Hi
I had a working set up consisting of a main program (F77) that calls a bunch of subroutines in a library. Suddenly, it appears that the library is not rebuilding - changes to the main program are implemented but those to a subroutine,“reader” in folder “util”, do not. The library builds without any errors and a new library archive is created via the following makefile (rewritten for easier reading):
FOR=ifort -c -O3
LINK=ifort
MY_DIR=/mydir
UTIL=$(MY_DIR)/util
(ditto many other subroutines)
.f.o:
$(FOR) $<
.c.o:
$(CC) $<
clean:
rm -f *.o *~ core
libmy:
rm libmy.a
$(FOR) $(UTIL)/*.f
(ditto manyother subroutines)
ar -rv $(MY_DIR)/libmy.a *.o
rm *.o
Then the main program (and others) are compiled with another makefile. Again, there are no errors and a new executable is created.
FOR=ifort -c -O3
LINK=ifort
MY_DIR=/mydir
LIBMY=-L$(MY_DIR) -lmy
.f.o:
$(FOR) $(OPT) $<
.c.o:
$(CC) $(OPT) $<
my_main.o: my_main.f
$(FOR) my_main.f
my_main: my_main.o
$(LINK) -o my_main my_main.o $(LIBMY)
(ditto many other subroutines)
These makefiles used to work and have never changed, the only thing that has changed is the subroutine “reader”.
How can this be fixed?
