On this page, we get you up and running with Sentry's SDK.

Don't already have an account and Sentry project established? Head over to sentry.io, then return to this page.

Sentry captures data by using an SDK within your application’s runtime.

The Qt integration is part of the sentry-native SDK, which currently supports Windows, macOS, and Linux. Both Qt 5 and Qt 6 are supported.

To build the SDK, download the latest sources from the Releases page. The SDK is managed as a CMake project, which additionally supports several configuration options, such as the backend to use.

To enable the Qt integration set the SENTRY_INTEGRATION_QT option to YES.

For example (on macOS):

# Configure the cmake build into the `build` directory,
# with crashpad, and Qt integration (on macOS).
cmake -B build \
    -D SENTRY_BACKEND=crashpad \

# Build the project
cmake --build build --parallel

# Install the resulting artifacts into a specific prefix
cmake --install build --prefix install

# Which will result in the following (on macOS):
exa --tree install --level 2
├── bin
│  └── crashpad_handler
├── include
│  └── sentry.h
└── lib
   ├── cmake
   ├── libsentry.dylib
   └── libsentry.dylib.dSYM

You can configure the Qt build for Windows analogous to the regular build instructions.

Configuration should happen as early as possible in your application's lifecycle.

#include <QtWidgets>
#include <sentry.h>

int main(int argc, char *argv[])
    sentry_options_t *options = sentry_options_new();
    sentry_options_set_dsn(options, "https://examplePublicKey@o0.ingest.sentry.io/0");
    // This is also the default-path. For further information and recommendations:
    // https://docs.sentry.io/platforms/native/configuration/options/#database-path
    sentry_options_set_database_path(options, ".sentry-native");
    sentry_options_set_release(options, "my-project-name@2.3.12");
    sentry_options_set_debug(options, 1);

    // Make sure everything flushes
    auto sentryClose = qScopeGuard([] { sentry_close(); });

    QApplication app(argc, argv);
    QWidget widget;

    return app.exec();

Alternatively, the DSN can be passed as SENTRY_DSN environment variable during runtime. This can be especially useful for server applications.

This snippet includes an intentional error, so you can test that everything is working as soon as you set it up.

The quickest way to verify Sentry in your Native application is by capturing a message:

  /*   level */ SENTRY_LEVEL_INFO,
  /*  logger */ "custom",
  /* message */ "It works!"

To view and resolve the recorded error, log into sentry.io and open your project. Clicking on the error's title will open a page where you can see detailed information and mark it as resolved.
