Comment 1 :aceman 2011-12-01 04:38:39 PST
What is your gcc version?
Comment 2 :aceman 2011-12-01 07:33:55 PST
Can you try adding the line
"#include <unistd.h>"
as the 14th line in that file? (before #include <fstream>)
Comment 3 George R. Goffe 2011-12-01 12:49:10 PST

I have two gcc compilers here and have tried both... Each gets the same failure.

Comment 4 George R. Goffe 2011-12-01 12:49:40 PST
I'm building with our suggested change now.


Comment 5 :aceman 2011-12-01 13:14:58 PST
Ok, comment if it builds and runs fine.

I wonder where that include disappeared, it seems it was already included in the past: commit .
Comment 6 George R. Goffe 2011-12-01 14:31:38 PST

I did see the include in the ifdef just before where you told me to insert that include... Maybe the ifdef is wrong?

By the way, I had autoconf-4.65 on this system which caused the build processes to fail with something called "defn" missing... 

These files have a mixture of m4_defn, m4_define, and defn. The "defn"s cause my build to fail until I downgraded my autoconf to 2.13. Is this a bug?



Comment 7 George R. Goffe 2011-12-01 14:38:40 PST

I tried both compilers with the same resulting failure. Way past your(?) code.

Now what?

Yes, only autoconf 2.13 are supported (yes, that is ancient but there are some reasons).

Is -fno-rtti compiler flag added by you? If yes, try to remove it.
You can also add 'ac_add_options --disable-crashreporter' into mozconfig, if you do not need it.
But this no longer the topic of this bug. Try to discuss this on with somebody.
Comment 11 Ed Morley (Away 28th Oct -> 6th Nov) [:emorley] 2011-12-12 17:43:30 PST
Please could you tweak your hgrc to automatically add author info (guide here: + add a commit message when attaching patches, since it makes pushing half a dozen checkin-neededs a lot easier. Thanks :-)
Comment 12 :aceman 2011-12-13 02:08:20 PST
Ok, I can try that. But you will still need to add the reviewers.
Comment 13 Ed Morley (Away 28th Oct -> 6th Nov) [:emorley] 2011-12-15 02:21:53 PST
Adding "; r=foo" takes a lot less time than constructing the user line / coming up with a commit message, so if you could do the latter, that would be a big help :-)
Comment 14 :aceman 2011-12-15 02:37:04 PST
Yes, I'll try to migrate to using the mq extension according to the page you linked. I'll try creating new patches with it.

But I have one question. Visitors not logged into bugzilla do not see email addresses of bug commenters. But I think they can see attachment contents. The patch will contain my email. I am not yet sure if it is a problem for me. But is this solved in any way?
Comment 15 Ed Morley (Away 28th Oct -> 6th Nov) [:emorley] 2011-12-15 02:41:00 PST
Once your patch lands, it will be public anyway, see:

As such, if you would rather keep your email address hidden (I can totally empathise, I have an aversion to spam myself), then I recommend setting up a bugzilla/mozilla only account and forwarding/fetching mail to your current email address.
Comment 16 :aceman 2011-12-15 02:51:01 PST
OK, thanks. I already have the separate address for bugzilla, I just wanted to protect it too, if possible.

Is it enough to put the bug number and summary as the user commit line? Do other people put something better there?
Comment 17 Ed Morley (Away 28th Oct -> 6th Nov) [:emorley] 2011-12-15 03:02:47 PST
The commit message is normally in the format:
Bug 123456 - What was changed; r=foo

ie: Making sure to explain what changed and not just what the problem was. (Bugzilla bug summaries are obviously often more about the latter).
Comment 18 :aceman 2011-12-15 12:54:06 PST
OK, can you see if my patch in bug 652555 meets these criteria?
Comment 19 Ed Morley (Away 28th Oct -> 6th Nov) [:emorley] 2011-12-15 15:22:55 PST
Patch commit message in bug 652555 looks fine to me :-)
Comment 20 :aceman 2011-12-16 00:27:36 PST
Thanks. So what about the patch here? Will you merge it, or do you wait for me to update it?
