[ptxdist] qt4 - openssl support: symbol lookup error: undefined symbol: _ZN10QSslSocket11supportsSslEv

[Matthias Klein]

Hello,

in a working BSP project I need SSL support in QT4. Therefore I have 
enabled PTXCONF_QT4_OPENSSL.
I have rebuiled QT4 without problems by clean & targetinstall.

In a small test application I tried to verify SSL:

#include <QSslSocket>
     if(QSslSocket::supportsSsl())
...

The app compiles fine, but when I run them on the target I get:

./sslTest: symbol lookup error: ./sslTest: undefined symbol: 
_ZN10QSslSocket11supportsSslEv


I tried to verify that the function is in the Network library of Qt:

$ arm-cortexa8-linux-gnueabihf-objdump -d 
platform-tx53/root/usr/lib/libQtNetwork.so | grep supportsSsl
    2c428: eb0215f4  bl b1c00 <_ZN10QSslSocket11supportsSslEv>
    abea8: eb001754  bl b1c00 <_ZN10QSslSocket11supportsSslEv>
    afe58: eb000768  bl b1c00 <_ZN10QSslSocket11supportsSslEv>
    afed8: eb000748  bl b1c00 <_ZN10QSslSocket11supportsSslEv>
    b07cc: eb00050b  bl b1c00 <_ZN10QSslSocket11supportsSslEv>
For me it looks OK.


Then I did a complete ptxdist distclean & go cycle for safety, but the 
result is the same ...
Besides SSL QT4 runs fine on the target. (The BSP use ptxdist-2013.09.0 
& OSELAS Toolchain 2012.12.1 arm-cortexa8-linux-gnueabihf)


Did I something wrong ?
Any tips what I can do / investigate ?


Best regards,

Matthias

Are you using NFSroot? Or: is the "platform-tx53/root/usr/lib/libQtNetwork.so" 
the same library as your "sslTest" application "sees" at runtime?
