In this +case there is just one file, \e hello.cpp. Most applications require +multiple files; this situation is dealt with by listing all the files +on the same line space separated, like this: +\code + SOURCES = hello.cpp main.cpp +\endcode + +Alternatively, each file can be listed on a separate line, by escaping +the newlines, like this: +\code + SOURCES = hello.cpp \ + main.cpp +\endcode + +A more verbose approach is to list each file separately, like this: +\code + SOURCES += hello.cpp + SOURCES += main.cpp +\endcode +This approach uses "+=" rather than "=" which is safer, because it +always adds a new file to the existing list rather than replacing the +list. + +The HEADERS line is used to specify the header files created for use +by the application, e.g. +\code + HEADERS += hello.h +\endcode + +Any of the approaches used to list source files may be used for header +files. + +The CONFIG line is used to give \e qmake information about the +application's configuration. +\code + CONFIG += qt warn_on release +\endcode + +The "+=" is used here, because we add our configuration options to any +that are already present. This is safer than using "=" which tqreplaces +all options with just those specified. + +The \e qt part of the CONFIG line tells \e qmake that the application +is built using Qt. This means that \e qmake will link against the Qt +libraries when linking and add in the neccesary include paths for +compiling. + +The \e warn_on part of the CONFIG line tells \e qmake that it should +set the compiler flags so that warnings are output. + +The \e release part of the CONFIG line tells \e qmake that the +application must be built as a release application. During +development, programmers may prefer to tqreplace \e release with \e +debug, which is discussed later. + +\omit +The last line in the project file is the TARGET line: +\code + TARGET = hello +\endcode +The target line simply specifies what the name of the target should be +for the application. You shouldn't put an extension here because \e +qmake will do this for you. +\endomit + +Project files are plain text (i.e. use an editor like notepad, vim +or xemacs) and must be saved with a '.pro' extension. The name of the +application's executable will be the same as the project file's name, +but with an extension appropriate to the platform. For example, a +project file called 'hello.pro' will produce 'hello.exe' on Windows +and 'hello' on Unix. + +\section1 Generating a makefile + +When you have created your project file it is very easy to generate a +makefile, all you need to do is go to where you have created your +project file and type: + +Makefiles are generated from the '.pro' files like this: +\code + qmake -o Makefile hello.pro +\endcode + +For Visual Studio users, \e qmake can also generate '.dsp' files, for +example: +\code + qmake -t vcapp -o hello.dsp hello.pro +\endcode |
