Hi,
I am attempting to generate stacktraces in a thread using the
system calls backtrace and backtrace_symbols
Code:
#define NUM_STACKFRAMES 50
void *arr[NUM_STACKFRAMES];
int nSize = backtrace(arr, NUM_STACKFRAMES);
char **sym = backtrace_symbols(arr, nSize);
char nl = '\n';
int ii;
for (ii = 0; ii < nSize; ii++) {
SENDTOLOGS(alog,apstklog,sym[ii]);
SENDTOLOGS(alog,apstklog, &nl);
}
free(sym);
return ii;
backtrace_symbols is able to find function names in the
library that has the stacktracing code but is unable to find the
function names in any of our other libraries - backtrace has returned the
correct address.
I used the the flags -rdynamic and -fno-omit-frame-pointer to build
our libraries.
Any suggestions for what I might try ?
Code:
lib15.so(_ZN6UIQCtl14ValidateOptionEP11IConnectionP9an_option15an_option_scopePcP15an_option_value+0xb6) [0x2aab5dd9a8]
lib15.so(_ZN20saint_iqthresholdctl14ValidateOptionEP11IConnectionP9an_option15an_option_scopePcP15an_option_value+0x4d) [0x2aab5db13f]
lib16_r.so [0x2a958de1fe]
lib16_r.so [0x2a958df77b]
