building qt 4.7 beta2 fails with
...
"./wtf/MathExtras.h", line 194: Error: isfinite is not a member of std.
"./wtf/MathExtras.h", line 195: Error: isinf is not a member of std.
"./wtf/MathExtras.h", line 196: Error: isnan is not a member of std.
"./wtf/MathExtras.h", line 197: Error: signbit is not a member of std.

the attached patch fixes that by adding Solaris to the ifdef already provided for MSVC and Android


this is on OpenSolaris b134 using the Sun Studio 12u1 compiler

I can confirm this bug.

Please apply Pavel's patch! It's working fine.

Actually I think that the code in trunk should also work:

#if !COMPILER(MSVC) && !COMPILER(WINSCW) && !(COMPILER(RVCT) && (OS(SYMBIAN) || PLATFORM(BREWMP)))

Here's how it was before and what is still being used in Qt 4.7:

#if !COMPILER(MSVC) && !COMPILER(RVCT) && !OS(ANDROID) && !COMPILER(WINSCW)

I'll tell the Nokia guys to update their webkit...


Looks like this bug can be closed. Pavel, do you agree?

it certainly does not look like anybody from webkit cares about buildability on solaris, so for me it does not make any sense to spend time on development versions. I'll tell when the next Qt version is out.

For the record, we gladly accept build fixes, but please don't disregard <http://webkit.org/coding/contributing.html>.

In particular, patches that are not marked r? likely won't be noticed, and patches without ChangeLogs will be not accepted.

We don't have a buildbot for solaris but it is certainly supported. We accept patches for sure.

The problem here is that nobody saw you patch until now. I just learned about it because a colleague triaged this http://bugreports.qt.nokia.com/browse/QTBUG-16448

There are two problems in this bug report that made it invisible for us:

First, you have not used the template to report this bug. Since the keyword "Qt" is missing, this bug was never triaged by us. See http://trac.webkit.org/wiki/QtWebKitBugs for more info.

Second, your patch was missing the changelog and was not marked for review. Such a patch does not appear in the review list. See http://trac.webkit.org/wiki/QtWebKitContrib for more info.

Finally, if a patch is ignored, you can always write on the WebKit mailing list (webkit-qt and webkit). We welcome contribution, you were just unlucky and nobody from Qt saw the bug.

Closing the bug then.

Reopen this bug.  The #if line from comment #2 fails to compile on Solaris 10 with Sun Studio 12, and add "&& !OS(SOLARIS)" fixes the problem.

I will submit a new patch

The comment in #2 surely doesn't fix the issue on Solaris 10/Sun Studio 12 CC, as compiled with the qt-4.7.2.
Adding the patch completed the compile.

Pierre does that make sense to you?

The change looks good to me but I would like a confirmation that the STL is always broken on Solaris. What about the GNU tools on Solaris?

Yup, that looks good to me to, my general rule of thumb when it comes to dealing with Solaris is to really lower your expectations, that's what this patch does, so definitely thumbs up ! :)

Look sane and Pierre says ok.

All reviewed patches have been landed.  Closing bug.

I believe this latest patch is inappropriate for solaris if GCC is being used.

Perhaps it could better be done by changing:

&& !OS(SOLARIS) 

to 

&& !( OS(SOLARIS) && defined(__SUNPRO_CC) )

or something of this nature.

Please open a new patch and upload a new bug.  We have very very few solaris users, so if you don't fix it, no one will. :)
