Qt 4.7.4 build problem

Environment:

- Windows Vista
- Qt 4.7.4 commercial
- MSVC 2008

Tried to build using the following commands:

c:/Qt/>PATH=C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin; \

Some incompatibilities there? Ideas?

Re: Qt 4.7.4 build problem

qt_dynamic_cast_check probably needs rtti.

oh hello there,

Could it be any more clear?

See attached screenshot for where to turn on RTTI in VS 2008. If you're using a Makefile, then you need to add -GR to the cl command options.

Yes, indeed, I saw that message.

I was actually looking for a different type of response, one like: "No, Qt cannot be built with the '-no-rtti' option;" or maybe "Oops, there's a bug in the shader package and the fix is..."

Turns out the correct answer is #2 - there's a bug in Qt shader package. I received a fix from Digia and successfully (re-)built with '-no-rtti' option.
