I am NOT very expert in CMake and C++, but do have a background in compling software. Here's a partial explanation. The critical error is obviously the second one "fatal error". It is complaining that the file animation.h (which is "included", i.e. copied in, when you compile animation.cpp) is asking to include file QTimer (possibly with some "extension" such as ".h"_) from a system directory somewhere, and it didn't find it. A guess is that this library would be part of the QT4 development package. Note that the text file "INSTALL' supplied with QAvimator does say that you need to "install the QT4 development package". Several hypotheses are possible: - the previous error about the quotation mark indicates a problem that causes a failure to find QTimer. Note that the complaint is not about quotation marks in animation.cpp (or animation.h for that matter) but about the command line being used to compile animation.cpp. This command line is generated "on the fly" by make (or CMake) based on makefiles (ro Cmakefiles). I am not very expert on this. It is possible that there is an incompatibility between the CMake on the system and the makefiles. Notice that the INSTALL file says "install CMake 2.4+". - the QT4 development package is not installed. It is worrisome that the text "-I/usr/share/qt3....." occurs in the error message. It is possible that the compile is trying to use the QT3 development package rather than the QT4 development package. A quick look seems to indicate that QTimer is not a part of QT3, only QT4." - The compile is looking in the wrong place for the QTimer file. An example would be if it were looking in /usr/share/.... and the file is in /usr/include/.... For example, on my system, there is a file /usr/include/qt4/QtCore/QTimer, which would appear to be the file you are missing. First suggestion....track down whether the QT4 development package (development package, not just the library package....typically called something-dev or similar is installed. Good luck.
