I’m trying to create binaries for the [fastcluster](http://github.com/jmboehm/Fastcluster) library, which I would like to then wrap with a [wrapper that I’ve written](http://github.com/jmboehm/Fastcluster.jl). Unfortunately, I cannot get the wizard to find the shared library that’s the output from `make` and `make install` (but it’s there, really, and I can `ccall()` it on my OSX and Windows machines): I keep getting “The build has produced no binary artifacts”. I’ve tried using a manually written Makefile (the build is really trivial), and using autoconf, always with the same outcome. What am I doing wrong?

My makefile is this:

```julia
CC=gcc
CFLAGS=-I.
LDFLAGS = -lm

libfastcluster.so: fastcluster.o
	$(CC) -shared -fPIC -o libfastcluster.so fastcluster.o -lstdc++ $(LDFLAGS)

fastcluster.o: src/fastcluster.cpp
	$(CC) -fPIC -c src/fastcluster.cpp -o fastcluster.o

.PHONY: install
install:
	mkdir -p lib
	mv libfastcluster.so lib/libfastcluster.so

.PHONY: clean
clean:
	rm -f fastcluster.o

```

and the build process is just `make` and `make install`, or, when using autoconf, the standard `configure` before that.

I’ve noticed [https://github.com/JuliaPackaging/BinaryBuilder.jl/issues/200](https://github.com/JuliaPackaging/BinaryBuilder.jl/issues/200), but believe that this is different since it happens also when I install the output library in the `/bin` subfolder.

Thanks for any help.

The artifacts are expected to be in the `$prefix` directory. The `install` rule should copy the files there.

Thank you, that was exactly the piece of information that I was missing.
