Kandao QtBreakpad Demo

1. This a demo to handle c++ crash with google breakpad and launch a Qt app to send crash log back to server.
2. Most of the code are extracted from Qt Creator project.
3. The Demo includes a QtBreakpadDemo which crashes, launching the QtCrashHandler afterwards.

---

Dependency

1. Qt5
2. breakpad's source files are used directly. No need to compile breakpad

---

Build

0. clone with submodules （use recursive)

>> git clone https://github.com/KandaoVR/qt-breakpad.git --recursive

1. Windows

• use CMake-Gui to generate Visual Studio Solution
• Build ALL

2. Mac

>> mkdir build
>> cd build
>> cmake -DCMAKE_PREFIX_PATH=/path-to-qt-clang/ -DCMAKE_INSTALL_RPATH_USE_LINK_PATH="ON" ../
>> make -j8 install

>> cd install/Demo
>> ./QtBreakpadDemo

• cmake command example:

    cmake -DCMAKE_PREFIX_PATH=~/Qt/5.11.1/clang_64/ -DCMAKE_INSTALL_RPATH_USE_LINK_PATH="ON" ../
  

• reference: https://stackoverflow.com/questions/47697761/cmake-run-time-error-dyld-library-not-loaded-for-dynamically-linked-resource

OSX Bundle

• If the main app is built with bundle, i.e. add MACOSX_BUNDLE to add_executable. For example:

    add_executable(QtBreakpadDemo MACOSX_BUNDLE ${SOURCES} ${BREAKPAD_SRCS} ${ICON_FILE} ${QM_FILES})
  

• The binary version of QtCrashHandler should be copied to QtBreakpad.app/Contents/MaxOS/, so that the inner binary QtBreakpad is able to call QtCrashHandler during crashing.

3. Linux

• Should be working. lol
• Pull requests are welcomed!
