Hi,
I tried to do code coverage testing for libguestfs with gcov.
The steps are shown as follows:
1. Download and install the source package(libguestfs-1.36.5-1.el7.src.rpm)
2. Modify libguestfs.spec file
#diff -u libguestfs.spec libguestfs.spec.modify

The patch in attachment added in libguestfs.spec aims to resolve the above issue. But it
seems to have no effect. Any idea how to resolve this issue? Thanks.

I suppose that we need to link the OCaml bindings to -lgnu, which
your patch attempts:
+libguestfsocaml_a_LIBADD = \

... but the problem is that libguestfsocaml.a isn't really used for
anything. See the comment in the same Makefile.am:

# library; we link with the object files that it generates.
noinst_LIBRARIES = libguestfsocaml.a
You'll need to change all the places where
$(libguestfsocaml_a_OBJECTS) is used instead, eg something like this
untested change:
stamp-mlguestfs: libguestfsocaml.a $(guestfs_cmm)
$(OCAMLMKLIB) -o mlguestfs \
$(libguestfsocaml_a_OBJECTS) guestfs.cmo \

I will read it later. And I need to think about how to do code coverage in this way.
Thanks.

The problem is unrelated to the patch.
$(LDFLAGS) are added to the ocamlmklib command, but ocamlmklib only
understands a limited subset of linker flags, including -L but not
including -Wl.
Possibly something like this might work:
stamp-mlguestfs: libguestfsocaml.a $(guestfs_cmm)
$(OCAMLMKLIB) -o mlguestfs \
$(libguestfsocaml_a_OBJECTS) guestfs.cmo \
- $(LDFLAGS) \

$(LTLIBINTL) \
-L../lib/.libs -lguestfs
(in all the places where $(LDFLAGS) is passed to ocamlmklib).
