WARNING: This crude recipe by an absolute D newbie has not yet been tested--corrections are welcome!
Assume one has the following, error-free files:
- a D language source program:
- ./main.d
- a C ABI library file:
- /usr/local/lib/libbu.so
- a D language binding file to the C library API headers:
- /usr/local/include/bu.d
We first create a GNU Makefile to build program test-bu using those three files (note the leading spaces on lines following targets must be tabs in a real GNU Makefile):
$ cat Makefile
# use the dmd compiler
DMD = /usr/bin/dmd
LIBDIR = /usr/local/brlcad/lib
MODDIR = /usr/local/brlcad/include
BINDING = $(MODDIR)/bu.d
all: test-bu
test-bu: main.o bu.o
$(DMD) -o $@ main.o bu.o -L$(LIBDIR) -lbu
%.o: %.d
$(DMD) -c $< -o $@
bu.o: #(BINDING)
$(DMD) -c $< -o $@
clean:
-rm *.o
Then we can build test-bu by executing:
$ make test-bu
The GNU Makefile can be made more general and efficient, but it should produce the desired binary program.
