[forge] octclip & octproj build loop

[Marco Atzeri]

I was trying to build & package on cygwin these two old (2012) packages
but they produce a build loop (a build plus clean loop, I assume)
with hundreds on mkoctfile process explosion.

I presume that calling "compile and clean" is confusing a bit my Make


.PHONY: all
all: compile clean

.PHONY: compile
compile:
        $(CC) -c -v projwrap.c -o projwrap.o
        $(CC) -s -v _op_transform.cc projwrap.o $(LDFLAGS)
        $(CC) -s _op_fwd.cc projwrap.o $(LDFLAGS)
        $(CC) -s _op_inv.cc projwrap.o $(LDFLAGS)
        $(CC) -s _op_geod2geoc.cc $(LDFLAGS)
        $(CC) -s _op_geoc2geod.cc $(LDFLAGS)

.PHONY: clean
clean:
        rm -rf *.o



$ make --version
GNU Make 4.1

Can someone confirm it on other systems before I open a
bug and prepare the patches ?
I assume is not a make bug.
