Reece,

OK, so it looks better, the rsp file contains a line for each of the 3
QT libraries, but also adds three extra lines similar to this:

"last of my objects ..."

<l/msvc-7.1/debugthreading-multi>qtmain
<l/msvc-7.1/debugthreading-multi>QtCore
<l/msvc-7.1/debugthreading-multi>QtGui

"qtmaind"
"QtCored4"
"QtGuid4"

<- end of the file here...

Understandably the linker objects to
<l/msvc-7.1/debugthreading-multi>qtmain "cannot open file" :-)
Interestingly this was for a debug compile, the correct lines feature
the required "qtmaind" not qtmain, and the needed "QtCored4" not
QtCore, etc.

(as well as a couple of blank lines - very minor)

I'm compiling my exe using the following form of reference to Qt...

exe myapp : main.cpp myuifile.ui /Project/sub-library//foo :
<library>/qt4//QtGui ;

using VC 7.1

Thanks

Kevin
