QT MinGW32 : bootstrap stacktrace (header only) not showing function names and lines numbers shows only address
Hi Everyone, I am trying to print stack-trace using boost *HEADER-ONLY. *I am using descriptions under Configuration and Build <https://www.boost.org/doc/libs/1_74_0/doc/html/stacktrace/configuration_and_build.html#stacktrace.configuration_and_build.windows_deployment_and_symbol_fi> to compile a simple code using QT MinGW32 I also use the below macros to tune boost: -DBOOST_STACKTRACE_USE_WINDBG -DBOOST_STACKTRACE_USE_ADDR2LINE -DBOOST_STACKTRACE_ADDR2LINE_LOCATION I have no clue why the function names and line numbers are not showing up. Any comment is appreciated. Mike *Below are compile and build instructions:* g++ -g3 -DBOOST_STACKTRACE_USE_WINDBG -DBOOST_STACKTRACE_USE_ADDR2LINE -DBOOST_STACKTRACE_ADDR2LINE_LOCATION=C:\Qt_5_12\Tools\mingw730_32\bin\addr2line.exe -I../../../boost_1_73_0 -c main.cpp -omain.o g++ main.o -o stack_traces.exe -L"C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0\um\x86" -L"C:\temp\libbacktrace" -lkernel32 -luser32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 -lole32 -luuid -lodbc32 -lodbccp32 -lDbgEng *And here is the output ... * 0# 0x00402C75 in stack_traces 1# 0x00401602 in stack_traces 2# 0x004016CE in stack_traces 3# 0x0040138B in stack_traces 4# _BaseThreadInitThunk in KERNEL32 5# _RtlGetAppContainerNamedObjectPath in ntdll 6# _RtlGetAppContainerNamedObjectPath in ntdll 1 + 2 = 3 *The code (main.cpp)* Is fairly simple as below: #include <iostream> #include <boost/stacktrace.hpp> double add(double a, double b){ std::cout << boost::stacktrace::stacktrace(); std::cout << a << " + " << b << " = " << (a+b) << std::endl; return a+b; } int main(){ add(1,2); return 0; }

Hi Mike, this page: https://www.boost.org/doc/libs/develop/doc/html/stacktrace/configuration_and... says that the dbgeng library can only extract symbolic information from 64-bit MinGW executables. It looks like you need to use the 3rd-party libbacktrace library with 32-bit MinGW executables to capture that information. Regards Bill Somerville.
Hi Bill, Thanks to your comment, I got it working for QT MinGW32 (C:\Qt_5_12\Tools\mingw730_32\bin\g++.exe) ! Interestingly enough, I didn't need libdl and I wasn't able to find it under QT-MinGW32 folder either. Though, I was able to see full stack trace even when linking many C and C++ objects in one build. Below is the minimum setup I needed to get things working for the same code discussed earlier. The other interesting experience I had, is that I could see stack trace using -g and -O0 but any higher optimization did not work (at least for me, it only printed the most top function in the call stack) which is more or less acceptable because debug info is only available in debug-enabled compilations. I am just curious, in case I need to create a stack dump / crash report in production (built with optimization level >= 1), how would I be able to achieve that?
