enabling logs in android_reboot.c

[sudhir]

Hi

I want to debug android_reboot.c file by putting logs in system/core/libcutils/android_reboot.c

I have included <cutils/log.h> and used LOGD to log messages.

But while building i am always getting the following link error.

 undefined reference to '__android_log_print

I am not sure how to include the liblog in system/core/libcutils/ Android.mk .

Could anyone please help me in resolving this problem.

Thanks

Sudhir

You should have something like -llog in the linker command that ends
up executed.

Fastest solution is probably to look for examples - ie grep -r the
tree for existing invocations of the log function in source, and then
check the makefile associated with that source.

constructor cached in sConstructorMap, so when mContex changed

Try to compile only libcutils project and sync with Android device.

The reason why you could not compile libcutils with included cutils/log.h and call to LOGD is because __android_log_print is included in liblog.so, but liblog.so is compiled after the compileation of libcutils.
