The Makefile doesn't work

[angelog0]

It works in

make
make all

but fails in building the examples as in:

$ make window
make: ***  Nessuna regola per generare l'obiettivo "examples//.f90", necessario per "window".  Arresto.

(It means: No rule to generate the target "examples//.f90", needed for "window". Stopping.)

Are we sure that using $* here

$(WINDOW): $(DIR)/$*/$*.f90 $(SDL_OBJ)

is the right thing?

At the end, I applied this workaround:

All examples build and run but most crash (on exit, when one clicks the X to close the window: strangely this occurs only on GNU/Linux not on MSYS2/MINGW64) with:

It seems that only window and bounce do not crash.

[interkosmos]

It seems you are using GNU make. But the Makefile is written for BSD make. After you have installed BSD make, run bmake.

@interkosmos, I would suggest you make the Makefile compliant with GNU make. Maybe BSD make is on macOS but other *nix systems have GNU make by default...

[interkosmos]

It depends on the point of view: on BSD derivates one has to install GNU make (gmake), on Linux one has to install BSD make (bmake). Probably, you are right. I have not much experience with GNU make, but try to migrate to it in future.
