From dfc55ace9939e1e8703ad37ddbba41aaa31cc0cb Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Tue, 21 Apr 2020 18:24:07 -0700 Subject: tools/runqslower: Ensure own vmlinux.h is picked up first Reorder include paths to ensure that runqslower sources are picking up vmlinux.h, generated by runqslower's own Makefile. When runqslower is built from selftests/bpf, due to current -I$(BPF_INCLUDE) -I$(OUTPUT) ordering, it might pick up not-yet-complete vmlinux.h, generated by selftests Makefile, which could lead to compilation errors like [0]. So ensure that -I$(OUTPUT) goes first and rely on runqslower's Makefile own dependency chain to ensure vmlinux.h is properly completed before source code relying on it is compiled.
