Cross compiling library not found

[refik]

Dear all,

I am getting an error (probably a beginner error), however I can't resolve it on my own. I looked online for similar problems and their solutions and tried to incorporate them into the qmake file but it didn't work, I get always the same error.

So, what is my problem about. I am trying to cross compile Qt libraries 4.7.4 for embedded Linux on Ubuntu 11.04 (I also tried on 11.10 in a virtual machine but I got the same error), I tried to cross compile it using the arm-linux-gnueabi-gcc-4.4 and arm-linux-gnueabi-g++-4.4. My qmake configuration file looks like this:

My configuration which I run:

@
./configure -opensource -confirm-license -prefix /opt/qt-arm -no-qt3support -embedded arm -little-endian -xplatform qws/linux-DM3730-g++ -platform qws/linux-x86-g++ -release -qtlibinfix E
@
(I have also tried without the "-platform qws/linux-x86-g++" )

And the error I get after I type in "make" (maybe after 30-45 minutes of time):

If I understood the error message correctly, the library "libc.so" is missing, however I can find it in "/usr/arm-linux-gnueabi/lib". So I created a file "sudo vim /etc/ld.so.conf.d/my.conf" and added the following:
@

Lib for ARM

/usr/arm-linux-gnueabi/lib
/usr/arm-linux-gnueabi/include
@
And then I typed in: sudo ldconfig -v
And tried with make confclean and same configuration as above, however I got the same error. So I assume it is something I am doing wrong of which I am not even aware of?

Did anyone have a similar error, and if how did he solve it?

Thank you all. I am looking forward for you help.

Best regards,
Refik
