<div dir="ltr">You might be interested in some of the patches I've got sitting in <a href="http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=ross/mutb">http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=ross/mutb</a> specifically around "Add new ELF parser". This adds a fully-featured Python ELF parser to lib/oe which could be used to inspect the binaries the way file does, but without having to call and parse the output of file.<div><br></div><div>Ross</div></div><div class="gmail_extra"><br><div class="gmail_quote">On 1 December 2017 at 15:50, Olof Johansson <span dir="ltr"><<a href="mailto:olof.johansson@axis.com" target="_blank">olof.johansson@axis.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Avoid matching substrings that are picked up from paths, for instance.<br>
Do this by anchoring the tokens we look for (e.g "executable" or "not<br>
stripped") with whitespace and punctuation.<br>
<br>
Submitted with this patch series is a change that adds the use of<br>
--brief to file. This removes the path prefix to the output, but the<br>
path can still be included in shebang lines (which file will report as<br>
something like "a /foo/bar/baz.py script").<br>
