I installed intel oneapi compiler, then use icx and icpx to compile and install openmpi software (openmpi-4.1.5) by specifying “CC=icx” and “CXX=icpx”.
However, the installed “openmpi” can not be used to compile the MPI codes.The same process, no errors occurred on Linuxmint system. What is the problem?
(1) The error is as follows:
/usr/bin/ld: /opt/eos/cgp-1.6_icx/lib/libcgp.a(add_hamming_win.o): in function add_hamming_win_1d1(int, int, int, int, int, cgp_complex*)': add_hamming_win.cc:(.text+0x20b): undefined reference to _intel_fast_memset’
/usr/bin/ld: add_hamming_win.cc:(.text+0x239): undefined reference to `_intel_fast_memset’
Here, ‘add_hamming_win_1d1’ is a subroutine in my own code.
(2) when I check the “mpicxx -v” command, I got the messages. The installed “openmpi” looks like based on gcc.
