Hi all.
I created a program with qtembedded for mini6410 board, but the error is
occurring undefined symbol: _ZTI11QMainWindow.

running the command FILE

ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses
shared libs), for GNU/Linux 2.6.14, not stripped

already tried many things but I am newbie with linux, someone could help
please!

Try:

readelf -A <file> or -a and look at the end of the file to see which arm
variant is called.

davef 
undefined symbol - some library not included?

Juergen Beisert 
Did you compile the library and your application with the same compiler?
C++ name mangeling may change from version to version.

Diego 
davef thanks for your help!
with comand    readelf -A <file>    received the following data

this is what is causing the error?

Juergen,
I created the tools based on this tutorial

Many thanks

Is the mini6410 armv4t?  I know the mini2440 is, but thought the mini6410
was different.

Juergen Beisert 
The Mini2440 uses an S3C2440 SoC, which contains an ARMv4T core. The
Mini6410 comes with an S3C6410 SoC, which contains an ARMv6ZK core.

Diego: welcome to the world of binary copy here and there, build something
with one toolchain, something different with a different toolchain, copy
everything together and hope it will run. Maybe it will. Most of the time
it wont.
If you want to develop your own application and keep your frustration level
low, start with one of the available cross build systems. They will provide
you with a consistent root filesystem for your target. Its harder to start,
because you must first learn how to use and configure these kind of tools.
But its really worth the effort.
