Compiling error with caps file names

[Caius Aérobus]

I have problems with a #include <QDomElement> line in a library (file not found). The file is here but it seems that the compiler does not make the translation QDomElement -> qdomelement.h
Where is the problem?

did you set path to Qt's includes?

[Caius Aérobus]

yes but it seems that it is now necessary to include QT/XML path...

[spirit]

did you add QT += xml to your pro-file?

[Caius Aérobus]

No because it works without it on my MacOSX computer but I have this problem on Linux Ubuntu and I suppose the reason is here. I will check it ASAP.

let's look to documentation:

To include the definitions of the module's classes, use the following directive:
#include <QtXml>
To link against the module, add this line to your qmake .pro file:
QT += xml
