Programming in Linux environment, it is very important to use the make tool and compile makefile files. Of course, the make tool program in a Windows EnvironmentProgramPersonnel are also useful.
The MAKEFILE file describes the compilation and connection rules of the entire project. These include: Which source files in the project need to be compiled, how to compile, how to create those intermediate files,
This article will briefly analyze the process of Linux kernel compiling zimage. The reader needs to have GNU make, Bash Shell, Python feetThe basics of this, compiler, linker, and more. Although the focus is on the analysis of the construction process of kernel, but also in passing analysis of someOther small points of knowledge.

Make is a very important compilation command in both Linux and UNIX environments. Make or make install is often used for project development and application software installation. With the make tool, we can break down large development projects into multiple modules that are easier to manage. For an application that in

When compiling the Linux kernel, the first thing to do is to modify the makefile file in the top-level directory of the kernel source, change the Arch = $ (subarch) to arch? = arm, and change the cross_compile? = to cross_compile? = arm- LINUX-GCC, or not modified, the arch and Cross_compile values are passed through the command line. Then in the Linux kernel source directory, execute make menuconfig, then what happened? The

This article is based on the U-boot Raspberry Pi 3 Generation configuration Process Analysis, the environment is as follows:Compilation environment: Ubuntu 14.04 LTSCompilation tool: ARM-LINUX-GNUEABI-GCCCode version: U-boot v2016.09Configuration file: Rpi_3_32b_defconfig
U-boot the introduction of Kbuild systems since the v2014.10 version, Makefile's management and organization is much different from previous versions of the Code, and its makefile is more complex. The whole makefile,
In the previous section, we introduced two methods for driver entry into the kernel: module and direct compilation into the kernel, and introduced the module'sOne way to compile: In an independent folder, use makefile with the kernel source code path.
So how to directly compile the driver into the kernel?
What is kernel pruning that we often hear about during kernel porting configuration?
We often execute the make menuconfig command during Linux Kerne

here, I would like to say more about the procedures of compiling some of the norms and methods, in general, whether C, C + +, or PAS, the first to compile the source file into the intermediate code file, under Windows is the. obj file, Unix is the. o file, that is, Object file, this action Do compile (compile). And then a lot of objectfile to the execution file, this action is called Link pas, first to compile the source file into t
adding library files to the executable in the process of compiling the links, the runtime linked files are loaded into the library at the time of the program's execution, which saves the overhead of the system, usually with a suffix name of. So. The libc.so.6 mentioned above is the dynamic library, so you can get GCC to use dynamic libraries by default at compile time. When the link process is complete, GCC can generate the executable file main.
