Static build of Qt-embedded applications

[cloud]

Hi all,

I'm trying to cross-compile an application statically linked to Qt-Embedded (open-source license).
My host is Ubuntu Linux 32-bit on a PC. My target is Linux running on a ARM9.

I dowloaded Qt-embedded and built them using:

./configure -release -static -no-largefile -no-accessibility -embedded arm -xplatform qws/linux-arm-g++ -prefix <destinazione> -little-endian -no-mmx -no-3dnow -no-sse -no-sse2 -opensource -no-qt3support -no-webkit -no-openssl -silent -no-cups -no-opengl -qt-gfx-linuxfb

This is supposed to build a static version of QT libraries, isn't it ?

Then, I modified the mkspecs/common/g++.conf file, adding -static to QMAKE_LFLAGS.

However, when compiling the application, I get several errors:

Any help will be very appreciated.

Many thanks.

You should not need to modify the mkspec. Passing -static to configure is enough. It will be inherited to your applications makefile as well. The error messages look like there is no QtNetwork.a. Do you have one?
