Unable to install android cross-build tools #2226

Closed nobrowser closed 7 years ago

nobrowser commented 9 years ago

I am trying to follow the instructions here:

https://github.com/whitequark/opam-android/blob/master/README.md

My build system is amd64 with Debian wheezy. I follow the instructions exactly, but:

eval `opam config env`
 [2+0]~$ eval `opam config env`
 [3+0]~$ ANDROID_LEVEL=21 ANDROID_ARCH=armv7 opam install ocaml-android
Your request can't be satisfied:
  - No package matches ocaml-android.

No solution found, exiting

Strangely,

 [5+0]~$ opam list -a | fgrep ocaml-android
ocaml-android               --  A meta-package depending on any OCaml cross-comp
ocaml-android32             --  OCaml cross-compiler for 32-bit Android targets

which version of OPAM do you have installed? Is it 1.2.0+?

Built from git source at the 1.2 tag

(note: you can use opam list '*ocaml-android*', or opam search, rather than grep)

It's weird because the error you get is an error from the solver, that normally happens when you specify unsatisfiable version constraints. Opam would have failed earlier if no package by this name existed. Care to include opam config report ?

nobrowser commented 9 years ago

I have

OPAMUSEINTERNALSOLVER=1

would that make a difference?

AltGr commented 9 years ago

Yes, please try with the external solver (e.g. aspcud). config report ?

@nobrowser Your problem is that you're trying to use a 32-bit compiler on a 64-bit switch. This won't work; do opam switch 4.02.3+32bit first.
