How to Install QT3 Runtime Library – Software Installation Guide

If you read the install.sh script, you'll notice:

function check_qt3
{
  QT3LIB=$(find /usr/lib -name "libqt-mt.so*")
  echo $QT3LIB
  if [ "$QT3LIB" ];then
      echo "check QT3 Runtime Library successfully."
  else
       mymessagebox "Sorry This software will not run until you install "QT3 Runtime Library". You can refer to Operaing System installation CD or Homepage to find out the QT3 Runtime Library installation package. This installation process will not continue until you install QT3 Runtime Library first."
  exit -1
fi
}

The script checks the /usr/lib/libqt-mt.so*. If the file is not found, the message will prompt you to install Qt3. After this, installation can continue.

Theme_Name="SteamBP"            
Theme_Definition_File="theme.txt"
