Simply add support for passing STATIC=1 while building to build the tool statically. Signed-off-by: Nikolay Borisov <nborisov@xxxxxxxx> --- Currently the bpftool being distributed as part of libbpf-tools under bcc project is dynamically built on a system using GLIBC 2.28, this makes the tool unusable on ubuntu 18.04 for example. Perhaps after this patch has landed the bpftool in bcc can be turned into a static binary. tools/bpf/bpftool/Makefile | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/tools/bpf/bpftool/Makefile b/tools/bpf/bpftool/Makefile index 83369f55df61..835621e215e4 100644 --- a/tools/bpf/bpftool/Makefile +++ b/tools/bpf/bpftool/Makefile @@ -13,6 +13,10 @@ else Q = @ endif +ifeq ($(STATIC),1) + CFLAGS += --static +endif + BPF_DIR = $(srctree)/tools/lib/bpf ifneq ($(OUTPUT),) -- 2.25.1Why not just pass the flag on the command line?

Yeah, this also works, I initially thought that overriding a variable on the command line would require having the override directive in the makefile but apparently is not the case. I guess this patch can be scratched.
