Dear OCaml Users,
Opam works fine for me with the system installed OCaml, but after an opam switch I cannot build ocamlbuild or any package depending on it any more.
Building ocamlbuild fails because it explicitly checks if there is already a system installed ocamlbuild:
# ERROR: Preinstalled ocamlbuild detected at /usr/local/lib/ocaml/ocamlbuild
# Installation aborted; if you want to bypass this safety check, pass CHECK_IF_PREINSTALLED=false to make
# make: *** [Makefile:333: check-if-preinstalled] Error 2
Of cause I can just follow this advice and remove this check, but I wonder how others handle this.
Best regards,
Michael

This is a bug, but I think it is likely to be coming from a
misconfiguration on your end: the preinstalled test checks
$(ocamlc -where)/ocamlbuild
and if you are in a non-system switch this should not be
/usr/local/lib/ocaml.
Did you correctly run
eval $(opam config en)
after switching?

Dear Gabriel,

I tried both (in a fresh shell). The effect is the same.
A question for my understanding: I assumed that for building something inside of opam this is not required. I thought I need to do this only when I use ocaml to build something outside of opam. This also matches my (very limited) experience with opam.
I try to find out what is going wrong here.
Best regards,
Michael

Feel free to open an issue on

Dear Gabriel,
with your pointers I found it.
I tried two things, one is to switch to a mingw64 4.03.0 compiler package I made myself. In this, as it looks, I messed up the transfer of the prefix to make (see my compiler file below), which results in the issues with building ocamlbuild.
Then I tried, as a cross check, a switch to the original opam 4.03.0 package and building ocamlbuild there. This also fails, but cause of a different reason (mantis #7268). Somehow I mixed things up in scrolling up my shell and thought it was the same bug.
The .comp file I experimented with is copied below. I didn’t yet find the right syntax to combine a string and a variable into one argument ("PREFIX="prefix), need to read the opam manual …
Best regards,
Michael

The opam variables `foo` is accessed as %{foo}% in opam metadata, so you
should use
"PREFIX=%{prefix}%"
