$ wget --quiet http://download.qt-project.org/official_releases/qt/5.2/5.2.1/qt-opensource-windows-x86-msvc2012_64_opengl-5.2.1.exe
$
As seen above, I first downloaded the Qt package for Visual Studio in a Cygwin Bash shell.
A sidenote: The Qt library packaged within Cygwin is not useful for me because I need to use the Visual Studio C++ compiler.
First I set the correct permissions on the file
$ chmod 755 qt-opensource-windows-x86-msvc2012_64_opengl-5.2.1.exe
If I start it like this
$ ./qt-opensource-windows-x86-msvc2012_64_opengl-5.2.1.exe
a graphical window (GUI) is shown but that is not what I want as I would later like to have the installation procedure written into a Bash script that I could run in Cygwin.
If I add the option --help, like this
$ ./qt-opensource-windows-x86-msvc2012_64_opengl-5.2.1.exe --help
a new terminal window is opened with the following text
Usage: SDKMaintenanceTool [OPTIONS]
User:
--help Show commandline usage
--version Show current version
--checkupdates Check for updates and return an XML file describing
the available updates
--updater Start in updater mode.
--manage-packages Start in packagemanager mode.
--proxy Set system proxy on Win and Mac.
This option has no effect on Linux.
--verbose Show debug output on the console
--create-offline-repository Offline installer only: Create a local repository inside the
installation directory based on the offline
installer's content.
Developer:
--runoperation [OPERATION] [arguments...] Perform an operation with a list of arguments
--undooperation [OPERATION] [arguments...] Undo an operation with a list of arguments
--script [scriptName] Execute a script
--no-force-installations Enable deselection of forced components
--addRepository [URI] Add a local or remote repo to the list of user defined repos.
--addTempRepository [URI] Add a local or remote repo to the list of temporary available
repos.
--setTempRepository [URI] Set a local or remote repo as tmp repo, it is the only one
used during fetch.
Note: URI must be prefixed with the protocol, i.e. file:///
http:// or ftp://. It can consist of multiple
addresses separated by comma only.
--show-virtual-components Show virtual components in package manager and updater
--binarydatafile [binary_data_file] Use the binary data of another installer or maintenance tool.
--update-installerbase [new_installerbase] Patch a full installer with a new installer base
--dump-binary-data -i [PATH] -o [PATH] Dumps the binary content into specified output path (offline
installer only).
Input path pointing to binary data file, if omitted
the current application is used as input.
I don't know how to continue from here. Do you know how I could install the Qt 5.2.1 library (for Visual Studio) from the Bash shell in Cygwin?
Update: The advantage of writing the build script for a Cygwin environment is that commands like git, wget, and scp are available. This Stackoverflow answer describes how to invoke the MSVC compiler from a Cygwin bash script. Note, that the Qt application I'm building is not going to have any dependency on Cygwin.
I didn't test with Cygwin but I successfully installed Qt5.5 using a script. To do so, you must use the --script line of the normal installer.
.\qt-opensource-windows-x86-msvc2013_64-5.5.1.exe --script .\qt-installer-noninteractive.qs
Here's an example of qt-installer-noninteractive.qs file I used in the command above
function Controller() {
installer.autoRejectMessageBoxes();
installer.installationFinished.connect(function() {
gui.clickButton(buttons.NextButton);
})
}
Controller.prototype.WelcomePageCallback = function() {
gui.clickButton(buttons.NextButton);
}
Controller.prototype.CredentialsPageCallback = function() {
gui.clickButton(buttons.NextButton);
}
Controller.prototype.IntroductionPageCallback = function() {
gui.clickButton(buttons.NextButton);
}
Controller.prototype.TargetDirectoryPageCallback = function() {
gui.currentPageWidget().TargetDirectoryLineEdit.setText("C:/Qt/Qt5.5.1");
gui.clickButton(buttons.NextButton);
}
Controller.prototype.ComponentSelectionPageCallback = function() {
var widget = gui.currentPageWidget();
widget.deselectAll();
widget.selectComponent("qt.55.win64_msvc2013_64");
// widget.selectComponent("qt.55.qt3d");
// widget.selectComponent("qt.55.qtcanvas3d");
// widget.selectComponent("qt.55.qtquick1");
// widget.selectComponent("qt.55.qtscript");
// widget.selectComponent("qt.55.qtwebengine");
// widget.selectComponent("qt.55.qtquickcontrols");
// widget.selectComponent("qt.55.qtlocation");
gui.clickButton(buttons.NextButton);
}
Controller.prototype.LicenseAgreementPageCallback = function() {
gui.currentPageWidget().AcceptLicenseRadioButton.setChecked(true);
gui.clickButton(buttons.NextButton);
}
Controller.prototype.StartMenuDirectoryPageCallback = function() {
gui.clickButton(buttons.NextButton);
}
Controller.prototype.ReadyForInstallationPageCallback = function()
{
gui.clickButton(buttons.NextButton);
}
Controller.prototype.FinishedPageCallback = function() {
var checkBoxForm = gui.currentPageWidget().LaunchQtCreatorCheckBoxForm
if (checkBoxForm && checkBoxForm.launchQtCreatorCheckBox) {
checkBoxForm.launchQtCreatorCheckBox.checked = false;
}
gui.clickButton(buttons.FinishButton);
}
The tricky part was to found the id of the components! I was able to found the right id qt.55.win64_msvc2013_64 by adding the flag --verbose and installing it normally with the UI and stopping at the last page; all the ids that you selected for installation are there.
There is slightly more information in this answer if you need more details.
EDIT (29-11-2017): For installer 3.0.2-online, the "Next" button in the "Welcome" page is disabled for 1 second so you must add a delay
gui.clickButton(buttons.NextButton, 3000);
EDIT (10-11-2019): See Joshua Wade's answer for more traps and pitfalls, like the "User Data Collection" form and "Archive" and "Latest releases" checkboxes.
