LD_LIBRARY_PATH doesn't work without LD_PRELOAD

Question

I'm setting LD_LIBRARY_PATH to make newer Qt Mobility be used instead of the older one, so that the non-native apps can use it.

export LD_LIBRARY_PATH=/opt/qtm12/lib

One of the libraries is libQtSensors.so.1

but still,

/usr/lib/libQtSensors.so.1

is used instead of

/opt/qtm12/lib/libQtSensors.so.1

If I LD_PRELOAD the second library, everything is working, but I can't just preload all the qt mobility libraries, as it's not a library that is used always.

What am I doing wrong?

I'm using this on Maemo. LD_DEBUG=all tells nothing. Adding /opt/qtm12/lib to /etc/ld.so.conf.d/somefile.conf fixes nothing it seems that /usr/lib etc. stuff is taken if lib from other location is not preloaded — marmistrz, Aug 18 '12 at 14:54

$echo "/opt/qtm12/lib/" > /etc/ld.so.conf.d/qtm12.txt

$ldconfig -v

Still the /usr/lib/ versions of libraries are used – marmistrz Aug 31 '12 at 12:44
Then i would say put /opt/qtm12/lib/ in /etc/ld.so.conf in first line. http://linux.101hacks.com/unix/ldconfig/ – Satish Aug 31 '12 at 14:27
