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
