BUG: svml check in numpy/core/setup.py does not work when cross-compiling #20736
Description
Describe the issue:
numpy/core/setup.py performs the following:
def can_link_svml():
"""SVML library is supported only on x86_64 architecture and currently
only on linux
"""
machine = platform.machine()
system = platform.system()
return "x86_64" in machine and system == "Linux"
This really does not work when compiling on x86_64 host for something entirely different, e.g. arm or risc-v, as it enables svml with subsequent build failure.
If this can't be easily auto-detected, there should be at least a command line switch to selectively enable/disable this.
Reproduce the code example:
This is a configuration/build issue.Error message:
Here's how the build fails:
