keithpotz/CrashCatch: Cross-Platform, Efficient easy to integrate crash reporting library for modern C++

A cross-platform, efficient, and easy-to-integrate crash-reporting library for modern C++ applications.

CrashCatch is a lightweight, single-header C++ crash-reporting library for generating .dmp and .txt crash logs — complete with stack traces, diagnostics, optional cleanup hooks, and user dialogs.

CrashCatch provides simple and powerful crash diagnostics for C++ applications on Windows and Linux, with macOS support planned. Whether you're building GUI apps, system tools, or CLI utilities, CrashCatch helps you catch and log critical failures with minimal setup.

As of v1.2, CrashCatch supports rich crash context capture and includes optional post-crash upload integration.

✅ Cross-platform: Windows & Linux (macOS coming soon)
🔹 Single-header C++ integration
💥 Exception and signal handling (SIGSEGV, SIGABRT, SIGFPE, etc.)
🧠 .dmp and .txt crash report generation
🧩 onCrash() & onCrashUpload() Hooks – Run cleanup or upload crash artifacts
🔍 Demangled symbols on Linux, symbol resolution on Windows
📋 Self-diagnostics: version, build, architecture, exec path
🧼 Drop-in, no external libraries required
⚙️ Fully configurable output format & location
📁 CMake install + find_package support
🧪 Debug & release builds supported

OS Supported Crash Handling Method Windows ✅ Yes SetUnhandledExceptionFilter + MiniDump Linux ✅ Yes POSIX signals (signal()) + backtrace macOS 🚧 Planned POSIX + Mach exceptions

CrashCatch is 100% header-only.

To integrate:

Copy include/CrashCatch.hpp into your project
Add #include "CrashCatch.hpp" in your code
(Optional) Use CrashCatch::enable() or the CRASHCATCH_AUTO_INIT macro
For Linux inlcude -ldl or -rdynamic for deeper Linux symbole resolution if desired

✅ No build steps.
❌ No .lib, .dll, or .so.
🔒 Just one .hpp file, ready to use.

Copy CrashCatch.hpp into your project and include it:

#include "CrashCatch.hpp"

## QuickStart
### Zero Config (Auto-init)
```cpp
#define CRASHCATCH_AUTO_INIT
#include "CrashCatch.hpp"

int main(){
    int* ptr = nullptr;
    *ptr = 42; // simulated crash
}

#include "CrashCatch.hpp"
int main(){
    CrashCatch::enable(); //Initalizes with default config

    int* ptr = nullptr;
    *ptr = 42; // simulated crash
}

#include "CrashCatch.hpp"

int main(){
    CrashCatch::Config config:
    config.appVersion = "1.0.0";
    config.buildConfig = "Release";
    config.additionalNotes = "This is a test build.";
    config.onCrash = []{
        std::cout << "Cleaning up before crash...\n"/
    };
    config.showCrashDialog = true;

    CrashCatch::initalize(config);

    int* ptr = nullptr;
    *ptr = 42; // simulated crash
}

You can install CrashCatch with:

cmake -Bbuild -DCMAKE_INSTALL_PREFIX=install
cmake --build build --target install
find_package(CrashCatch REQUIRED)
target_link_libraries(MyApp PRIVATE CrashCatch::CrashCatch)

When a crash occurs, CrashCatch generates the following files in the ./crash_dumps/ directory:

crash_YYYY-MM-DD_HH-MM-SS.dmp — Binary MiniDump (viewable in tools like WinDbg)
crash_YYYY-MM-DD_HH-MM-SS.txt — Human-readable crash summary

📋 Example .txt Includes:

CrashCatch provides detailed crash metadata via CrashContext:

struct CrashContext{
  std::string dumpFilePath;
  std::string logFilePath;
  std::string timestamp;
  int singalOrCode;
};

You can use both in onCrash and onCrashUpload
