- Subject: gdb "bad physname", no c++ symbols or stack
i have built a program consisting of mostly c++
sources with gcc.
when i try to debug it with gdb, almost none of the
functions or other symbols can be referenced for
breakpointing or otherwise.
i can not get a list of functions.
i can not get listing information for any c++ source.
i was able to put a break point in one of the c
sources.
when the program stopped there, the stack trace
effectively disappeared when it ascended up into the
c++ routines.
there is a consistent complaint to many of these
commands as follows:
bad physname
_ZNSt15const_mem_fun_tIv11packagemetaEC1EMS0_KFvvE
what might be wrong?
some debugging session output is shown below.
