Looks like a missing dependency… though I have no idea how it slipped in. I’ll take a closer look at it this afternoon.

For some reason I get this strange error:
==> Starting build()...
ocamlfind: Package `result' not found
W: Field 'pkg_result' is not set: Command ''/usr/bin/ocamlfind' query -format %d result > '/tmp/oasis-ff9362.txt'' terminated with error code 2
E: Cannot find findlib package result
E: Failure("1 configuration error")
==> ERROR: A failure occurred in build().
==> ERROR: Makepkg was unable to build ocaml-lwt.

Any ideas?

I added it to the configure line. Thanks for the notice!

I think this package should now be compiled with --enable-camlp4 too (needed since 2.4.4). See:

cormac-obrien commented on 2014-11-12 22:22

Not 100% sure, but this package appears to be out of date.

E: Cannot find findlib package camlp4
E: Cannot find findlib package camlp4.extend
E: Cannot find findlib package camlp4.quotations.o
E: Failure("3 configuration errors")
==> ERROR: A failure occurred in build().

I have ocaml-findlib and camlp4 installed from the official repos.

Lwt 2.4.4 (and 2.4.5) have now been released, which should fix these problems:

bcdarwin commented on 2014-02-02 04:55

Ocaml-lwt < 2.4.4 won't build with ocaml >= 4.01, so this package should add 'ocaml <= 4.00' to `depends`. This will be resolved when 2.4.4 is released.

In the meantime, I've released an ocaml-lwt-git package providing ocaml-lwt.

Build fails on my machine:

Thanks, fixed.
Updated to 2.4.2 as well.

2.4.1-1 needs a little fix with Ocaml 4.00.0:

Updated :)

zorun commented on 2011-09-18 17:18

The compiler libraries are now available as the "ocaml-compiler-libs" package in [extra].

Could you update the dependencies to reflect the change? Thank you!

Anonymous comment on 2011-09-16 20:31

Updated PKGBUILD -- *all* lwt features are now installed by default.

zorun commented on 2011-08-26 18:25

Actually, it depends on some ocaml internal libs, usually provided by an `ocaml-compiler-libs` package (although such a dependency is not stated in the README...) because toplevel-related stuff are internal to the ocaml compiler.

It would be alot easier if these libs were integrated in the `ocaml` package, see

Anonymous comment on 2011-08-26 17:49

I wonder how lwt folks build it, since that Types module is clearly missing <_<

zorun commented on 2011-08-26 02:47

Ok, as a quick hack, it compiles fine without `--enable-toplevel`... And ocaml-utop seems happy anyway.

Here is an updated PKGBUILD:

zorun commented on 2011-08-25 14:30

@superbobry: with your updated PKGBUILD (which is needed for `ocaml-lambda-term`), Lwt doesn't compile anymore. It starts well, but after a moment it fails:

Please note that it is *not* the same error as the one you would get by not installing react.o from `ocaml-react`.

Since nothing has changed since one week ago, I see multiple reasons for it to fail:
* an error in the PKGBUILD you've pasted (but I see nothing wrong);
* the recent modification of "CFLAGS", "CXXFLAGS" and "LDFLAGS" in /etc/makepkg.conf might have broken something;
* the error ("Error: Unbound module Types") suggests that there might be a missing dependency;
* I've got a lot of warnings about `/usr/lib/ocaml/site-lib` not existing; this is weird, I've never seen that before.

I'll try to investigate, but I don't quite see what's wrong...

Why won't you enable *at least* React helpers and enhanced toplevel -- the package depends on ocaml-react anyway?
