minilogger
A small logger with backtrace in signal handler
Usage
- build option
Enable the following compile options if you need backtrace
target_compile_options(mytarget PRIVATE -g -ggdb -gdwarf)
target_compile_options(mytarget PRIVATE -rdynamic -funwind-tables)
On ARM, you need an extra environment if you need backtrace
UNW_ARM_UNWIND_METHOD=1 ./mytarget
the output will like:
trace_cpp[12328]: trace_cpp version 1.1
