+If those steps don't work for you, here are some common problems:

+Compilations fails with along the lines of:
+axis.h:21: error: expected class-name before ‘{’ token
+axis.h:22: error: ISO C++ forbids declaration of ‘Q_OBJECT’ with no type
+axis.h:24: error: expected ‘;’ before ‘friend’
+axis.h:29: error: ‘QTextStream’ has not been declared
+axis.h:31: error: ‘QTextStream’ has not been declared
+axis.h:40: error: ‘QString’ does not name a type
+axis.h:44: error: ‘QString’ does not name a type
+axis.h:89: error: ISO C++ forbids declaration of ‘QTimer’ with no type
+
+Most likely you're using the Qt3 version of qmake; QJoyPad needs to use Qt4 to 
+work properly.  The config script is supposed to detect this properly, but in
+the event it fails you should find what the proper executable is (if you think
+you've found it run it with the --version option to make sure it is for Qt
+4.0 or greater).  Then rerun the config script with the --qmake4bin=BIN option,
+where BIN is the executable name of the proper qmake binary, or a path to the
+proper qmake binary.
