meh, an old project of mine uses Batteries.Rope. is there a replacement?

or do I choose to become contaminated by lgpl when I copy the implementation from old Batteries :P

Does anyone honestly read the forge bug tracker. There are exactly three bugs listed, all submitted in 2011 when the project was first moved to the forge. No bugs reported since, apparently.
<adrien_oww>
API in lablgtk is only added when someones uses it
<adrien_oww>
or you can have bug creep with noone seeing bugs for years
<adrien_oww>
people didn't get notifications from the forge at first but now it sends mails so you have good chance with that

All right, thanks, I'll send a patch to the list.

Hello, does anyone know what I'm doing wrong when I get an error "Error : hd" without any stacktrace? Usually on errors I get a nice stacktrace of everything.
<adrien_oww>
probably raised by List.hd
<adrien_oww>
empty list probably
<Simn>
Yes, I know, but I don't know where it comes from.
<|jbrown|>
try the debugger?
<Simn>
That's certainly an option, although the usual stacktrace would do for now.
<|jbrown|>
dunno, you could try fiddling with OCAMLRUNPARAM

I'm doing both. As I said I get nice stacktraces on other errors, which is why I find this confusing. I'm on 3.11 by the way.

The debugger is fun, but OCaml code nearly never has a bug; it's always the C libraries :/

We don't catch that specific error. Do I have to do something special for standard modules like list.ml to respect -g?
hkBst__ has quit [Read error: Connection reset by peer]
<|jbrown|>
is the error you pasted literally exactly what you get? Because I get 'Fatal error: exception Failure("hd")' for List.hd on an empty list.
<|jbrown|>
...and a backtrace
<|jbrown|>
that's with 3.12.1
johnthetubaguy has joined #ocaml

<Simn>
Yes, it's just plain "Error : hd".
<adrien_oww>
actually "Error : hd", written like that is not from the stdlib
<adrien_oww>
any libs?
<|jbrown|>
that's why I thought you might be catching the exception somewhere and handling it in some way.
<adrien_oww>
especially ones written by french people :-)
<|jbrown|>
so -- if you're using some random 3rd-party lib, I'd point the blame there :-)
<Simn>
Let me investigate in that direction. :)
<invariant>
adrien_oww, yeah, I hear they only work 3 hours/day.

I'll agree that if you want to code, there are better keymaps, I don't see the problem with writting english however

I'm having a bit of trouble installing any version of ocaml with opam on Ubuntu 12.10. Despite the fact that I am running on a 64 bit system (uname -r returns 3.7.5-x86_64) the configure phase of `opam switch 4.00.1` begins with something like "OK, this is a regular 32 bit architecture"
<pygmalion>
Then the whole thing bombs out with "invalid instruction suffix" errors for mul, add, sub, div, etc.
<thelema>
pygmalion: interesting. Can you try ocamlbrew?
<pygmalion>
I hadn't thought to check the gcc version.
<pygmalion>
So it is indeed a 32 bit executable, which I guess wouldn't matter if you passed -m64 with CFLAGS. I guess I will try to force an upgrade of it.

that's mine; you've got a 386 version of gcc installed; maybe remove it and pick the amd64 version from aptitude?

thelema: this seems like a more complicated problem than originally thought. uname and the arch command both suggest I'm running a 64-bit OS (and kernel) but `file /sbin/init` is a 32 bit executable. Clearly, none of this is an ocaml issue so I'll start digging in and try to figure out how I did this to myself!

thomasga: is it sufficient to modify the opass.0.2.1 entry to specify 108.08.00 versions for core and core_extended? Do I need to bump the version modify 0.2.1?
<thomasga>
yup you can just change the constraints of the current package, no need to add a new tag
<thomasga>
let me check the package
<orbitz>
right now it just wants core and core_extended
<orbitz>
thomasga: also, do you know why avsm is getting 108.07.01 there? On my own machine it requiets 108.08.00

I guess 108.08.00 is not available for ocaml 3.12.1

ah ok

so does your package works with recent versions of core or with older ?
