building on MacOS #12

Closed markghayden closed 9 years ago

markghayden commented 9 years ago

I am building on up-to-date MacOS system. Trying to build 4.02.3 stop on the error below, apparently in building ocamldoc. Undoing part of the recent change to enable OCAMLDOC (in Makefile.in) seems to be a work-around.

best, Mark

There's nothing in your comment besides signature.

whitequark commented 9 years ago

In the log you sent me, the build system runs sh ./runocamldoc, but the patch removes all traces of that.

markghayden commented 9 years ago

To be honest, I don’t understand how the internals of this cross compilation environment with opam works. I didn’t make any changes that I’m aware of. I just ran the commands in the instructions. Are there some files I can provide that would explain this?

The full output of opam update android && opam install ocaml-android32 -v. The patch isn't being applied for some strange reason.

markghayden commented 9 years ago

I’m also seeing strange behavior with OCaml .a files, such as libasmrun.a and libunix.a. The files in the archive all seem to end in ‘/‘

Do you have access to a MacOS development machine? I could set up a login on one of ours.

Well, I certainly appreciate your help. I’ll switch back to my Linux host for doing Android builds for the time being. —M

The log above confirms my suspicion: the patch isn't being applied. I have no idea why; maybe ask on #opam on irc.freenode.net?

markghayden commented 9 years ago

I removed .opam/repo/android, synced and rebuilt from scratch, including 4.02.3+32bit. Got the same result.

I switched back to 64-bit debian and appear to be running into the same strict-aliasing problem there, with the same warning/error in md5.c for ocamldoc. Same work-around fixes it.

I guess there could be a bug in opam affecting debian and macos...

I’ve been using opam-android with 4.02.1 for some time (with great success) and was hoping to upgrade toolchain to 4.02.3.

It sounds like you are busy but if you want to see my SEAiq app running on Android, you can download a free copy here: http:/doc.seaiq.com/dist . Pilots are already using it on River Seine for commercial vessels… Thanks again for your help.

Oh, you're the SEAiq person! I remember, yes.

The problem is not with md5.c... that's just a warning. Look at the line in stderr which says "sh ./runocamldoc" and then promptly fails to execute the (wrong) camlrun binary. That's the actual culprit.

I'll take a look into it when I have time.

markghayden commented 9 years ago

Thanks for looking into this. With the minor change I mentioned, I did get 64-bit debian upgraded to 4.02.3 and it appears to be working fine.
