How to compile qtsparkle

mkdir bin
cd bin
cmake ..
make

Arguments to cmake

• -DCMAKE_BUILD_TYPE=[Release|Debug] A Release library will be smaller but won't contain any debugging symbols.
• -DBUILD_SHARED_LIBS=[ON|OFF] Set this to ON to produce a .dll or .so, OFF to produce a .a. Defaults to OFF.
• -DCMAKE_TOOLCHAIN_FILE=path Useful when cross-compiling. See below for a toolchain file for using mingw32 on Linux.
• -DQT_HEADERS_DIR=path
• -DQT_LIBRARY_DIR=path Useful when cross compiling or if cmake can't find your Qt installation.

mingw32 CMake toolchain file

Put the following in a .cmake file and point to it with -DCMAKE_TOOLCHAIN_FILE when compiling.

# the name of the target operating system
SET(CMAKE_SYSTEM_NAME Windows)

# which compilers to use for C and C++
SET(CMAKE_C_COMPILER i586-mingw32msvc-gcc)
SET(CMAKE_CXX_COMPILER i586-mingw32msvc-g++)

# here is the target environment located
SET(CMAKE_FIND_ROOT_PATH  /target )

How to use qtsparkle from your application

See the exampleapp folder for a basic Qt application that uses qtsparkle. You should create a qtsparkle::Updater in your application's main window, it will check for updates as soon as your application returns to the event loop.

#include <qtsparkle/Updater>

MainWindow::MainWindow() {
    qApp->setApplicationName("ExampleApp");
    qApp->setApplicationVersion("1.2");

    qtsparkle::Updater* updater = new qtsparkle::Updater(
        QUrl("http://www.example.com/sparkle.xml"), this);

    connect(ui_->check_for_updates, SIGNAL(clicked()),
            updater, SLOT(CheckNow());
}

For Qt5 you need to use #include <qtsparkle-qt5/Updater>.
