These are just warning messages and library compiles and builds successfully and all the tests passed successfully. So this is more of an informational message. This is is on CentOS 7 system. The configure and make commands used are shown below, and compilation is being with the oneapi/2023.1 installed icx and ifort versions. export LDFLAGS=“-Wl,–rpath -Wl,${SZIP}/lib” $srcdir/configure CC=icx CXX=icx F77=ifort F90=ifort FC=ifort --prefix=$install\_dir --enable-fortran --with-szlib=$SZIP --enable-shared |& tee $srcdir/config-intel-`date +%F`.log-rr make -j8 |& tee $srcdir/make-intel-`date +%F`.log-rr Some of the messages are: CC H5Cdbg.lo 1 warning generated. icx: warning: -Wl,-s: ‘linker’ input unused [-Wunused-command-line-argument] warning: unknown warning option ‘-Wic-pointer’; did you mean ‘-Wregister’? [-Wunknown-warning-option] It is probably possible to silence those warnings with the appropriate flags, but just wanted to report this since this is the first time I am building with the oneapi compilers. Thank you!
