Hi,
I’m trying to integrate Google breakpad with my application in both Linux and Windows. I’ve had no problems with the Linux integration, however I’m having an issue with the breakpad library files for the Windows implementation of my application.
Please note I had already changed the setting “Treat WChar_t As built in Type” and set it to “No(/Zc:wchar_t-)” in Microsoft Visual C++ 2010 Express, Despite this I’m still presented with the same error when compiling my application. I had also tried to set the runtime library to “Multi-threaded Debug DLL, this caused the breakpad client libaries to fail to build.
Below is the qt .pro file:
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = CrashReportSystem
TEMPLATE = app
SOURCES += main.cpp\
mainwindow.cpp \
testcrash.cpp \
fileoperations.cpp \
crashsystemstartup.cpp
HEADERS += mainwindow.h \
callback.h \
testcrash.h \
fileoperations.h \
crashsystemstartup.h
FORMS += mainwindow.ui
BREAKPAD=C:/google-breakpad
INCLUDEPATH +=$${BREAKPAD}/src
QMAKE_LIBDIR += $${BREAKPAD}/src/client/windows/Debug/lib
LIBS += -lcommon
LIBS += -lcrash_generation_client
LIBS += -lexception_handler
What steps will reproduce the problem?
1. Using settings for all 11 projects that make up the breakpad_client Solution in configuration settings: C/C++ Language “Treat WChar_t As built in Type set to “No(/Zc:wchar_t-) and under C/C++ Code Generation Runtime Library “Multi-threaded Debug(/MTd)”
2. Build breakpad_client Solution file in Microsoft Visual C++ Build succeeded on all 11 projects.
3. In Qt build the application LNK2019 error appears.
What is the expected output? What do you see instead?
the creation of the .dmp file from a function that simulates a crash.
What version of the product are you using? On what operating system?
OS: Windows 7 Professional 64 bit edition
To build the breakpad_client libraries
Microsoft Visual C++ 10 Version: 10.0.30319 RTMRel
Microsoft .NET Framework Version 4.0.30319 RTMRel
Active Solution Confederation: Debug
Active Solution platform: Win32
Compiler: Microsoft Visual C++ Compiler 10.0 (x86)
Compiling and Running the application
Qt Creator 2.7.1
based on Qt 4.8.4(32 bit)
Using compiler Microsoft Visual C++ Compiler 10.0 ×86
Please provide any additional information below.
The code below is where the error occurs
std::wstring pathAsStr = (const wchar_t*)pwd.utf16();
static google_breakpad::ExceptionHandler* handler;
handler = new google_breakpad::ExceptionHandler
(
pathAsStr,
/*FilterCallback*/ 0,
dumpCallback,
/*context*/
0,
true
);
