bpftool: Use gcc instead of clang compiler

2025-09-05T16:12:33+00:00

While compiling bpftool with clang, it fails with below error: | error: no member named 'id' in 'struct bpf_link' | return BPF_CORE_READ((struct bpf_link *)ent, id); bpftool is kernel tool to inspect and manipulate eBPF programs and maps. And kernel is built using GCC by default. Maintaining compatibility with Clang is an ongoing challenge, and using Clang solely for building bpftool is ineffective unless the entire kernel is compiled with Clang. Hence, updated TOOLCHAIN of bpftool to gcc. Signed-off-by: Deepak Rathore

perf: Use gcc as default compiler

2025-08-28T16:48:56+00:00

Since its being build from kernel sources which are procecced with gcc by default KERNEL_CC is gcc, its a constant battle to keep this compiling with clang, so unless clang is also used to compile kernel this is a fruitless excercise to use clang just for perf.

nonclangable: remove '-mbranch-protection=standard' globally on aarch64

2024-08-21T20:26:58+00:00

On aarch64 the handling of runtime exception is broken when build with clang. There is currently a fix for libcxx on the layer but it is not enough and this same fix needs to be applied globally. First fix attempt just include libcxx: https://github.com/kraj/meta-clang/issues/963 https://github.com/kraj/meta-clang/pull/968 Remaining reported issue: https://github.com/kraj/meta-clang/issues/998 Signed-off-by: Jose Quaresma (cherry picked from commit ee30860682fd7ec7cf95aabf794ac43976d69567) Signed-off-by: Jose Quaresma
