Specifically, it replaces the implementations of the +.BR liberror_save_backtrace (3) +and +.BR liberror_print_backtrace (3) +functions with implementations that actually save and print +the backtrace. There is no header files associated with the +.B liberror-backtrace +library it is simply used by linking. If +.B liberror +is dynamically linked, +.B liberror-backtrace shall +be linked with +.I -lerror-backtrace -ldw -lunwind +and +.I -lerror-backtrace +shall be specified before +.IR -lerror . +If +.B liberror +is statically linked, +.B liberror-backtrace shall +be linked with +.I -Wl,--whole-archive -lerror-backtrace -Wl,--no-whole-archive -ldw -lunwind +and it does not matter where whether +.I -lerror-backtrace +is specified before or after +.IR -lerror . +Thus, a library using +.I -lerror +can always be linked with +.I -Wl,--whole-archive -lerror-backtrace -Wl,--no-whole-archive -ldw -lunwind -lerror +for +.B liberror +with backtrace support. Alternatively, if +.B liberror +is dynamically linked, +.B liberror-backtrace +can be preloaded with the +.I LD_PRELOAD +environment variable. +.SH EXAMPLES +None. +.SH APPLICATION USAGE +None. +.SH RATIONALE +None. +.SH FUTURE DIRECTIONS +None. +.SH NOTES +None. +.SH SEE ALSO +.BR liberror (7) |
