Problem with Qt-4.6.2

[geovanyfilho]

Hi,

I get the following problem when I try to run an application on Qt 4.6.2 for embedded Linux:

relocation error: /usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/libQtGui.so.4: symbol powf, version GLIBCXX_3.4 not defined in file libstdc++.so.6 with link time reference

The config I used to compile qt is:

./configure -opensource -no-largefile -exceptions -no-accessibility -stl -no-qt3support -no-xmlpatterns -no-multimedia -no-phonon -no-phonon-backend -svg -no-webkit -no-javascript-jit -no-script -no-scripttools -no-openssl -nomake examples -nomake demos -nomake docs -embedded arm -little-endian -no-opengl -no-openvg

If I try it with Qt 4.6.0 I have no problem. Any ideas?

thank you,

What libc do you have installed?

What libc do you have installed?

I'm crosscompiling qt... On my host I have libc-2.5 in the lib of the crosscompiler, but on my target I have libc-2.7

Should it be the problem?
I'll update my crosscompiler lib and try again...

thank you

I was not able to find a crosscompiler with libc-2.7.
I compiled qt 4.6.0, 4.6.1 and qt 4.6.2 with the same configuration, and tried to run the same application, but it only succed with qt 4.6.0.
Qt 4.6.1 and 4.6.2 give me the same error related before.
Once qt 4.6.0 gives me no error, I think some of the changes on qt 4.6.1+ is causing the error.
