Issues building numpy 2.1.1 with classic Intel compilers #27492
Description
Describe the issue:
I am trying to compile numpy 2.1.1 from source on a platform with intel ifort/icc/icpc compilers, i.e., not the newer oneapi icx/ifx/icpx compilers. I know this is no longer supported by intel, but I've compiled previous versions of numpy with the older intel compilers before, so I thought I would give it a try. However, the compilation barfs as below. I am pasting a few instances of the error, which occurs on multiple source files. If it's true that numpy 2.1.1 can no longer be compiled with ifort/icc/icpc, then what is the last version of numpy that could be compiled with those?
Reproduce the code example:
