Jom is clone of Microsoft Nmake and it just supports running multiple commands in parallel. This same thing does Qt creator, passes same parameters to QMake and then afterwords calles JOM make tool to compile from those make files. Windowsįor a Windows it would be: C:\QT5_build\bin\qmake.exe -r spec C:\QT5_build\mkspecs\win32-msvc2010īy specifying "win32-msvc2010" I am telling Qmake to generate Make file for Visual Studio 2010 compiler. In first step execute your Qmake against your project file to generate make files. Forward slash must be used for both Windows and OS X. Make qt.conf text file and save it into "bin" folder where Qmake executable is. Since we are not using installed version of Qt we need to instruct Qmake where hour Qt headers and libraries are.
QT MAC OS X PRO
pro project file and based on your settings it will generate Make, Make.Debug and Make.Release files. Let us assume we copied Qt installation on following locations C:\QT5_build for Windows and /Users/yourname/QT5_build for OS X.
QT MAC OS X HOW TO
Bin subfolder contains various tools such as aforementioned Qmake and uic, lib folder is where Qt prebuild libraries lie, include folder contains header files and "mkspecs" folder contains instructions for Qmake how to build make file for each particular compiler. To be able to build Qt from command line you will entire content from this folder. In case of Windows installation this folder will be called for example "msvc2010" if you have version for Visual Studio 2010 C++ compiler. In my case I had Qt 5.2.0 and under 5.2.0 folder which is a version there is "clang_64" folder and this means this Qt was build with/for clang 64bit compiler (not to go into many details here).
QT MAC OS X INSTALL
It is definitely easier to download installer and install it locally and copy content from there. Basically you have different compilers plus different operating system you need to compile for, it adds up.
QT MAC OS X CODE
Building from source can take hours even if you exclude components you don't need such as example code etc. Building from source can be very time consuming and frustrating. One way is to install on local system and copy content of the installation or to build from source. To be able to compile your application outside qt creator you will need content from Qt installation. If you click on Projects icon inside Qt creator you can see this steps with command line parameters being used. Make is essentially tool that based on configuration in background calls compiler which eventually compiles your code into library or executable for particular underlaying operating system. pro project file and create universal make file which can be compiled with any extern make program. Inside Qt installation "bin" folder there is a tool named "qmake". How Qt creator and actual qt build process works is quite simple.
QT MAC OS X MAC OS X
This tool will come later become my problem on Mac Os X system. h files which all C++ compilers can actually recognise and compile. Qt has a special tool inside it's bin directory call "uic" or "uic.exe" depending on which system and this executable is responsible for converting those UI files into "reasonable" C++ code, normally into. Those files are basically xml files describing your UI, windows, controls etc. Alongside your standard C++ files you will probably have UI files if you are building application with windows.
This file is very basic version of make file, but it's NOT. pro file which is basically your project file where you define you build settings, which files you want to build, c, c++, h etc. Python script should get latest code from source control and basically build Qt project from command line with same code on both Windows and Mac Os X. Whole idea is to make build and deployment process self sufficient and easy to maintain. In my particular case application is hosted on TeamFoundation server and code is being pulled and build from there using Python scripts. There are several different reasons why you don't want to install Qt on each machine you are building it on. What to do if you want to automate this process and you can't install Qt on your, let us assume, build machine. You have your Qt installation on your system either Windows, Linux or Mac Os X, doesn't really matter as long as you are compiling your application from Qt creator. Let us assume you have a project build with Qt version 5.x.
