The px4_os_add_flags defined in cmake/posix/px4_impl_posix.cmake did
add (threading) libraries to added_exe_linker_flags, which subsequently
end up in CMAKE_EXE_LINKER_FLAGS and then have no effect because those
flags are passed to the linker before any of the object files and static
libraries.
Those libraries are already added correctly in the corresponding
src/firmware/*/CMakeLists.txt files (for qurt, nuttx AND posix).
I left in the non-library linker flag '-pthread' for the bebop board,
although it seems very weird to me that this is needed (is it?).
If that is needed then it seems weird to link manually (that is,
src/firmware/*/CMakeLists.txt) with -lpthread.
For linux/g++ -pthread is added to the CXXFLAGS as it should be:
this causes the compiler to define _REENTRANT which is needed
for (the interface of) certain libraries to become thread-safe.
Offically one also can just pass -pthread to the linker, which then
causes the right libraries to be linked, but just linking with
-lpthread -lm -lrt works too.
I ran into this while adding support for libcwd, which explicitly
complains that _REENTRANT isn't defined when trying to link with
the thread-safe version of libcwd (-lcwd_r) and then tells you
to use -pthread.

Or, run 'make list_vmd_make_targets' from the build_posix_* directory.
* This adds the list_cmake_targets make target to print all
cmake targets that one can match with PX4_NO_OPTIMIZATION.
PX4_NO_OPTIMIZATION is ignored (do optimization as normal)
when the CONFIG isn't posix_sitl_*.
* Add comment in Makefile on how/where to find all targets.
This allows one to set a semi-colon separated list of regular
expressions in the environment variable PX4_NO_OPTIMIZATION
to control which (cmake generated) targets should be compiled
without optimization.
Suppressing optimization can be necessary for debugging in
a debugger, especially when trying to step through the code
or needing to print variables that otherwise are optimized out.
EXAMPLE
export PX4_NO_OPTIMIZATION="px4;^modules__uORB;^modules__systemlib$"
will result in the following messages during cmake configuration:
[...]
-- Disabling optimization for target 'platforms__posix__px4_layer'
because it matches the regexp 'px4' in env var PX4_NO_OPTIMIZATION
-- Disabling optimization for target 'modules__systemlib' because it
matches the regexp '^modules__systemlib$' in env var PX4_NO_OPTIMIZATION
-- Disabling optimization for target 'modules__uORB' because it matches
the regexp '^modules__uORB' in env var PX4_NO_OPTIMIZATION
-- Disabling optimization for target 'examples__px4_simple_app' because
it matches the regexp 'px4' in env var PX4_NO_OPTIMIZATION
-- Disabling optimization for target 'modules__uORB__uORB_tests' because
it matches the regexp '^modules__uORB' in env var PX4_NO_OPTIMIZATION
-- Disabling optimization for target 'px4' because it matches the regexp
'px4' in env var PX4_NO_OPTIMIZATION
Note that a list of all (currently used) target names can be printed
with the following command line from within the required build directory:
find . -wholename '*/CMakeFiles/*.dir/flags.make' | xargs dirname | xargs basename -a | sort -u | sed -e 's/.dir$//'
While the config_sitl_rcS_dir is used more extensively (and actually
only depending on the base cmake target), the variables
config_sitl_viewer and config_sitl_debugger are just used to be
passed on for the run_config target; config_sitl_debugger is even
*always* 'disable'. Hence, they don't really need to be cached
(INTERNAL or not). Before this patch FILEPATH was used instead
of INTERNAL, but I doubt very much that that was intended. That
only makes sense when cmake-gui would be used and then would pop-up
a file browser to let the user pick a file (while really they
need to pick a directory, so it's wrong either way).
The ONLY reason caching would be used is when a developer edits
the build_posix_sitl_*/CMakeCache.txt files, changes these values
and then runs cmake in the build directory again, now overriding
the values intended here. Nevertheless, I left in the caching.
The main change in this commit (that theoretically has no real effect)
is that I removed the duplicated maintenance of
posix_sitl_broadcast.cmake. When that file was added, it was an
exact copy of posix_sitl_default.cmake and is since not always
maintained to remain the same. I don't think that difference is
in anyway relevant for the broadcasting part though.
Note that I think that something like that also holds for the
posix_sitl_replay.cmake; it would be a lot better - maintenance-wise
- when it was just derived from (or the same as) posix_sitl_default,
I think.
Over time I made a few changes unrelated to what I'm really working on.
These changes are hereby committed first. The bug fixes are related to
what I'm doing in that I need them to be fixed for future commits.
Tools/sitl_run.sh: rename label to rcS_dir and fix usage help.
cmake/common/px4_base.cmake: Remove the check on OUT_UNPARSED_ARGUMENTS,
and a few typos and indentation issues.
cmake/configs/posix_sitl_replay.cmake: Set the correct variable
(config_sitl_rcS_dir) to the correct directory.
cmake/nuttx/px4_impl_nuttx.cmake: typos and indentation issues,
and removal of a redundant FORCE (INTERNAL implies FORCE).
cmake/posix/px4_impl_posix.cmake: typos and indentation issues.
cmake/qurt/px4_impl_qurt.cmake: typos and indentation issues.
src/modules/mavlink/mavlink_ftp.cpp : possible strict-aliasing breakage.
NOTES
The second argument passed to sitl_run.sh is the value of
config_sitl_rcS_dir. This fact is missing from the usage help.
I renamed 'label' to 'rcS_dir' to better reflect this.
Also, for the 'replay' config the wrong variable was set causing
the call to sitl_run.sh to skip an argument and fail (ie the
debugger was passed as rcS_dir and so on).
The check on OUT_UNPARSED_ARGUMENTS in px4_parse_function_args
basically causes every passed IN variable to be REQUIRED and is
therefore a bug. The test for the presence of the REQUIRED arguments
follows directly after and is sufficient for this job. This bug went
unnoticed because currently every argument to OPTIONS, ONE_VALUE,
and MULTI_VALUE is actually passed to the function(s) calling
px4_parse_function_args (them being REQUIRED or not).
The changes in mavlink_ftp.cpp are to avoid a possible aliasing bug
and (mostly) to avoid the compiler warning/error: dereferencing type-
punned pointer will break strict-aliasing rules [-Werror=strict-aliasing].
