+This test checks that if a library is declared with `(no_dynlink)`, then the
+corresponding `.cmxs` file is *not* built.
+
+  $ cat >dune-project <<EOF
+  > (lang dune 3.17)
+  > EOF
+
+First we check the behaviour when `(no_dynlink)` is not present.

+  $ cat >dune <<EOF
+  > (library
+  >  (name mylib))
+  > EOF
+
+  $ touch a.ml
+
+  $ dune build _build/default/mylib.cmxs
+
+Now with `(no_dynlink)`.

+  $ cat >dune <<EOF

+  Error: Don't know how to build _build/default/mylib.cmxs
+  Hint: did you mean _build/default/mylib.cma or _build/default/mylib.cmxa?
+  [1]
+
+Next, we check that the .cmxs is installed without `(no_dynlink)`:
+
+  $ cat >dune-project <<EOF
+  > (lang dune 3.17)
+  > (package (name mylib))
+  > EOF
+
+  $ cat >dune <<EOF
+  > (library
+  >  (public_name mylib))

+
+  $ dune build _build/default/mylib.install
+
+  $ grep cmxs _build/default/mylib.install
+    "_build/install/default/lib/mylib/mylib.cmxs"
+
+And *not* installed with `(no_dynlink)`:
+
+  $ cat >dune <<EOF
+  > (library
+  >  (public_name mylib)
+  >  (no_dynlink))
+  > EOF
+
+  $ dune build _build/default/mylib.install
