On hosts with a recent version of cmake (eg: 4.0.0), builds involving
host-pahole fail with the following error:
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 3.5 will be removed from a future version of
CMake.
Update the VERSION argument <min> value or use a ...<max> suffix to tell
CMake that the project does not need compatibility with older versions.
The issue can be reproduced on hosts with cmake >= 4.0.0 with commands:
cat <<EOF >.config
BR2_arm=y
BR2_cortex_a7=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_DEFCONFIG="versatile"
BR2_LINUX_KERNEL_NEEDS_HOST_PAHOLE=y
EOF
make olddefconfig
make
The issue has already fixed in the upstream project with commit
12ca11281912 ("CMakeLists.txt: Require cmake 3.5 or higher"), which is
part of version 1.28.
Upgrade pahole to get rid of this error.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
