Problems with last SDK an QT4

[nowhereman]

I'm developing an application using QT. And before installed the last version of SDK I didn't have any problem, compiling my application.

I try to compile a test application (hello.cpp) and it happens the same, it gives me an error:

[sbox-FREMANTLE_X86: ~/hello] > make

make: *** [hello] Error 1

Anybody have any idea how to fix this problem?

Thank you

Some classes have had their filenames changed case-wise (eg. QtSTUFF -> QtStuff) from 4.5 to 4.6. I can't remember which but try checking that.

Have you regenerated the makefile using qmake?

[nowhereman]

It's a complete new project. I mean, I copy hello.cpp from a tutorial, and then qmake -project and qmake ... nothing else ... And I reinstall sdk ... without delete previous one ...

It seems you got your Qt versions mixed up.
Perhaps you should delete the old SDK before installing a new one.
