The configurations that have:
- BR2_ENABLE_RUNTIME_DEBUG=y
- One of BR2_FORTIFY_SOURCE_xyz=y
Currently fail to build, as libzenoh-pico's build system forces -O0
when BR2_ENABLE_RUNTIME_DEBUG=y, but -O0 builds aren't compatible with
_FORTIFY_SOURCE, causing:
../../../per-package/libzenoh-pico/host/mips64-buildroot-linux-gnu/sysroot/usr/include/features.h:422:4: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp]
422 | # warning _FORTIFY_SOURCE requires compiling with optimization (-O)
| ^~~~~~~
cc1: all warnings being treated as errors
We fix this by adding a patch that drops the forced -O3 (release
builds) and -O0 (debug builds) from the project CMakeLists.txt.
This issue exists since libzenoh-pico was introduced in Buildroot in
commit
a96361901d ("package/libzenoh-pico: new
package"), but was hidden by other issues until a first occurence in
November 2024 right after the bump to 1.0.1:

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
