Why is there a special problem with QtSVG during installation?

[MattPhillips]

This is for Windows, Qt 4.7.2, Qwt 6.0.0, MinGW. I'm installing from the command line, run qmake (get a warning about deprecated unescaped backslashes, which I'm ignoring), and then when I make, everything compiles but the linker fails because it can't find -lQtSvgd. I've checked the Qt lib directory and the SVG libraries are there along with the rest. I've also added QT += svg to the qwt.pro file, it doesn't make a difference. This happened attempting to build both debug and debug_and_release versions; I haven't touched anything else in the .pri files. The Qt install is default--debug and shared. Anybody know what I need to do here?

Disable "CONFIG += silent" in qwtbuild.pri and do another make. Then check the command that is used for linking.

Hi Uwe,

Here's the output with Config += silent commented out:

cd src\ && mingw32-make -f Makefile
mingw32-make[1]: Entering directory `C:/Users/matt/Projects/EBResearch/EBClient/qwt-6.0.0-rc5/src'
mingw32-make -f Makefile.Debug
mingw32-make[2]: Entering directory `C:/Users/matt/Projects/EBResearch/EBClient/qwt-6.0.0-rc5/src'

The error message follows this. So it's supplying g++ with the 'static' option? That looks like a big clue. But why? QWT_CONFIG += QwtDll is uncommented in the qwtconfig.pri.

So I seem to have 'resolved' this by recompiling/rebuilding qwt in another directory. I don't really get what the problem was but it's working now.
