Thanks for the report! It looks like a few things changed in ocaml bindings since the rc where I tested with USE=ocaml :/ Adding dev-ml/ounit and dev-ml/findlib to dependencies is easy, but I can not find ctypes, is it this one? https://github.com/ocamllabs/ocaml-ctypes/releases Cc'ing ml folks for opinion on this potentially new package to add in tree
added dev-ml/ocaml-ctypes-0.4.0 ; please test
(In reply to Alexis Ballier from comment #6) > added dev-ml/ocaml-ctypes-0.4.0 ; please test configure ran to the end, thanks for the speedy add!I did not have time to check the entire compilation process though Also, I have not committed the new deps yet, as they will require some ppc/arm keywording For those that want to test in the meantime, the packages to add: dev-ml/findlib dev-ml/ocaml-ctypes dev-ml/ounit
Hey all, thanks for the quick reaction and the ebuild. I emerged dev-ml/ocaml-ctypes and dev-ml/ounit (findlib was already installed) and retried. While the configuration phase shows no problems, the compilation fails at a later stage.
Created attachment 399052 [details] build.log if ocaml-ctypes is installed (xz compressed) relevant part: File "/var/tmp/portage/sys-devel/llvm-3.6.0/work/llvm-3.6.0.src-abi_x86_64.amd64/bindings/ocaml/executionengine/Release/llvm_executionengine.ml", line 54, characters 28-77: Error: This expression has type nativeint but an expression was expected of type int64
As stated at http://llvm.org/releases/3.6.0/docs/ReleaseNotes.html it needs OCaml >=4.00.0, ocamlfind, ctypes >=0.3.0 <0.4 and OUnit 2, so it seems to me that ctypes 0.4 release is too fresh for it.
I am trying to build it with ctypes v. 0.3.4 now.
It built and installed fine with =dev-ml/ocaml-ctypes-0.3.4.

Indeed, this is probably caused by: * Use nativeint to represent pointers in https://github.com/ocamllabs/ocaml-ctypes/blob/master/CHANGES.md This looks cleaner, I have a one-liner patch that seems to fix this. Testing compilation, then I'll add it here

I hit the error at the next system.

(In reply to Juergen Rose from comment #23) > @Bernard Cafarelli > > Can these patches not add to default portage tree? The patch is already applied in 3.6.1 :) So for now you just need to install the mising deps as listed in comment #17 (findlib, ocaml-ctypes, and optionnaly ounit) I can not add these dependencies in the ebuild yet, as they lack some keywords (that's blocker bug #543604)
Now I get the same error with llvm-3.6.2.
I masked the USE-flag on missing arches (sparc and powerpc), so I could finally add the dependencies, thanks everyone!
