Qt Mobility 1.1.0: Build fails in systeminfo component

[joejoejoejoe]

I am trying to compile Qt Mobility 1.1.0 (final) on Ubuntu 64bit with Qt 4.7.1 and the build always fails in the 'systeminfo' component.

It seems to me that two includes have been forgotten in 'src/systeminfo/qsysteminfo_linux_common.cpp': The first one is
@ include <math.h>@ and the second one
@include <QSocketNotifier>@
If I add both of them to the above file, compilation works fine.

Has anyone else encountered this issue?

I have and your solution worked for me aswell. Platform for installation was MeeGo 1.1

Thank you!

I ran into this exact problem as well. Adding those header files allowed it to build without a hitch. My environment is Debian 64-bit with Qt 4.7.1.

Also had the problem, but your solution worked. Thank you!

Env:
Ubuntu 10.10 / Maverick Meerkat
Qt 4.7.1
QtMobility 1.1.0 (final)
