I'm building using scratchbox. I've installed the qt4-experimental packages in
both scratchbox and on my N900.
[sbox-FREMANTLE_ARMEL: ~/qt-mobility-1.0.2] > which qmake
/opt/qt4-maemo5/bin/qmake
[sbox-FREMANTLE_ARMEL: ~/qt-mobility-1.0.2] > ./configure -modules sensors
Configuring Qt Mobility
Checking available Qt ... 4.7.0
Checking QMF ... Not Found
Checking NetworkManager ... Not Found
Checking CoreWLAN (MacOS 10.6) ... Not Found
Checking Maemo ICD ... Not Found
Checking Maemo ICD WLAN ... OK
Checking Maemo5 contacts dependencies ... OK
Checking Bluez ... OK
Generating Mobility Headers...
I didn't install any qt-mobility libraries because they depend on 4.6 and my
code depends on 4.7.
After compilition (make install), the install /qt-mobility-1.0.2/install
directory has the following contents:

I copied these files to the n900 /opt/qt4-maemo5/
Nokia-N900:/home/user# ./accel
Accelerometer didn't start!
Then I try to run accel and I get the error. Just as a sanity check, I ran
Nokia-N900:/home/user# ldd accel
