compile with the x86_64 toolset to surface any features the tools may be<br>
missing. Here's an error I came across:<br>
<br>

x86_64-rtems5-gcc: error: unrecognized command line option '-qnolinkcmds'<br>
Makefile:484: recipe for target 'dirutils.rel' failed<br>
<br>
From previous correspondence[1], it seems like rtems.h in gcc is relevant -<br>
rtems-tools built x86_64-rtems5-gcc v7.2.0 and that does include rtemself.h<br>
here[2][3], which contains the same content as I expected from the rtems.h<br>
for other architectures[4].<br>
<br>
Joel, do you have any thoughts off the top of your head? I'll continue<br>
looking into it, but any background information I may be missing would be<br>
useful.<br>
<br>
Thanks!<br>
