　　Now the IDE environment is mostly highly integrated, only need to press a button to complete the compilation-assembly-link work, but in the process of embedded development, need to write according to the actual needs of the individual needs, which need to master the makefile.　　The convenience of the advanced IDE is based on makefile, and makefile is actually a

The variable defined in makefile, like a macro in the C + + language, represents a text string that, when executed in makefile, automatically expands to the original mode as it is used. It differs from C/s + + in that you can change its value in makefile. In makefile, variables can be used in "targets", "dependent targ

Please write a makefile at the same time compile, link the following two programs: MAIN1.C: #include int main (void) { printf ("main1\n"); } MAIN2.C: #include int main (void) { printf ("main2\n"); } "Analysis": Here you need to generate two executables main1 and main2 (two destinations). Since makefile can only have one target, it is possible to construct an ultimate goal all with no rules and rely on

Makefile is used for compiling the entire project under Linux, which is very important for the compiler of C/s + + language under Linux. This paper takes the practical C source program as an example, introduces how to use makefile to compile the C language project under Linux, which provides a reference for the development of related work. One, what is makefile

The usage variable of Makefile in linux programming-Linux general technology-Linux technology and application information. For details, see the following. How variables work: 1. The variable is a text string; 2. When Makefile is executed, the variables are automatically displayed in the original mode where they are used; 3. variables can be used in: "target", "dependency target", "command", or other parts o

2, the second partThe usage,targets,savetarget,savedefines here are pseudo-targets.Unlike all, these pseudo-targets are not executed unless these targets are explicitly specified.Here are two targets savetarget,savedefines we mentioned before.The command make target=esb savetarget can save the default TARGET to Makefile.target.by command make target=esb defines=mytrace,myvalue=4711 savedefines can save the default defines to makefile.$ (TARGET). The

7. conditional statements for makefile A conditional statement can execute or ignore some scripts in the MAKEFILE file based on the value of the variable. A condition statement can compare a variable with the value of another variable or a variable with a String constant. The condition statement is used to control the makefile part actually seen by make. It cann

creates the makefile. In structure defined in makefile. am.The configure script then converts the generated makefile. In file to makefile. If some special macros are defined in Configure. AC, such as ac_prog_libtool, it will call libtoolize; otherwise, it will generate config. Guess and config. sub.

Mao learned how to install and uninstall the driver module. During this process, Mao found that many Kconfig and Makefile files are in the kernel directory, but Mao does not know why these files are needed, what are these files used. Next we will study the role of these documents with Tao

mytool2 print % s \ n", print_str );}Of course, because this program is very short, we can compile it like this.Gcc-C main. cGcc-C mytool1.cGcc-C mytool2.cGcc-O main. O mytool1.o mytool2.oIn this way, we can also generate the main program, which is also very troublesome from time to time. However, if one day we modified one of the files (for example, mytool1.c), would we have to re-enter the above command? You may say that this is easy to solve. I wrote a shell script and asked her to help me c

Vi. Multi-Objective There can be more than one target in the makefile rule, which supports multiple targets. It is possible that multiple targets depend on one file at the same time, and the generated commands are similar. So we can combine them. Of course, the execution command for Generating Rules for multiple targets is the same, which may cause us trouble, fortunately, we can use an automation variable "$ @" (the automation variable will be descri

In shell, you can use export to modify the environment variables of the current process. For example,Export Path =.: $ pathYou can add the current path to the executable file search path, so that you do not need to press "./excutable" to execute the excutable in the current path. You only need to type "excutable. Make can execute shell commands, including export. The Make syntax also contains the export operator. In this way, in the same makefile, the

vi. Multi-Objective There can be more than one goal in the makefile rule, which supports multiple targets, and it is possible that many of our goals depend on a single file at the same time, and that the commands generated are broadly similar. So we can combine it. Of course, the execution commands for multiple target generation rules are the same, this may be a problem for us, but the good news is that we can use an Automation variable "$@" (about th

Chen Hao's masterpiece-"Write Makefile with me"-general Linux technology-Linux programming and kernel information. The following is a detailed description. Have you learned today? This is a good getting started Makefile tutorial. Thank you for providing us with such good information !! The previous link was maliciously deleted by a moderator. Now, the downloa

This article teaches you how to use autoconf, automake, etc. to make a software published in Source code form (. tar.gz) and to use custom parameters when executing configure.I. Overview and BASIC knowledgeUnder Linux you get a package published in source code (typically. tar.gz or. tar.bz2 format), and we can compile the installation with./confiugure, make, made install, which is running. Configure can also be used to add different parameters according to their own needs (available./configure--

First: Makefile Document Preparation | 1. The first letter is capitalized and the rest is lowercase. | 2.Makefile is related to the compilation of the whole project. | 3. Can execute the operating system command. | 4. In fact, the essence of makefile is to define the problem of dependency between documents. | 5. The first letter is capitalized and the rest is low

Writing rules———— The rule contains two parts, one is a dependency, and one is the method of generating the target. In Makefile, the order of the rules is important because there should be only one final goal in Makefile, and all other goals are associated with this goal, so make sure you know what your ultimate goal is. In general, there may be a lot of goals defined in
