As a program developer in Linux, you must have encountered Makefile. It is really convenient to compile your own programs by using the make command. Generally, you write a simple Makefile manually. If you want to compile a Linux Makefile that complies with the Free Software conventions, it is not that easy. In this article, we will introduce how to use the autoco

Say the "D" prefix (which means details), which calls the following three parameters. $ (Origin): tells you where this variable comes from, file represents the document, environment represents the environment variable, and environment Override,command line,override,automatic, and so on. $ (value): The way this variable is typed is not expanded. such as the Foo variable
With the development of the mobile Internet, mobile development is becoming more and more popular. Currently, Android is the most popular. No need to mention Android. Android has been sought after by many people since its open source. Of course, one person is pursuing it because it was developed by Google. For a programPersonnel, a system value is not worth the pursuit of code to speak. I am not going to analyze the android code here, but the android makefil
Overview Packed from: http://www.cnblogs.com/liangxiaxu/archive/2012/07/31/2617384.html What is makefile? Maybe many winodws programmers do not know this, because the windows ide has done this job for you, But I think makefile should be understood as a good and professional programmer.

Write command The command lines in each rule are the same as those in the operating system shell. Make will execute the command one by one in sequence. Each Command must start with a [Tab] key, unless the command is followed by a semicolon after the dependency rule. Spaces or blank lines between command lines are ignored. However, if the space or blank line starts with the tab key, make considers it an empty command. We may use different shells in UNIX, but the make command is interpreted and ex

I. Introduction to makefile Makefile is used for automatic compilation and linking. A project consists of many files. Changes to each file will lead to re-linking of the project, but not all files need to be re-compiled, the makefile records the file information. During make, it determines which files need to be re-compiled during the link. The purpose of
I don't know. As a complete Windows platform under the less professional software engineering students, see the "Accelerated C + +" source code, the first reaction is: Oh! I should use make to generate project files. Then I happily use AOL to start searching for relevant information.And then the egg! I must have been possessed by some strange creature. I should import files directly with VS Create Project. Then ... ctrl+f5. How perfect.But...... Following:"T

Use automake and Autoconf to generate makefile People who have written programs on UNIX, especially those who use C to develop programs, generally encounter makefile. It is really convenient to use make to develop and compile programs, however, writing a makefile is not that easy. GNU make's hundreds of pages of files scared many people. Of course, there are many
the use of unfamiliar, less), the solution is: to do a summary. Take notes, write more code often.2.2.6.3, while loop and case language and reference combination (1) The break keyword in the shell and the C language have the same meaning (all jumps out) but the usage is different. Because the break in the shell is only used for looping out. So when a case statement is embedded in the while, the break in the box jumps out of the outermost loop, not out of the case statement. (2) The

Preface If you have installed software from the source code, you must be familiar with./configure make install. But what happened behind the scenes in every step of the process? This article will show you how to find out. An in-depth understanding of this process will help you develop your own tricks on the basis of LFS. However, it should be noted that the makefile and make explanations in this article are quite short-sighted and superficial, but it

In Linux or UNIX environments, For small programs that contain only a few source code files (such as hello.c), you can manually type the GCC command to compile the source code files one by one; however, in large project development, it may involve dozens of to hundreds of source files, compiled by manual typing, it is very inconvenient, and once changed the source code, especially the header file occurred modification, manual compilation and maintenance of the workload is quite large, and error-
