Oh.

Well, I guess the next thing is for you to show us test.gpr and
librdf.gpr.

This could have gone quicker if you'd done that in the first place.

Please, try to put yourself in our shoes. How could you possibly help us
if we asked you that question with just that information?


Actually, I think there *is* an error in gnatmake/gprbuild: maybe that
should have been RUNTIME and MODE.

I wrote this in a GPR

   type Var_Type is ("foo", "bar");
   Var : Var_Type := external ("VAR");

and then

   $ gprbuild -P test2 -Xvar=foo
   test2.gpr:19:04: no value defined for "var"
   test2.gpr:19:24: warning: undefined external reference

whereas

   $ gprbuild -P test2 -XVAR=foo

works fine. So the error message is confusing; the undefined symbol is
shown in lower case, disregarding the actual case required.

I've reported this to AdaCore.
