Hello! |
| 2 |
|
| 3 |
|
| 4 |
I assume this Makefile to work with any non-GNU make: |
| 5 |
|
| 6 |
CFLAGS=`sdl-config --cflags` -Wall -Wextra |
| 7 |
LDFLAGS=`sdl-config --libs` |
| 8 |
OBJ=tron.o pixel.o |
| 9 |
|
| 10 |
.PHONY: clean run |
| 11 |
|
| 12 |
tron: $(OBJ) |
| 13 |
|
| 14 |
run: tron |
| 15 |
./tron |
| 16 |
|
| 17 |
clean: |
| 18 |
rm -f *.o tron |
| 19 |
|
| 20 |
Now how would we fix this to respect custom CFLAGS (and LDFLAGS) in a |
| 21 |
way that does not require GNU make (i.e. simply-expanded variables): |
| 22 |
|
| 23 |
"[Recursively-expanded variables are] the only sort supported |
| 24 |
by other versions of make". [1] |
| 25 |
|
| 26 |
Any proposals for a generic solution that is upstream-suitable? |
| 27 |
While the Makefile presented here is not likely to go into the tree I |
| 28 |
had similar cases before so I felt like bringing this up. Thanks! |
