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:
