dev_notes's Issues

I caught the dump file on MacOS (M1), but when I used minidump_stackwalk tool analysis failed, please help me analyze the reasons.

License of code

Hello Jaco,

Thank you very much for the guides you have posted. "Using Google Breakpad with Qt" is especially useful to me, and I was wondering if I could use the code from there. Under what license is this code? It would really help me if I could use those snippets in my commercial project.

Compile errors with Qt 5.5.1 and latest google breakpad

I followed the blog instructions exactly and ran into problems when I tried to compile on Ubuntu 14.04 using QT Creator 3.5.1 with QT 5.5.1 and gcc.
There were 20 errors total: 12 in crash_handler.cpp, 1 in exception_handler.cpp, 5 in minidump_writer.cc, and 2 in linux_ptrace_dumper.cc.

There were some multiple definition errors like:
.../crashhandler/crash_handler.cpp:46: error: multiple definition of Breakpad::CrashHandlerPrivate::pHandler' In functionQByteArray::length() const' in crash_handler.o

.../crashhandler/crash_handler.cpp:46: error: multiple definition of Breakpad::CrashHandlerPrivate::bReportCrashesToSystem' in functionload': in crash_handler.o

There were also several undefined reference errors in the google_breakpad code:
.../crashhandler/src/client/linux/minidump_writer/minidump_writer.cc:328: error: undefined reference to `google_breakpad::UContextReader::GetStackPointer(ucontext const*)'

Any idea what's causing the errors?

about QCA on Windows

Hi, I read your notes about compiling QCA on Windows.

Did you try to use libqca in a project? Because I built it successfully with MinGW toolchain, but I can't use it in any project. Always undefined reference errors. Just want to make sure whether it's my problem.
