*** I am hitting the mailing list with two questions because I’m not sure<br class="">
they’re sufficiently related to be in the same email. Much of this information<br class="">
will be the identical between them, but the traces will be different. ***<br class="">
<br class="">
I am trying to build the simplest of demo applications from the Robot Operating<br class="">
System (ROS) on top of RTEMS.<br class="">
<br class="">
I have a .c file (talker_init.c) that contains my Init function and a .cpp file<br class="">
(talker.cpp) that contains a function creating a ROS talker (just looping “hello<br class="">
world [counter value]”). The Init function in the .c file calls the talker<br class="">
function in the .cpp file.<br class="">
<br class="">
The ROS libraries rely on Boost libraries. I think I’ve figured out how to get<br class="">
waf to find them (at least, that’s not where I appear to have problems).<br class="">
<br class="">
My 'waf configure' command seems to complete without error.<br class="">
<br class="">
When I 'waf build -v’, I get a slew of errors associated with things being out<br class="">
of scope for boost. I’ve copied two such traces below. I can build this just<br class="">
fine when I’m not cross-compiling for RTEMS.<br class="">
<br class="">
I am using MacO Catalina 10.15.2 on a MacBook Pro.<br class="">

<div>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).</div>
<div><br class="">
</div>
<div>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.</div>
<div><br class="">
</div>
<div>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.</div>
