+Date: Tue, 21 Mar 2023 01:54:04 -0300
+Subject: [PATCH] Fixing make check and make distcheck
+
+  Notes: the main goal of this patch is to remove the hard coded
+  libguile-cairo path, which makes it impossible to run 'make check',
+  unless you actualy first install the version you are working
+  on/checking [which is 'none sense'].
+
+  Also, even with the above problem fixed, there were still a few
+  nitpick things to solve so that make distcheck pass.
+
+  Finally, while workig on this patch, I also made a few cosmetic
+  changes, mostly adding a space before and after '=' in Makefile.am
+  targets, as well as having each filename on its own line for targets
+  that requires filenames. Those changes are not commented here below.
+
+* Makefile.am: (1) removing the env target, as we update env.in
+  this is not only not necessary anymore, but would actually
+  raise an error; (2) the CLEANFILES target misses $(GOBJECTS);
+  (3) using $(AM_V_GEN) in .scm.go target; (4) the EXTRA_DIST
+  target misses $(SOURCES), and does not need to ship autogen.sh
+  nor build-aux/git-version-gen.
+
+* cairo.scm: Call (dynamic-link "libguile-cairo"),
+  not (dynamic-link *cairo-lib-path*).
+
+* cairo/Makefile.am: (1) using $(AM_V_GEN) in .scm.go target; (2) in the
+  config.scm target, removing the @cairolibpath@ substitution; (3) the
+  EXTRA_DIST target misses vector-types.scm and $(NOCOMP_SOURCES).
+
+* cairo/config.scm.in: Removing the *cairo-lib-path* definition.
+
+* env.in: (1) define and use abs_top_srcdir and abs_top_builddir; (2)
+  define and export GUILE_LOAD_PATH, GUILE_LOAD_COMPILED_PATH and
+  LTDL_LIBRARY_PATH.
+
+* tests/unit-tests/Makefile.am: (1) add context-pointer.scm to the TESTS
+  target; (2) add a TEST_EXTENSIONS = .scm target; (3) update the
+  TESTS_ENVIRONMENT to use $(abs_top_builddir); (4) remove the %.check
+  target (unecessary in 'modern' autotools).
