Next we will try to use the GCC command line to compile it, so as to understand the details of the android compiling environment. The android compilation environment provides the "showcommands" option to display the compilation command line. We can open this option to view some

An important step in embedded development is to build your own cross-compilation environment, that is, compile and generate the Execution code on the target machine on the host machine. For example, on the i386 hostFor Linux operating systems, embedded systems such as Linux are installed on the arm board. To develop applications on the board, edit and compile on the host machine (i386, link to generate the target code and then download it to the target machine for execution. The compiler needs t

fully support POSIX standards, such as C ++ exceptions, wide charOther toolchains cannot be used to compile androidI personally think that the speed of the system is not closely related to glibc. The slowness of Android is caused by the platform rather than glibc,Therefore, it is unwise for Android to replace glibc with Bionic. Therefore, it is better to develop its own compiler toolchain and bionic to focus on platform development.Is it to bypass GP

) Suppose you have an arm cross-compilation tool (cross -- compiling toolchain) in/usr/local/ARM/3.3.2/, You have to output it to path: $ Export Path =/usr/local/ARM/3.3.2/bin: $ path Check the kernel documentation (in documentation/changes) for the minimum tool version requirements.Compile and install the kernel 1. $ make // if you have modified makefile Or 1'. $ Make arch = arm cross_compile = arm-Linux- 2.

Besides programming with Java, We're also able to do native programming with C or C ++ on Android platform. To do so, we need a cross compiler target on ARM processor for our working platform (Windows or Linux ). so I downloaded sourcery g ++ lite 2009q3-68 for ARM Eabi, the tool chain for arm. if you're careful enough, You wowould have noticed my mistake which took me a day to figure out. unfortunately, I downloaded the wrong tool chain. the correct one is sourcery g ++ lite 2009q3-67 for arm g

target itself (the so-called self-hosted development ). however, due to various constraints (RAM, CPU, connectivity, etc .), it is rarely practical to develop any real-world application on the targetDirectly. As a result, a cross-compilation environment is normally used instead and in this guide we will only consider this approach. Note also that this guide is not an introduction to developing C ++ applications for mobile/embedded systems. in particle, it assumes that you are familiar with the
