From: Christian Marangi Date: Fri, 3 May 2024 12:49:58 +0000 (+0200) Subject: bpf: fix broken inclusion of system include X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fc221b065a94dbd9c11218a777a86c1bcdc69ee5;p=openwrt%2Fstaging%2Fthess.git bpf: fix broken inclusion of system include Commit d82c5884c616 ("treewide: make use of new toolchain define") changed $(TOOLCHAIN_DIR)/include to the new variable $(TOOLCHAIN_INC_DIRS) that now can contain multiple entry. Because of this only the first include in $(TOOLCHAIN_INC_DIRS) was actually included with -isystem, making the other producing warning with ignored inputs. Fix this by parsing each entry in $(TOOLCHAIN_INC_DIRS) and adding the -isystem prefix to correctly include them in the BPF_KERNEL_INCLUDE.
