Hi, Nicolas (CC'd) and I are working on a small utility that does some bpf things. What it actually does isn't important. But I did just clean up its use of libbpf by way of a Makefile: > KERNEL_VERSION := 5.5.11 > PKG_CONFIG ?= pkg-config > > all: linux-$(KERNEL_VERSION)/.prepared > @$(MAKE) --no-print-directory netifexec > > linux-$(KERNEL_VERSION)/.prepared: > curl https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-$(KERNEL_VERSION).tar.xz | tar xJf - > touch $@ > > CFLAGS ?= -O3 > CFLAGS += -Ilinux-$(KERNEL_VERSION)/tools/lib/bpf -Ilinux-$(KERNEL_VERSION)/tools/include -Ilinux-$(KERNEL_VERSION)/tools/include/uapi > CFLAGS += -DHAVE_LIBELF_MMAP_SUPPORT > CFLAGS += -MMD -MP > CFLAGS += -std=gnu99 -D_GNU_SOURCE > CFLAGS += -Wall > CFLAGS += $(shell $(PKG_CONFIG) --cflags libelf zlib) > LDLIBS += $(shell $(PKG_CONFIG) --libs libelf zlib) > > netifexec: $(sort $(patsubst %.c,%.o,$(wildcard *.c linux-$(KERNEL_VERSION)/tools/lib/bpf/*.c))) > > clean: > $(RM) netifexec *.o *.d linux-$(KERNEL_VERSION)/tools/lib/bpf/*.o linux-$(KERNEL_VERSION)/tools/lib/bpf/*.d > > mrproper: clean > $(RM) -r linux-$(KERNEL_VERSION) > > .PHONY: all clean mrproper Ignoring that piping curl to tar with no hash checking is unsafe, is this kind of embedding something you intended people would do to use this code externally? Or is there another distribution of this library from elsewhere that you'd recommend? Jason
