I had been successfully using the Fortran Linux Intel Parallel Studio XE 2019.4.070 compiler (with CodeBlocks) , when after a machine reboot, I found that when linking, the 2 intrinsic functions 'stop' and 'get_command_argument', could no longer be linked, with the error messages :-
... undefined reference to 'for_stop_core_quiet'
... undefined reference to 'for_getcmd_arg_err'
I have tried to explicitly link to 'libifcoremt.so', but I get the same errors.
No enough information here.
Are you linking static or dynamic, or do you know? Use compiler option -dryrun or -# to dump all the options and defines for the compilation.
for_getcmd_arg_err is in libifocore. The stop core looks like openMP or -parallel option??
Is tis openMP? Why libifcoremt and not libifcore?
Let's see the full compilation options you are using, especially tell me you are NOT using -fast please.
