- Enable
DUK_USE_DEBUG
- Define
DUK_USE_DEBUG_LEVEL=<n>
wheren
is 0 for minimal logs, 1 for verbose logs, and 2 for very verbose logs - Define
DUK_USE_DEBUG_WRITE(level,file,line,func,msg)
to write out log entries; this allows you to fully control where debug logs should go
Example of DUK_USE_DEBUG_WRITE
in manually edited duk_config.h
:
#define DUK_USE_DEBUG_WRITE(level,file,line,func,msg) do { \
fprintf(stderr, "D%ld %s:%d (%s): %s\n", \
(long) (level), (file), (long) (line), (func), (msg));
} while (0)
Same function as an argument to tools/configure.py:
'-DDUK_USE_DEBUG_WRITE(level,file,line,func,msg)=do {fprintf(stderr, "D%ld %s:%ld (%s): %s\n", (long) (level), (file), (long) (line), (func), (msg));} while(0)'
