I am trying to build the simplest of demo applications from the Robot Operating
System (ROS) on top of RTEMS.
I have a .c file (talker_init.c) that contains my Init function and a .cpp file
(talker.cpp) that contains a function creating a ROS talker (just looping “hello
world [counter value]”). The Init function in the .c file calls the talker
function in the .cpp file.
The ROS libraries rely on Boost libraries. I think I’ve figured out how to get
waf to find them (at least, that’s not where I appear to have problems).
My 'waf configure' command seems to complete without error.
When I 'waf build -v’, I get a slew of errors associated with things being out
of scope for boost. I’ve copied two such traces below. I can build this just
fine when I’m not cross-compiling for RTEMS.
I am using MacO Catalina 10.15.2 on a MacBook Pro.
Nice.
I have added my own project directory within the rtems-examples repository and
effectively copied a wscript file from another example project, so I’m still
relying on the top-level wscript file and the additional elements in the
rtems_waf directory.
Sure.

This looks like a host file and not and RTEMS. Do you have an RTEMS build of
boost installed somewhere?
Nope! Seems like a pretty fundamental problem.
I’ll try it and report back.
Has it been done? Any tips/tricks/pointers/pitfalls?
Most of Boost is header-only, so it shouldn’t require an RTEMS-specific build. I *have* been able to go back and build some of the Boost libraries that do require compilation (e.g., MPI).
In any case, the problem in this email thread associated with ‘assert’ and the problem reported in a separate email thread with ‘locale_facets_nonio.h’ declaration issues involve two of the header-only libraries. I’ve copied snippets of my current errors in both cases below.
The ‘locale_facets_nonio.h’ is triggered directly from an RTEMS header file, whereas the assert error doesn’t seem to touch RTEMS files at all, though it builds just fine when I’m not cross-compiling.
