I wasn't suggesting you send your makefile: we don't have the time or energy to understand and debug an entire make environment :). I was suggesting you create a small sample that reproduces the problem you're seeing and send that. I tried to create a repro case based on your description but it worked fine for me with both GNU make 4.1 and 4.2.1: $ mkdir -p build/common/tests ../common/tests $ echo 'int main() { return 0; }' > ../common/tests/timer_test.cpp $ cat Makefile all: build/common/tests/timer_test build/common/tests/timer_test: build/common/tests/timer_test.o # ----- DEPFLAGS = -MT $@ -MMD -MP -MF $(@:.o=.Td) COMPILE.cc = $(CXX) $(DEPFLAGS) $(CXXFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c POSTCOMPILE = mv -f $(@:.o=.Td) $(@:.o=.d) build/% : build/%.o $(LINK.cc) -o $@ $^ build/common/%.o : ../common/%.cpp build/common/%.d $(COMPILE.cc) $(OUTPUT_OPTION) $< $(POSTCOMPILE) build/common/%.d: ; .PRECIOUS: build/common/%.d -include build/common/tests/timer_test.d $ make -r g++ -MT build/common/tests/timer_test.o -MMD -MP -MF build/common/tests/timer_test.Td \ -c -o build/common/tests/timer_test.o ../common/tests/timer_test.cpp mv -f build/common/tests/timer_test.Td build/common/tests/timer_test.d g++ -o build/common/tests/timer_test build/common/tests/timer_test.o $ make -r make: Nothing to be done for 'all'. $ rm -f build/common/tests/timer_test.d $ make -r g++ -MT build/common/tests/timer_test.o -MMD -MP -MF build/common/tests/timer_test.Td \ -c -o build/common/tests/timer_test.o ../common/tests/timer_test.cpp mv -f build/common/tests/timer_test.Td build/common/tests/timer_test.d g++ -o build/common/tests/timer_test build/common/tests/timer_test.o _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
