Ports RoboStack/ros-jazzy#167 by @SammyRamone: adds canopen (ros2_canopen with lely_core_libraries) to the shared selection on Linux (macOS/Windows not tried).

  • lely_core_libraries installs the lely-core autotools build into the prefix from its own build directory. The PR's patch, refreshed for 0.3.4 (jazzy, lyrical, rolling) as a shared patch; humble's 0.2.13 keeps the original.
  • The PR's c_stdlib_version change (and feat: add variant override vinca#114) isn't needed: the pinning is already glibc 2.28.

Recipe test: lely_core_libraries installs liblely-coapp and the lely/coapp headers into the prefix, which the install step of the patch is about (shared/tests/ros2-lely-core-libraries.yaml).

Built locally

  • jazzy, linux-64: lely_core_libraries, canopen and all canopen packages (core, interfaces, base/proxy/402 drivers, …); recipe tests not run (that build host needed --test skip, see Add Kinova Kortex and the Gen3 MoveIt configs (linux-64) #113).
  • rolling, linux-aarch64 (refreshed 0.3.4 patch): lely_core_libraries, canopen and all canopen packages, with their recipe tests.
  • humble, linux-64: lely_core_libraries 0.2.13 failed with GCC 15 (its older lely commit uses ATOMIC_VAR_INIT, removed in C23, and trips the new -Wunterminated-string-initialization under lely's -Werror); fixed in humble's patch, rebuild pending.
  • lyrical: building.

Prepared and built on top of the current rosdistro syncs (#62 humble, #61 jazzy, #60 lyrical, #99 rolling) merged together, so it targets their package versions: merge after them. CI is held with [skip ci] until the syncs are in.

humble's lely_core_libraries 0.2.13 builds an older lely commit
(fb735b79), and GCC 15 rejects it: C23, its default, removed
ATOMIC_VAR_INIT (spscring.h), and the new -Wunterminated-string-initialization
fires in print.c, which lely's -Werror makes fatal. Configure lely with
-std=gnu17 and that warning not an error. jazzy, lyrical and rolling
(0.3.4) build a newer lely that the shared patch covers. humble's own
patch shadows the shared one, so the fix goes there.

…lled [skip ci]

Turns the local checks of this PR into a recipe test, so later rebuilds keep them.
