From 8da20e3fe2a544979922cea457de3031aa74d64c Mon Sep 17 00:00:00 2001 From: Dominique Martinet Date: Sat, 20 Jul 2024 20:38:37 +0900 Subject: meson: fix missing failure if bpf-framework was enabled If building with clang and clang does not support bpf, then enabling -Dbpf-framework=enabled would silently drop the feature (even printing bpf-framework: enabled in the meson build recap, and no message anywhere that'd hint at the failure!) This is unexpected, so add check to fail hard in this case. All other code paths (gcc, missing bpftool) properly check for the option, but it is not as easy for a custom command so check explicitly --- meson.build | 3 +++ 1 file changed, 3 insertions(+) (limited to 'meson.build') diff --git a/meson.build b/meson.build index 3893a9fabe..e0bbb6a908 100644 --- a/meson.build +++ b/meson.build @@ -1102,6 +1102,9 @@ else # Check if 'clang -target bpf' is supported. clang_supports_bpf = run_command(clang, '-target', 'bpf', '--print-supported-cpus', check : false).returncode() == 0 endif + if bpf_framework.enabled() and not clang_supports_bpf + error('bpf-framework was enabled but clang does not support bpf') + endif elif bpf_compiler == 'gcc' bpf_gcc = find_program('bpf-gcc', 'bpf-none-gcc', -- cgit v1.2.3
