Hello<br />
<div id="signature"><br />I don't know if I have come through to the right place.<br /><br />I am trying to build criu 3.15 for Raspberry Pi zero. Compilation from source is fine but restorer.c generates an illegal instruction when criu is run. I have checked your makefile and it seems to be detecting ARM6 architecture okay. Not sure how to proceed. The error occurs at in restorer.c at this point:<br /><br />I have highlighted the ARM instruction which is throwing the error.<br /><br />--- C code ---<br />
