with Ubuntu-22.04 but I did a backup of /home. Then I copied the 4.1.5 directory to /home again. I checked and I did a "make clean" before attempting to build 4.1.5 but with GCC 11.3 that came with Ubuntu 22.04. In fact, I did it several times before I ran configure. Even after running "make clean" I got the error I mentioned in my initial post. This happened several times. This morning, I blew away my 4.1.5 directory and downloaded a fresh 4.1.5. Configure went fine as did compiling it. My theory is that some cruft from building 4.1.5 with GCC 9.4 compilers hung around, even after "make clean". Using a "fresh" download of 4.1.5 did not include this "cruft" so configure and make all proceeds just fine. I don't know if this is correct and I can't point to any smoking gun though. Thanks!

Usually, the specific .h files that are listed as dependencies came from somewhere -- usually either part of the GNU Autotools dependency analysis. I'm guessing that /usr/lib/gcc/x86_64-linux-gnu/9/include/float.h doesn't actually exist on your system -- but then how did it get into Open MPI's makefiles? Did you run configure on one machine and make on a different machine, perchance? ________________________________ From: users <users-boun...@lists.open-mpi.org<mailto:users-boun...@lists.open-mpi.org>> on behalf of Jeffrey Layton via users <users@lists.open-mpi.org<mailto:users@lists.open-mpi.org>> Sent: Monday, July 17, 2023 2:05 PM To: Open MPI Users <users@lists.open-mpi.org<mailto:users@lists.open-mpi.org>> Cc: Jeffrey Layton <layto...@gmail.com<mailto:layto...@gmail.com>> Subject: [OMPI users] Error build Open MPI 4.1.5 with GCC 11.3 Good afternoon, I'm trying to build Open MPI 4.1.5 using GCC 11.3.
