The protobuf support breaks the build, as protobuf includes
libabseil-cpp headers, which now require C++14. opencv3 doesn't have
any ENABLE_CXX14 option, so for the time being, disable protobuf
support until someone bothers enough to fix this up.
While we suspect a libabseil-cpp version bump to be responsible for
the issue, we are not 100% sure. However, the issue is definitely
present in Buildroot 2025.02.x, as it can be reproduced using the
following defconfig:
BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_PACKAGE_OPENCV3=y
BR2_PACKAGE_OPENCV3_LIB_SHAPE=y
BR2_PACKAGE_OPENCV3_LIB_STITCHING=y
BR2_PACKAGE_OPENCV3_LIB_SUPERRES=y
BR2_PACKAGE_OPENCV3_LIB_TS=y
BR2_PACKAGE_OPENCV3_LIB_VIDEOSTAB=y
BR2_PACKAGE_OPENCV3_WITH_PROTOBUF=y

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.
