Makefile Handouts (1)--makefile Basics (Overview)

Recently in learning Linux under the C programming, bought a called "Linux environment in the C Programming Guide" read to makefile more and more confused, may be my understanding can not. So Google came to the following article. Plain and easy to understand. Then post it for easy learning. PostScript, read this article and the "Linux environment in the C Programming Guide," The makefile chapter of the asto

Gnu makefile detailed tutorial-2: Makefile Overview

I. What is in Makefile? Makefile mainly contains five things:Explicit rules,Concealed rules,Variable definition,File indicationAndNote. 1,Explicit rules: Explicit rules demonstrate how to generate one or more target files. This is clearly pointed out by Makefile writers that the files to be generated, the dependent files of the files, and the generated commands.

program into modules, which were decomposed into different files. When one of these parts changes, because the other file's target source file already exists, so the compiler does not need to compile all the code to generate a new executable file, and only need to compile the changed source files, and then connect all the target files on it, which is very important in the large project development, This can reduce the compilation time from several hours to a few minutes. That's what make can do

The file name order for make lookup is: "Gnumakefile", "Makefile", "Makefile"

By default, make will look for the makefile file to read and execute in the file name order in the working directory (the directory where the make is executed), looking for the file name in the following order: "Gnumakefile", "Makefile", "makefile".Usually you should use "makefile" or "

Lesson 3 make Makefile (I) and make makefile

Lesson 3 make Makefile (I) and make makefilePreface: The previous course explains the gcc compilation process to its practice. You can see that some of these steps can simplify compilation, however, due to the large number of parameters and the large number of files in the project, errors may occur, or even a lot of time is wasted on compilation. Therefore, this tool is also available in the linux system: makefile.Principle: In fact, the essence of

Automatic build Makefile (1)--c/c++ compilation process &makefile rules Introduction

Objective:You don't need to edit a slightly obscure makefile file when you build a C + + program using VS on Windows, and for starters, they don't even realize it's there. VS is to automatically generate makefile files and build the project. There is no denying that Visual Studio is an all-purpose IDE, it helps developers do a lot of work, but also reduce the threshold of the C + +, the significance is very

Makefile condition judgment ---------- [Badboy], makefile condition badboy Conditional judgment allows make to select different execution branches based on different running conditions. A conditional expression can be used to compare the value of a variable or a constant. I. Example In the following example, determine whether the $ (CC) variable is "gcc". If yes, use the GNU function to compile the target.

Makefile comprehension (4) [compile makefile in the Android. mk analysis module]

Finally, C ++ code porting was introduced to bootloader. The only achievement was familiarity with makefile. Some factory companies could not afford to be hurt. Every time they had to do something to meet the needs of factory-side testing, in order to be able to meet the requirements of the factory for testing in Boot, after discussion with the chip company, only C ++ can be obtained to boot, it is really a second decision that boot will eventually ac

Makefile Introduction and how Makefile Works

When the make command executes, a makefile file is required to tell the make command how to compile and link the program.First, we use an example to illustrate Makefile's writing rules. In order to give everyone a perceptual knowledge. This example comes from the GNU Make manual, in which we have 8 C files, and 3 header files, and we're going to write a makefile to show how the Make command compiles and lin
