how to invoke a third party library file (. So) in the Android NDK1. Create a prebuilt subdirectory under the Project/jni directory (directory name customizable).2. Put the third party. So in the prebuilt and create the ANDROID.MK, as follows:Local_path: = $ (call My-dir)Include $ (clear_vars)Local_module: = xxxLocal_src_files: = libxxx.soInclude $ (prebuilt_shared_library)3. Add in Project/jni/android.mkLocal_shared_libraries: = xxx4. In the final pa

The first part: the compilation processFirst understand the Linux C code compilation process, c code compilation, generally divided into four stages, including: Pre-compilation, compilation, compilation and linking, the four phases of division isPre-compilation phase:Compile phase:Assembly phase:Link stage:Part Two: definition of dynamic link library and static link libraryThe third part: the difference between the dynamic link

ObjectiveThis is a series of articles made up of "compiling a glib library to run on Android" and 4 other articles, which are listed in the "Compiling dependent Libraries" section of the 4 articles. Since the glib library relies on other third-party libraries, it is necessary to cross-compile the dependent third-party libraries onto the Android platform to successfully compile the glib

Link Library and address irrelevant code, Link Library address [Static connection and dynamic link library] [Static link]---> Static library: Link to the source program and load it to the virtual memory[Dynamic Link]---> Shared Library:For each database, the operating system allocates a specific virtual memory address.

Both static and dynamic libraries share code. Static link library (LIB ):Complete all assembly work before the program execution and generate an executable target file (exe file ). Static databases have two features: The executable file generated after the Link contains the code of all functions to be called, so it occupies a large disk space. If multiple (calling the same library function)

Preface Dear reader, Welcome to "go beyond the C ++ standard library: boost library Guide". This book is for you if you are interested in generic programming, library design, and C ++ standard libraries. This book is intended for medium and high level C ++ programmers. Some basic concepts of C ++ are hardly involved in this book. As the title implies, this book f

When it comes to concurrency, we think of multithreading and multi-process.Does it use multiple processes or multithreading? It depends on the situation. Our procedures are generally divided into:1) consume the network (a large part of the time is in the network interaction);2) CPU consumption (full use of multicore)In the first case, most of the time is occupied by the network delay, so the use of multithreading and multi-process are similar.In the second case, the length of time is determined
