Re: [Libguestfs] [PATCH] Don't rely on OCaml native compiler for tests

* Török Edwin: This works for me. Great, thank you! "make check", at least when it is called from within the ocaml subdirectory, just sets LD_LIBRARY_PATH. Which comes pretty close to what libtool would do, I suppose. This seems to be defined by setting TESTS_ENVIRONMENT. BTW, can someone tell me what the meaning of $(VG) right there? Since the test programs are already listed, I have replaced the individual "t/hivex_*_*" lines with this: ,---- | t/%: t/%.cmo mlhivex.cma | $(LIBTOOL) --mode=execute -dlopen $(top_builddir)/lib/libhivex.la \ | $(OCAMLFIND) ocamlc -dllpath $(abs_builddir) -package unix -linkpkg \ | mlhivex.cma $< -o $@ `---- And it still builds and the tests run fine, at least on my amd64 Debian/unstable workstation. Running the failing command under ltrace reveals that ocamlc uses dlopen() to open dllmlhivex.so which is referenced by mlhivex.cma. Then it uses dlsym(), apparently in order to verify that some symbols can be resolved. This fails if libhivex.so.0 cannot be found, because dllmlhivex.so depends on it. Ah well, it seems I just got some steps closer to understanding how autofoo and the OCaml toolchain operate. Cheers, -Hilko
