The message is 'LINK : fatal error LNK1104 can not open file QtGuid.lib'.
I found that the QtGui.lib was exist.
I do not know why?

Does the error occur while building Qt or does it occur when building an application using Qt? Does the linker know where to look for QtGuid.lib?

If you are using visual studio you should add the search path for Qt libraries to your environment options. qmake should know where the libraries are.

Which compiler version? I've built Qt 4.5.2 for MSVS 2008 twice now without any problems.

If you are building Qt from nmake, you may have to build it 2 times to get the whole thing to compile. At least this is what has happened to me. The first time you get errors because moc was not created. The second time everything builds. I am not sure if this is related though. Although I have built Qt on a dozen or so machines I have not done so in months.

Windows XP is not a compiler but an operating system (more or less). Please explain the exact steps you take to build Qt, including any command line stuff, like your configure step.
