[Wien] w2w compilation problem during siteconfig

[Fecher, Gerhard]

Hallo Elias,
thanks for the answers.

Meanwhile I checked, the error does not appear with GNU make 4.0
seems we should update our Cluster a little bit, I have to check which of our Computers are affected.

Personally I like more to tell make which files I like to have compiled instead of using an automatic 
search and the makefile decides which ones I like to have compiled, 
but maybe I am just a little bit too old fashioned.

Ciao
Gerhard

My memory may be feeble, but the Internet remembers All.

It turns out that I had this exact problem three years ago.  I even
asked a question about it on StackOverflow [1], where a helpful user
pointed out that this is a known bug in make 3.82 [2] and suggested the
solution

.SECONDEXPANSION:

%.o: $$(wildcard %.[fF])
    $(FC) $(FFLAGS) -c $< -o $@

(splitting the rule should still also work, of course).

Since this problem was fixed in later versions of make and is easy to
circumvent if you are affected, I will leave my Makefiles as they are.

It remains a puzzle though that I cannot now reproduce the problem with
make 3.82 (neither with a make 3.81 that I found elsewhere).  Maybe
RedHat backported the fix?  ‘make -v’ says

GNU Make 3.82
Built for x86_64-redhat-linux-gnu
