Need test binaries with shared libraries

Hi Baptiste,

please consider running under MacOS in an empty directory

all: clean macosfat.bin

LIPO?=lipo
TARGET_ARM=arm64-apple-macos10.13
TARGET_AMD=x86_64-apple-macos10.13

clean:
	rm -f answer.c main.c
	rm -f *dylib*
	rm -f bin-*
	rm -f *.bin

answer.c:
	echo 'int answer() { return 42;}' >$@

main.c:
	echo 'int answer(); int main(const int argc, const char *argv[]) { return answer(); }' >$@

libAnswer.A.dylib-aarch64: answer.c
	$(CC) -target $(TARGET_ARM) -dynamiclib -install_name /usr/local/lib/libAnswer.A.dylib $< -current_version 1.1 -compatibility_version 1.0 -o $@

libAnswer.A.dylib-amd64: answer.c
	$(CC) -target $(TARGET_AMD) -dynamiclib -install_name /usr/local/lib/libAnswer.A.dylib $< -current_version 1.2 -compatibility_version 1.0.1 -o $@

%.bin:
	$(LIPO) -create -output $@ $^

macosfatlib.bin: libAnswer.A.dylib-aarch64 libAnswer.A.dylib-amd64

bin-aarch64: main.c macosfatlib.bin
	$(CC) -target $(TARGET_ARM) $^ -o $@ 

bin-amd64: main.c macosfatlib.bin
	$(CC) -target $(TARGET_AMD) $^ -o $@  

macosfat.bin: bin-aarch64 bin-amd64

And replace macosfat.binin with the generated file and adding macosfatlib.binin with the generated library.

These (still trivial) binaries are needed to write unit tests against pkg_abi_macho with shlibs_required/shlibs_provides.
@ifreund
I suggest to have similar binaries for the other major platforms.

Cheers,
K

I can do that as I don't have any access to any macos @emaste would it be possible for you to do that and host it on freefall so I can fetch it?

I have put the files temporarily into my draft PR, but I do prefer that they are built from within a trusted environment.
Btw. you have access to MacOS via GitHub. It would be trivial to build most of the binaries there. You could have a branch with the scripts and a GH action to build them. Both MacOS as well as Ubuntu runners can also cross-build to FreeBSD possibily also to DragonFly BSD.

added, we will see to cross build everything later
