<div dir="ltr">Hi Ralf,<div><br></div><div>I've never seen anything like this - the compiler generating assembly instructions that don't exist. The compiler is set to using the native architecture, but it would well be that in a virtual machine, the compiler gets confused as to what the 'native' CPU actually is. You can query what the compiler thinks your CPU is using this command:</div>
<div><br></div><div>$ gcc -march=native -Q --help=target | grep march</div><div><br></div><div>Can you run this and report back on the output?</div><div><br></div><div>As a potential workaround, you could try editing sysconf/linux.py and replace the '-march=native' option with '-march=x86-64', which is pretty generic - assuming you're running a 64-bit virtual machine. </div>
<div><br></div><div>Cheers,</div><div>Donald.</div><div><br></div><div>PS: could be that you need to put 'x86_64' - I can never remember whether it's an underscore or a hyphen...</div><div><br></div><div><br></div>
