The Sentry Native SDK is an error and crash reporting client for native applications, optimized for C and C++. Sentry allows to add tags, breadcrumbs and arbitrary custom context to enrich error reports. Supports Sentry 20.6.0 and later.
Using the sentry-native SDK in a standalone use case is currently an experimental feature. The SDK’s primary function is to fuel our other SDKs, like sentry-java or sentry-unreal. Support from our side is best effort and we do what we can to respond to issues in a timely fashion, but please understand if we won’t be able to address your issues or feature suggestions.

The SDK can be downloaded from the Releases page, which also lists the changelog of every version.
The SDK bundle contains the following folders:
external: These are external projects which are consumed viagit submodules.include: Contains the Sentry header file. Set the include path to this directory or copy the header file to your source tree so that it is available during the build.src: Sources of the Sentry SDK required for building.
The SDK currently supports and is tested on the following OS/Compiler variations:
- 64bit Linux with GCC 9
- 64bit Linux with clang 9
- 32bit Linux with GCC 7 (cross compiled from 64bit host)
- 32bit Windows with MSVC 2019
- 64bit Windows with MSVC 2022
- macOS Catalina with most recent Compiler toolchain
- Android API29 built by NDK21 toolchain
- Android API16 built by NDK19 toolchain
Additionally, the SDK should support the following platforms, although they are not automatically tested, so breakage may occur:
- Windows Versions lower than Windows 10 / Windows Server 2016
- Windows builds with the MSYS2 + MinGW + Clang toolchain
The SDK supports different features on the target platform:
- HTTP Transport is currently only supported on Windows and platforms that
have the
curllibrary available. On other platforms, library users need to implement their own transport, based on thefunction transportAPI. - Crashpad Backend is currently only supported on Linux, Windows and macOS.
- Client-side stackwalking is currently only supported on Linux, Windows, and macOS.
The SDK is developed and shipped as a CMake project. CMake will pick an appropriate compiler and buildsystem toolchain automatically per platform, and can also be configured for cross-compilation. System-wide installation of the resulting sentry library is also possible via CMake.
Building the Crashpad Backend requires a C++14 compatible compiler.
Build example:
# configure the cmake build into the `build` directory, with crashpad (on macOS)
$ cmake -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo
# build the project
$ cmake --build build --parallel
# install the resulting artifacts into a specific prefix (use the correct config on windows)
$ cmake --install build --prefix install --config RelWithDebInfo
# which will result in the following (on macOS):
$ exa --tree install

Android:
The CMake project can also be configured to correctly work with the Android NDK, see the dedicated CMake Guide for details on how to integrate it with gradle or use it on the command line.
MinGW:
64-bits is the only platform supported for now. LLVM + Clang are mandatory here : they are required to generate .pdb files, used by Crashpad for the report generation.
For your application to generate the appropriate .pdb output, you need to activate CodeView file format generation on your application target. To do so, update your own CMakeLists.txt with something like target_compile_options(${yourApplicationTarget} PRIVATE -gcodeview).
If you use a MSYS2 environement to compile with MinGW, make sure to :
- Create an environement variable
MINGW_ROOT(ex :C:/msys64/mingw64) - Run from
mingw64.exe:pacman -S --needed - < ./toolchains/msys2-mingw64-pkglist.txt - Build as :
# Configure with Ninja as generator and use the MSYS2 toolchain file
$ cmake -GNinja -Bbuild -H. -DCMAKE_TOOLCHAIN_FILE=toolchains/msys2.cmake
# build with Ninja
$ ninja -C buildMacOS:
Building universal binaries/libraries is possible out of the box when using the
CMAKE_OSX_ARCHITECTURES define, both with the Xcode generator as well
as the default generator:
# using xcode generator:
$ cmake -B xcodebuild -GXcode -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64"
$ xcodebuild build -project xcodebuild/Sentry-Native.xcodeproj
$ lipo -info xcodebuild/Debug/libsentry.dylib
Architectures in the fat file: xcodebuild/Debug/libsentry.dylib are: x86_64 arm64
# using default generator:
$ cmake -B defaultbuild -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64"
$ cmake --build defaultbuild --parallel
$ lipo -info defaultbuild/libsentry.dylib
Architectures in the fat file: defaultbuild/libsentry.dylib are: x86_64 arm64Make sure that MacOSX SDK 11 or later is used. It is possible that this requires
manually overriding the SDKROOT:
$ export SDKROOT=$(xcrun --sdk macosx --show-sdk-path)The following options can be set when running the cmake generator, for example
using cmake -D BUILD_SHARED_LIBS=OFF ...
-
SENTRY_BUILD_SHARED_LIBS(Default: ON): By default,sentryis built as a shared library. Setting this option toOFFwill buildsentryas a static library instead. If sentry is used as a subdirectory of another project, the valueBUILD_SHARED_LIBSwill be inherited by default.When using
sentryas a static library, make sure to#define SENTRY_BUILD_STATIC 1before including the sentry header. -
SENTRY_PIC(Default: ON): By default,sentryis built as a position independent library. -
SENTRY_EXPORT_SYMBOLS(Default: ON): By default,sentryexposes all symbols in the dynamic symbol table. You might want to disable it in case the program intends todlopenthird-party shared libraries and avoid symbol collisions. -
SENTRY_BUILD_RUNTIMESTATIC(Default: OFF): Enables linking with the static MSVC runtime. Has no effect if the compiler is not MSVC. -
SENTRY_LINK_PTHREAD(Default: ON): Links platform threads library likepthreadon unix targets. -
SENTRY_BUILD_FORCE32(Default: OFF): Forces cross-compilation from 64-bit host to 32-bit target. Only has an effect on Linux. -
CMAKE_SYSTEM_VERSION(Default: depending on Windows SDK version): Sets up a minimal version of Windows where sentry-native can be guaranteed to run. Possible values:5.1(Windows XP)5.2(Windows XP 64-bit / Server 2003 / Server 2003 R2)6.0(Windows Vista / Server 2008)6.1(Windows 7 / Server 2008 R2)6.2(Windows 8.0 / Server 2012)6.3(Windows 8.1 / Server 2012 R2)10(Windows 10 / Server 2016 / Server 2019)
For Windows versions below than
6.0it is also necessary to use XP toolchain in case of MSVC compiler (pass-T v141_xpto CMake command line). -
SENTRY_TRANSPORT(Default: depending on platform): Sentry can use different http libraries to send reports to the server.- curl: This uses the
curllibrary for HTTP handling. This requires that the development version of the package is available. - winhttp: This uses the
winhttpsystem library, is only supported on Windows and is the default there. - none: Do not build any http transport. This should be used if users want to handle uploads themselves
- curl: This uses the
-
SENTRY_BACKEND(Default: depending on platform): Sentry can use different backends depending on platform.- crashpad: This uses the out-of-process crashpad handler. It is currently only supported on Desktop OSs, and used as the default on Windows, Linux and macOS.
- breakpad: This uses the in-process breakpad handler. It is currently only supported on Desktop OSs.
- inproc: A small in-process handler which is supported on all platforms, and is used as default on Android.
- none: This builds
sentry-nativewithout a backend, so it does not handle crashes at all. It is primarily used for tests.
-
SENTRY_INTEGRATION_QT(Default: OFF): Builds the Qt integration, which turns Qt log messages into breadcrumbs. -
SENTRY_BREAKPAD_SYSTEM(Default: OFF): This instructs the build system to use system-installed breakpad libraries instead of using the in-tree version. -
SENTRY_TRANSPORT_COMPRESSION(Default: OFF): Adds Gzip transport compression. Requireszlib.

