This helps when using a cross-compiler for building intel-speed-select, currently, its hardcoded to pick libnl3 headers from build host which may not be same as build target when cross compiling. cc -print-sysroot will print nothing if compiler is configured without a sysroot and result in same string as it is now. Fixes errors with gcc configured with host include poisoning e.g. cc1: error: include location "/usr/include/libnl3" is unsafe for cross-compilation [-Werror=poison-system-directories] Signed-off-by: Khem Raj <raj.khem@xxxxxxxxx> Cc: Srinivas Pandruvada <srinivas.pandruvada@xxxxxxxxxxxxxxx> Cc: Len Brown <len.brown@xxxxxxxxx> --- tools/power/x86/intel-speed-select/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/power/x86/intel-speed-select/Makefile b/tools/power/x86/intel-speed-select/Makefile index 7221f2f55e8b..8d3a02a20f3d 100644 --- a/tools/power/x86/intel-speed-select/Makefile +++ b/tools/power/x86/intel-speed-select/Makefile @@ -13,7 +13,7 @@ endif # Do not use make's built-in rules # (this improves performance and avoids hard-to-debug behaviour); MAKEFLAGS += -r -override CFLAGS += -O2 -Wall -g -D_GNU_SOURCE -I$(OUTPUT)include -I/usr/include/libnl3 +override CFLAGS += -O2 -Wall -g -D_GNU_SOURCE -I$(OUTPUT)include -I$(shell $(CC) -print-sysroot)/usr/include/libnl3 override LDFLAGS += -lnl-genl-3 -lnl-3 ALL_TARGETS := intel-speed-select
