Hello:

I have an application [mscore] that will only compile against Qt 4.6.
I can successfully compile, install and run it on the same system with Qt 4.6.1 installed, however if I install the same compiled app on a system with Qt 4.5.3 installed the application will not start and produces the following error;
Qt Code: 
  1. [seve@larissa ~]$ mscore
  2. mscore: symbol lookup error: mscore: undefined symbol: _ZN11QVectorData8allocateEii
To copy to clipboard, switch view to plain text mode 
Other info
Qt Code: 
  1. Build Host - Qt version 4.6.1 
  2. Client Machine - Qt version 4.5.3
  3. The build host and the client are x86_64 Fedora 12 running the same kernel 2.6.31.12-174.2.3.fc12.x86_64
To copy to clipboard, switch view to plain text mode 

I'm not a programmer and as such I have no idea what the error means so any help would be greatly appreciated.

Thanks
