source: rtems_waf/rtems.py @ c0d52d5

Last change on this file since c0d52d5 was c0d52d5, checked in by Chris Johns <chrisj@…>, on 08/12/18 at 01:57:31

Change RTEMS path check from bin to share/rtems<version>.

There is no bin directory anymore with RTEMS 5 so the test fails. Check
for the share/rtems<version> directory.

Closes #3500.
