Unfortunately, the BaseTools makefile(s) aren't granular enough for this. They don't track dependencies well enough, at the individual tool level. The above command would fail: ------- make: Entering directory `/home/lacos/src/upstream/edk2/BaseTools/Source/C/EfiRom' mkdir ../bin gcc -c -I .. -I ../Include/Common -I ../Include/ -I ../Include/IndustryStandard -I ../Common/ -I .. -I . -I ../Include/X64/ -MD -fshort-wchar -fno-strict-aliasing -Wall -Werror -Wno-deprecated-declarations -Wno-stringop-truncation -Wno-restrict -Wno-unused-result -nostdlib -g -O2 EfiRom.c -o EfiRom.o gcc -o ../bin/EfiRom EfiRom.o -L../libs -lCommon /usr/bin/ld: cannot find -lCommon collect2: error: ld returned 1 exit status ------- > >> >> slof: >> $(MAKE) -C SLOF CROSS=$(powerpc64_cross_prefix) qemu >> @@ -150,6 +148,7 @@ clean: >> $(MAKE) -C sgabios clean >> rm -f sgabios/.depend >> $(MAKE) -C ipxe/src veryclean >> + $(MAKE) -C edk2/BaseTools clean > > Ditto. > >> $(MAKE) -C SLOF clean >> rm -rf u-boot/build.e500 >> $(MAKE) -C u-boot-sam460ex distclean >> > > Whichever path used: > Reviewed-by: Philippe Mathieu-Daudé <phi...@redhat.com> > Tested-by: Philippe Mathieu-Daudé <phi...@redhat.com> > thanks!
