Mini2440, UBUNTU, ARM-LINUX-GCC: ld: cannot find -lqtopia2

 

Hello everybody!
I’m a new user of UBUNTU, FORUM, and Mini2440 Platform.

I known all 2 mounth ago and I must develop with this.

I have a problem: I can’t start beacause I never compile example project
“Hello”.

I have done a virtual machine with Virtual Box on Windows7 64bit and I have
install and upgrade UBUNTU 11.10.

With terminal I try to compile the “Hello” example from CD and I read so:

ubuntu@ubuntu-VirtualBox:~$ cd

ubuntu@ubuntu-VirtualBox:~/opt/FriendlyARM/mini2440/arm-qtopia/hello$ ls

You must have the qtopia libs in one of the folders listed by (type in your ubuntu terminal):

  1. echo $LD_LIBRARY_PATH

You can find where the qtopia is installed by typing:

  1. sudo updatedb
  2. locate libqtopia

Hi!
First of all, thank you very much for your reply!

Now I try your code from terminal and I have this:

  1. ubuntu@ubuntu-VirtualBox:~$ echo $LD_LIBRARY_PATH
  2.  
  3. ubuntu@ubuntu-VirtualBox:~$ sudo updatedb
  4. ubuntu@ubuntu-VirtualBox:~$ locate libqtopia
  5. /home/ubuntu/opt/FriendlyARM/mini2440/arm-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/lib/libqtopia.prl
  6. /home/ubuntu/opt/FriendlyARM/mini2440/arm-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/lib/libqtopia2.prl
  7. /home/ubuntu/opt/FriendlyARM/mini2440/arm-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/lib/libqtopiacalc.prl
  8. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopia.so
  9. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopia.so.1
  10. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopia.so.1.6
  11. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopia.so.1.6.3
  12. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopia2.so
  13. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopia2.so.2
  14. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopia2.so.2.1
  15. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopia2.so.2.1.0
  16. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopiacalc.so
  17. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopiacalc.so.2
  18. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopiacalc.so.2.2
  19. /home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/libqtopiacalc.so.2.2.0

Now what can I do?

If can help, this is “qmake.conf” file:

Your problem is linking, the compiler (linux-arm-g++) can’t find the libqtopia2.so.

The “echo $LD_LIBRARY_PATH” show the current “dynamic libraries available for linking”, as you can see in your post (May 2, 2012) the echo $LD_LIBRARY_PATH command reports nothing.

Try to type ih the ubuntu terminal:

  1. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ubuntu/opt/FriendlyARM/mini2440/rootfs_qtopia_qt4/opt/Qtopia/lib/
  2.  
  3. sudo ldconfig

In your post (may 1, 2012) the compiler can’t find libqtopia: “cannot find -lqtopia2”
With the above “export”, the compiler will be able to link your program with libqtopia.
