Description

examples-v2 doesn't build for qemuppc. both_hello fails because of something going on with rtems-ld. Taking that out of the wscript results in getting further but fails with an undefined error for the same symbol.

/home/joel/rtems-work/tools/5/bin/powerpc-rtems5-gcc: hello-deep.o: In function `wrapThread_Life_action_handler':

The score thread definition files have not been updated after a change in the score:

https://git.rtems.org/rtems-tools/tree/linkers/rtems-score-thread.ini#n8

which is referenced from:

https://git.rtems.org/examples-v2/tree/hello/both_hello/hello-deep.ini#n21

I am OK with a change to remove the definition being pushed.

Note, adding libdwarf support to rtems-tools would remove the need for these files.

Please remember rtems-tools repo changes require an RSB update to have the RSB pick up any changes.

In 7045cc3/rtems-tools:

linkers: Remove _Thread_Life_action_handler

This is a static function.

Update #3413.

Resolution: fixed
Status: assignedclosed

I was able to build the examples with these patches.

It really would be better to have dynamic loading examples in rtems-examples rather than just bolting on some odd build stuff to an unrelated example. Neither both_hello or triple_period are intended to demonstrate dynamic loading and don't use it.
