I'm trying to build a Qt-based browser on OS X 10.7.3 using the source code from the developer in Git format. I have installed Xcode 4.3.1 including the command line tools. I have also downloaded and installed Qt 4.8.0 from Qt.mpkg. The build instructions are no more than run the following three commands: qmake make sudo make install Note that with the very same source code, these three commands work perfectly in Ubuntu Linux. However, although qmake seems to do something on the Mac, when I try the make command, I get this output: make: *** No targets specified and no makefile found. Stop. Perhaps I don't quite have the correct Qt tools. Can anybody suggest where I might be going wrong?
