Thanks Mr Heinz for responding. It maybe the case with clang, but doing a intel setvars.sh then issuing the following compile gives me the message:
[root@jean-r8-sch24 openmpi-4.1.0]# icc icc: command line error: no files specified; for help type "icc -help" [root@jean-r8-sch24 openmpi-4.1.0]# icc -v icc version 2021.1 (gcc version 8.3.1 compatibility) [root@jean-r8-sch24 openmpi-4.1.0]# Would lead me to believe that icc is still available to use. This is a government contract and they want the latest and greatest.

TBH - I think that icc isn't included with the latest release of oneAPI, I think they've switched to including clang instead. I had a similar issue to yours but I resolved it by installing a 2020 version of the Intel HPC software. Unfortunately, those versions require purchasing a license. -----Original Message----- From: users <users-boun...@lists.open-mpi.org> On Behalf Of bend linux4ms.net via users Sent: Tuesday, March 30, 2021 12:42 PM To: Open MPI Open MPI <users@lists.open-mpi.org> Cc: bend linux4ms.net <b...@linux4ms.net> Subject: [OMPI users] Newbie With Issues Hello group, My name is Ben Duncan. I have been tasked with installing openMPI and Intel compiler on a HPC systems. I am new to the the whole HPC and MPI environment so be patient with me. I have successfully gotten the Intel compiler (oneapi version from l_HPCKit_p_2021.1.0.2684_offline.sh installed without any errors. I am trying to install and configure the openMPI version 4.1.0 however trying to run configuration for openmpi gives me the following error: ============================================================================ == Configuring Open MPI ============================================================================ *** Startup tests checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu checking for gcc... icc checking whether the C compiler works... no configure: error: in `/p/app/openmpi-4.1.0': configure: error: C compiler cannot create executables See `config.log' for more details With the error in config.log being: configure:6499: $? = 0 configure:6488: icc -qversion >&5 icc: command line warning #10006: ignoring unknown option '-qversion' icc: command line error: no files specified; for help type "icc -help" configure:6499: $? = 1 configure:6519: checking whether the C compiler works configure:6541: icc -O2 conftest.c >&5 ld: cannot find -lstdc++ configure:6545: $? = 1 configure:6583: result: no configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "Open MPI" | #define PACKAGE_TARNAME "openmpi" | #define PACKAGE_VERSION "4.1.0" | #define PACKAGE_STRING "Open MPI 4.1.0" | #define PACKAGE_BUGREPORT "https://nam11.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.open-mpi.org%2Fcommunity%2Fhelp%2F&data=04%7C01%7Cmichael.william.heinz%40cornelisnetworks.com%7C452071550e3c40842a6008d8f39b1ab4%7C4dbdb7da74ee4b458747ef5ce5ebe68a%7C0%7C0%7C637527194795401887%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=MqdORKp%2Fbf6mS7NQ51RjPUe0WVVcBITwP0HpxpYyBjI%3D&reserved=0" | #define PACKAGE_URL "" | #define OPAL_ARCH "x86_64-unknown-linux-gnu" | /* end confdefs.h. */ | | int | main () | { | | ; | return 0; | } configure:6588: error: in `/p/app/openmpi-4.1.0': configure:6590: error: C compiler cannot create executables See `config.log' for more details My configure line looks like: ./configure --prefix=/p/app/compilers/openmpi-4.1.0/openmpi-4.1.0.intel --enable-wrapper-rpath --disable-libompitrace --enable-mpirun-prefix-by-default --enable-mpi-fortran SO what am I doing wrong , or is it something else ?
