Reg - Conversion of Qt3 to Qt4
dear all,
Now i am trying to convert the Qt3.3.4 files into Qt4.1.4. After Executing Qt3to4 in cmd mode it gives the following some errors.
D:/Qt/4.1.4/include/QtCore\../../src/corelib/thread/qthread.h(31) : error C2146: syntax error : missing ';' before identifier 'QT_MODULE'

All errors shows in qt include files. give any solutions.

Re: Reg - Conversion of Qt3 to Qt4
Why does it include both Qt3 and Qt4 headers?
Re: Reg - Conversion of Qt3 to Qt4
I set only Qt4 includes in environment variables.
Re: Reg - Conversion of Qt3 to Qt4
Check your project --- maybe path to Qt3 is set somewhere. Make sure you use Qt4 tools and double check your enviroment variables (echo %PATH% and so on).
Re: Reg - Conversion of Qt3 to Qt4
I crosschecked the environment variables and vc++ settings. i couldn't find the Qt3 include. Is there any possibility in somewhere because previously i was working with Qt3

Re: Reg - Conversion of Qt3 to Qt4
Did you run "make clean"? Which file do you get those errors for?

After running "make clean" the following errors occured.

I don't see any errors.

If your Makefile knows something about image collections, then it isn't a Qt4 Makefile --- generate a new one and try again.

Not true. uic3 will create a qmake_image_collection.cpp from an IMAGES variable in the .pro file.
Like Qt3Support, this is a porting aid. You want to use resources instead of IMAGES in your finished project, but since you can't do everything at once, it's a helpful tool to get you there.
Re: Reg - Conversion of Qt3 to Qt4
Atlast I found my error. In vc++ Directories Qt3 path set. I changed and now it works fine.
Thanks to Jacek and Brandybuck.

Probably you are right, but I don't remember that IMAGES did work when I was porting my apps to Qt4. It was some time ago, so either I don't remember well, or something has changed.
Anyway there is no IMAGES variable in Qt4 docs (there's FORMS3 only).
