Build QT 5.2.0 on FreeBSD from source

? This user is from outside of this forum

I did it. But not succesfully – xcb don’t compiling.

Because someone hardcoded -ldl in xcb's project file. Remove it.
-ldl is never supposed to be hardcoded in project files, it is supposed
to be dragged in by the Qmake specs on those platforms that really
need this library. (There are also platforms where it is named -ldld).

I don’t know how to solve this ((

Using that "timezone" variable is a crock anyway. The correct way
were to use tm_gmtoff from struct tm:

```
   time_t dummy = (time_t)0;
```
```
   struct tm *p = localtime(&dummy);
```

   return -p->tm_gmtoff;   // tm_gmtoff uses positive values east

                           // of UTC, but historic "timezone"

                           // variable used positive values west

```
                           // of UTC.
```

#else
return timezone;
#endif // Q_OS_WIN

I also needed an #include <sys/utsname> in order to use
uname(3) correctly:

Still, I didn't succeed completely. My current stop is here:

@
/usr/local/qt5/src/qt-everywhere-opensource-src-5.2.0/qtbase/lib/libQt5PlatformSupport.a(qevdevmousemanager.o): In function QEvdevMouseManager::QEvdevMouseManager(QString const&, QString const&, QObject*)': /usr/local/qt5/src/qt-everywhere-opensource-src-5.2.0/qtbase/src/platformsupport/input/evdevmouse/qevdevmousemanager.cpp:94: undefined reference to QDeviceDiscovery::create(QFlagsQDeviceDiscovery::QDeviceType, QObject*)'
@

(Replace the "(at)" strings in the patches by "at" signs. There
doesn't appear to be a way to have those signs as part of a code
block here.)

(I dropped my previous account, as my original one has been recovered now.)

The QDeviceDiscovery stuff requires this patch:

Next, there's couple of instances where Linux' pthread_getattr_np()
needs to be replaced by FreeBSD's pthread_attr_get_np():

Then, there's alloca(), but apparently only ever tested on
Linux. FreeBSD doesn't have alloca.h but declares it in stdlib.h.

Finally, all the multimedia stuff appears to be written for Linux only.
There's plenty of #include <linux/something> all over the place. :(
In order to get it compile at least (it won't make sense at runtime), I
needed these patches:

With all that, I got it to compile. Alas, 1 GB of my datasegment size is too
small to link it. :-( I'm afraid I have to reboot now ...

Will certainly do, but I'd like to get it working for me, first.

By posting it here, I was in hope to catch the attraction of some
other FreeBSD developers before ...

SGaist

A central place to retrieve your patch would be a good idea then. Fellow developers could then jump in to help

I'll review the patch before, and upload it onto my web server.

But now it's close to midnight here, time to fall asleep.
