[Qt-embedded-interest] problems in configuring 'qvfb'

[Avishek_Sharma]

Hi Markus,
   Thank you for the reply....need some help in locating 'libXtst' library in my system.I am not familiar with Linux directory structure so,no clue as to which directory the 'libXtst' library is present in.I made a few attempts to find 'lxtst'/'libXtst ' but didn't get any results.
I tried using 'find / -name lX*' and 'locate lXtst' (which shows nothing) and 'locate libXtst'(which shows the files in the 'libXtst' folder I downloaded from the internet).

Also,need some clarification on the methods to solve the issue---
first, where do I find 'LD_LIBRARY_PATH' environment variable.I guess it will be in some file in /root...but,no idea where.
secondly,how do I make qmake aware of 'libXtst's location....do I have to do something like this---
qmake -L <PATH_TO_LXTST> -lXtst  qvfb.pro.

I doubt I got it right.....please advice.A code snippet would be very helpful.
Thank you for your time.

regards,
Avi

This indicates that the library is already installed. The problem in your case is that qmake doesn't find it in the right path. You have several options to fix that:

1. copy the library in a directory which is contained in your LD_LIBRARY_PATH environment variable
2. make qmake aware of the path where libXtst is located
3. you can simply add "-L<PATH_TO_LXTST>" right in front of the "-lXtst" option of the linker call and then invoke this command manually, that means
