Hi.
I use this
in the PRO file
windows {
LIBS+=-ldbghelp#beabletoprintthestacktrace
}
then
intmain(intargc,char*argv[])
{
//0.somepreliminarystuff
//printstacktraceuponSegmentationFault
signal(SIGSEGV,os_signal_print_stack_trace);/*segmentviolation*/ // you could
do the same on other OS signals. E.g.
//signal(SIGINT,os_signal_print_stack_trace);/*interrupt*/
//signal(SIGILL,os_signal_print_stack_trace);/*illegalinstruction-invalidfunctionimage*/
//signal(SIGFPE,os_signal_print_stack_trace);/*floatingpointexception*/
... }
and then
#if(defined(__OS__MACOSX__)||defined(__OS__LINUX__))
#include<execinfo.h>
#include<signal.h>
#include<stdlib.h>
voidos_signal_print_stack_trace(intsig)
{
void*array[10];
size_tsize;
//getvoid*'sforallentriesonthestack
size=backtrace(array,10);
//printoutalltheframestostderr
fprintf(stderr,"Error:signal%d:\n",sig);
backtrace_symbols_fd(array,size,2);
system_crash_event();
log_fatal("["__OS__":"__RUNTIME__":"__LIB_BUILD_TYPE__"]:programfoundanunrecoverableerrorandmustquit");
exit(-10);
}
#elifdefined(__OS__WINDOWS__)
#include<DbgHelp.h>
#include<sstream>
voidos_signal_print_stack_trace(intsig)
{
//AllDbgHelpfunctions,suchasthisone,aresinglethreaded.Therefore,callsfrommorethan

Hello,
Question to Windows gurus - what is the best way to get stack trace
after crash? Say Qt/QML application runs in QA environment, not
development. MacOS creates log with the stack trace, I am looking to
something similar on Windows.

Boris Ralchenko.
