Question

I’m developing Android audio driver. In case I need to add debug function “LOGD” inside constructor Mutex::Autolock::Autolock(Mutex& mutex), which is defined in "frameworks/base/include/utils/threads.h"

I have already include , but there are still compiling error:

frameworks/base/include/utils/threads.h:244:1: error: macro “LOG” passed 6 arguments, but takes just 1

I guess it’s because the keyword inline blocks external macros, but not for sure.

How can I solve this problem?
Thanks in advance!

Answer 1

Try to define LOGD like so:

#define LOGD(...) __android_log_print(ANDROID_LOG_DEBUG, "my module name", __VA_ARGS__)

Remember you must #include <android/log.h> for this to work.
