It looks like in one of last c++ boost version appeared library to provide exactly what You want, probably the code would be multiplatform. It is boost::stacktrace, which You can use like as in boost sample:
#include <filesystem>
#include <sstream>
#include <fstream>
#include <signal.h> // ::signal, ::raise
#include <boost/stacktrace.hpp>
const char* backtraceFileName = "./backtraceFile.dump";
void signalHandler(int)
{
::signal(SIGSEGV, SIG_DFL);
::signal(SIGABRT, SIG_DFL);
boost::stacktrace::safe_dump_to(backtraceFileName);
::raise(SIGABRT);
}
void sendReport()
{
if (std::filesystem::exists(backtraceFileName))
{
std::ifstream file(backtraceFileName);
auto st = boost::stacktrace::stacktrace::from_dump(file);
std::ostringstream backtraceStream;
backtraceStream << st << std::endl;
// sending the code from st
file.close();
std::filesystem::remove(backtraceFileName);
}
}
int main()
{
::signal(SIGSEGV, signalHandler);
::signal(SIGABRT, signalHandler);
sendReport();
// ... rest of code
}
In Linux You compile the code above:
g++ --std=c++17 file.cpp -lstdc++fs -lboost_stacktrace_backtrace -ldl -lbacktrace
Example backtrace copied from boost documentation:
0# bar(int) at /path/to/source/file.cpp:70
1# bar(int) at /path/to/source/file.cpp:70
2# bar(int) at /path/to/source/file.cpp:70
3# bar(int) at /path/to/source/file.cpp:70
4# main at /path/to/main.cpp:93
5# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6
6# _start
