"Warnings" with NMake and MSVC2008

[vbman213]

Is it normal to see a few "Warnings" when building Qt with MSVC2008?

Do "warnings" mean that that particular piece of Qt failed to build? Or can I ignore them?


"Unreferenced Formal Parameter"

You can ignore them. They occur because of something like that:

void MyClass::someFunction(int parameter, bool isItTrue)
{
  // I do fancy stuff here, but I don't use parameter or isItTrue
}

void MyClass::someFunction(int parameter, bool isItTrue)
{
  // I do fancy stuff here, but I don't use parameter or isItTrue
}

To copy to clipboard, switch view to plain text mode 

because you don't use the parameters the compiler isforms you. To avoid the Warning you can use:

void MyClass::someFunction(int parameter, bool isItTrue)
{
  Q_UNUSED(parameter)
  Q_UNUSED(isItTrue)
  // I do fancy stuff here
}

void MyClass::someFunction(int parameter, bool isItTrue)
{
  Q_UNUSED(parameter)
  Q_UNUSED(isItTrue)
  // I do fancy stuff here
}

To copy to clipboard, switch view to plain text mode 

or

void MyClass::someFunction(int /*parameter*/, bool /*isItTrue*/)
{
  // I do fancy stuff here
}

void MyClass::someFunction(int /*parameter*/, bool /*isItTrue*/)
{
  // I do fancy stuff here
}

Hey,

sorry I haven't read your post carefully. I thought you are building your own project.
As for your last posted error there are some notes that intel has problems to build Qt: http://doc.trolltech.com/4.6/known-issues.html. One solution could be to turn off inlining for the compiler. But on that topic I am out...

I'm not using the Intel Compiler... I'm using MSVC2008

Wow, today is definitely not my day! But I found an article that says your have to remove

src/3rdparty/webkit/WebCore/tmp/moc/{debug,release}_shared/mocinclude.tmp

and

src/script/tmp/moc/{debug,release}_shared/mocinclude.tmp

and rerun nmake. The guy had the same error like you and for him it works. You can give it a try.

[vbman213]

I'm trying again...

I also configured:

"configure -nomake demos -nomake examples"

and ran nmake sub-src

I think that will speed up the build time as it is ignoring the examples and demos
