This makes the "make -C src cov" rule work with the addition of the libvirt_test.la convenience library. The trouble is that since there are now two .o files per .c (one for the "real" libvirt library, and another for the convenience library, libvirt_test.la, with no access restrictions, for testing), when you generate test-coverage stats, you have stats for each .c file in two different places, one for each .o file. This solves the problem by running gcov on each pair of .o files. A minor twist: when profiling with --disable-shared, the .o files are in ".", rather than in ".libs/", so configure.in now records the dirname in a new AC_SUBST'd variable, LV_LIBTOOL_OBJDIR, and src/Makefile.am uses that. Thus, profiling works with shared as well as static libraries. Rewrite test-coverage rules to accommodate multiple .o files per .c. * src/Makefile.am (cov): Rewrite rule to merge gcov results corresponding to two .o files: the libvirt_la- one, and the libvirt_test_la- one. (tst): Remove unused rule. * configure.in (LV_LIBTOOL_OBJDIR): Define and AC_SUBST.
