79 Illegal Instruction (core dumped) $COMMAND

[ronangarrison]

When running the following code in WSL (Ubuntu 18.04), I get an error:

antsRegistrationSyN.sh -d 2 -f temp1.nii -m temp2.nii -o output

The command calls ants Registration and then in the antsRegistrationSyN.sh script on line 606 there is the illegal instruction and core dumping error. I checked memory and it doesn't appear to be a faulty memory issue. I also don't think it is an overheating issue.

Any suggestions would be greatly appreciated.

Related? Different system I know.

To be clear, the devs believe the issue is that your CPU is older than corei7, which is what our default "arch" setting is:
/CMake/ITKSetStandardCompilerFlags.cmake@master#L245

You can adjust this by adding "-march=native" to your compile options.
