Hi all, I'm building a custom image with mx6dl using branch 4.1.15-1.0.0_ga with qt5.5.1, gdb 7.9.1 and i have a problem to debug qt applications. When i used the meta-toolchain-qt5 and try to launch my application i have the following message at start : >*running,thread-id="all" dNOTE: INFERIOR STILL RUNNING IN STATE InferiorRunOk. >~"\nProgram received signal " >~"SIGSEGV, Segmentation fault.\n" >~"0x47559e24 in ?? ()\n" >*stopped,reason="signal-received",signal-name="SIGSEGV",signal-meaning="Segmentation fault",frame={addr="0x47559e24",func="??",args=[]},thread-id="1",stopped-threads="all",core="0" dNOTE: INFERIOR SPONTANEOUS STOP sStopped. I try to backtrace the problem and i can't have informations. <765bt >&"bt\n" >~"#-1 0x47559e24 in ?? ()\n" >~"Backtrace stopped: Cannot access memory at address 0x324e5a56\n" >765^done When i set breakpoint in my main program at the first line the program has the same behavior. I use qt-creator to debug and i try without but it's the same problem ,could someone help me? Thanks for all, Re: Nouveau format signature électronique Best Regards Julien CARBONNIER
