When compiling the Hal layer of Android 4.0, the following error message is displayed:

Root @ brantyou-Ubuntu :~ /Workspace/android-4.0.4_r1.2 # Mmm Hardware/libhardware/modules/Hello/====================== ========================== relplatform_version = 4.0.4target _ Product = fulltarget_build_variant = engtarget_build_type = target_arch = Signature = armv7-aHOST_ARCH = x86host_ OS = linuxhost_build_type = releasebuild_id = imm76i ================================ ========== Make: Enter the directory '/home/brantyou/workspace/android-4.0.4_r1.2' Make: *** no rule can be created for "Out/target/product/generic/obj/shared_libraries/hello. default_intermediates/linked/hello. default. so "target" out/target/product/generic/obj/lib/liblog. so ".

So libm. javascrtend_so.o libdl. So libstdc ++. So

As you can see, there is no liblog. So library file under the corresponding directory.

Through searching, we found that liblog is located in the system/CORE/folder under the android source code directory, and its code is found below.

Here, we need to compile and generate the library file through the command:

make liblog

For example:

The last sentence indicates that the database has been generated. This solves the problem.

 

 

I am new to Android underlying development and have encountered many problems. I can't find many questions online, so I have to come by myself ~~