SENTRY_FOLDER(Default: not defined): Sets the sentry-native projects folder name for generators which support project hierarchy (like Microsoft Visual Studio). To use this feature you need to enable hierarchy viaUSE_FOLDERSproperty -
CRASHPAD_ENABLE_STACKTRACE(Default: OFF): This enables client-side stackwalking when using the crashpad backend. Stack unwinding will happen on the client's machine and the result will be submitted to Sentry attached to the generated minidump. Note that this feature is still experimental. -
SENTRY_SDK_NAME(Default: sentry.native or sentry.native.android): Sets the SDK name that should be included in the reported events. If you're overriding this, make sure to also define the same value usingtarget_compile_definitions()on your own targets that includesentry.h.
sentry: This is the main library and the only default build target.crashpad_handler: When configured with thecrashpadbackend, this is the out of process crash handler, which will need to be installed along with the projects executable.sentry_test_unit: These are the main unit-tests, which are conveniently built also by the toplevel makefile.sentry_example: This is a small example program highlighting the API, which can be controlled via command-line parameters, and is also used for integration tests.
A minimal working example looks like this. For a more elaborate example see the example.c file which is also used to run sentries integration tests.
sentry_options_t *options = sentry_options_new();
sentry_options_set_dsn(options, "https://YOUR_KEY@oORG_ID.ingest.sentry.io/PROJECT_ID");
sentry_init(options);
// your application code …
sentry_close();Other important configuration options include:
sentry_options_set_database_path: Sentry needs to persist some cache data across application restarts, especially for proper handling of release health sessions. It is recommended to set an explicit absolute path corresponding to the applications cache directory (equivalent toAppData/Localon Windows, andXDG_CACHE_HOMEon Linux). Sentry should be given its own directory which is not shared with other application data, as the SDK will enumerate and possibly delete files in that directory. An example might be$XDG_CACHE_HOME/your-app/sentry. When not set explicitly, sentry will create and use the.sentry-nativedirectory inside of the current working directory.sentry_options_set_handler_path: When using the crashpad backend, sentry will look for acrashpad_handlerexecutable in the same directory as the running executable. It is recommended to set this as an explicit absolute path based on the applications install location.sentry_options_set_release: Some features in sentry, including release health, need to have a release version set. This corresponds to the application’s version and needs to be set explicitly. See Releases for more information.
- The crashpad backend on macOS currently has no support for notifying the crashing
process, and can thus not properly terminate sessions or call the registered
before_sendoron_crashhook. It will also lose any events that have been queued for sending at time of crash. - The Crashpad backend on Windows supports fast-fail crashes, which bypass SEH (Structured
Exception Handling) primarily for security reasons.
sentry-nativeregisters a WER (Windows Error Reporting) module, which signals thecrashpad_handlerto send a minidump when a fast-fail crash occurs But since this process bypasses SEH, the application local exception handler is no longer invoked, which also means that for these kinds of crashes,before_sendandon_crashwill not be invoked before sending the minidump and thus have no effect.
