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.

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.

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 opam-version: "1" version: "4.03.0" src: "https://github.com/ocaml/ocaml/archive/4.03.0.tar.gz" build: [ [ "git" "clone" "https://github.com/alainfrisch/flexdll.git" ] [ "cp" "flexdll/flexdll.h" "/usr/x86_64-w64-mingw32/sys-root/mingw/include" ] [ "cp" "config/m-nt.h" "config/m.h" ] [ "cp" "config/s-nt.h" "config/s.h" ] [ "cp" "config/Makefile.mingw64" "config/Makefile" ] [ make "-f" "Makefile.nt" "PREFIX="prefix "flexdll" ] [ make "-f" "Makefile.nt" "PREFIX="prefix "world" ] [ make "-f" "Makefile.nt" "PREFIX="prefix "opt" ] [ make "-f" "Makefile.nt" "PREFIX="prefix "opt.opt" ] [ make "-f" "Makefile.nt" "PREFIX="prefix "install" ] ] Intel Deutschland GmbH Registered Address: Am Campeon 10-12, 85579 Neubiberg, Germany Tel: +49 89 99 8853-0, www.intel.de Managing Directors: Christin Eisenschmid, Christian Lamprechter Chairperson of the Supervisory Board: Nicole Lau Registered Office: Munich Commercial Register: Amtsgericht Muenchen HRB 186928 [-- Attachment #2: Type: text/html, Size: 7941 bytes --] ^ permalink raw reply [flat|nested] 6+ messages in thread
