<1>. Days Without makefile  

[Previous] introduced the makefile writing rules. The first title is "Days Without makefile". If you receive a reply from zhuangzhuang1988, a netizen from [blog], you can use automake to automatically generate makefile. If you have installed a program from the source code in linux, the general process is as follows:

./Configure; make install

Next we will try to generate this release version, which mainly uses tools such as aclocal and automake.

 

1. Now let's assume that the source code of the program has been compiled. Here is main. c.

Xuqiang @ ubuntu :~ /Automake/helloworld $ ls

Main. cxuqiang @ ubuntu :~ /Automake/helloworld $ cat main. c # include <stdio. h> int main () {printf ("hello linux world! "); Return 0 ;}

2. Run autoscan. The autoscan. log and configure. scan files are generated.

Xuqiang @ ubuntu :~ /Automake/helloworld $ autoscan

Xuqiang @ ubuntu :~ /Automake/helloworld $ lsautoscan. log configure. scan main. c

3. We use configure. scan as the template of the configure. in file for use by aclocal. First, change configure. scan to configure. in.

Xuqiang @ ubuntu :~ /Automake/helloworld $ mv configure. scan configure. in

Modify configure. in:

Xuqiang @ ubuntu :~ /Automake/helloworld $ vim configure. in

Xuqiang @ ubuntu :~ /Automake/helloworld $ cat configure. in #-*-Autoconf-*-# Process this file with autoconf to produce a configure script. AC_PREREQ ([2.63]) AC_INIT ([helloauto], [1.0], [xuqiang@gmail.com]) AC_CONFIG_SRCDIR ([main. c]) # comment this line, no use # AC_CONFIG_HEADERS ([config. h]) # Checks for programs. AC_PROG_CC # Checks for libraries. # Checks for header files. # Checks for typedefs, structures, and compiler c Haracteristics. # Checks for library functions. # init automakeAM_INIT_AUTOMAKE (helloauto, 1.0) # write out the makefileAC_OUTPUT (Makefile) 4. execute the aclocal command to generate aclocal. m4 autom4te. cache two files: xuqiang @ ubuntu :~ /Automake/helloworld $ aclocalxuqiang @ ubuntu :~ /Automake/helloworld $ lsaclocal. m4 autom4te. cache autoscan. log configure. in main. c

5. Run the autoconf command to generate the configure file.

Xuqiang @ ubuntu :~ /Automake/helloworld $ autoconf

Xuqiang @ ubuntu :~ /Automake/helloworld $ lsaclocal. m4 autom4te. cache autoscan. log configure. in main. c6. create the Makefile. am file, which is the dependent file of automake.

Xuqiang @ ubuntu :~ /Automake/helloworld $ vim Makefile. am

Xuqiang @ ubuntu :~ /Automake/helloworld $ cat Makefile. amAUTOMAKE_OPTIONS = foreignbin_PROGRAMS = helloautohelloauto_SOURCES = main. c7. run the automake command to add the required scripts, such as the INSTALL file, to the source file directory. Xuqiang @ ubuntu :~ /Automake/helloworld $ automake -- add-missingMakefile.am: installing '. /INSTALL 'makefile. am: required file '. /NEWS 'not foundMakefile. am: required file '. /README 'not foundMakefile. am: required file '. /AUTHORS 'not foundMakefile. am: required file '. /ChangeLog 'not foundMakefile. am: installing '. /COPYING 'using GNU General Public License v3 fileMakefile. am: Consider adding the COPYING file to the ver Sion control systemMakefile. am: for your code, to avoid questions about which license your project uses. xuqiang @ ubuntu :~ /Automake/helloworld $ lsaclocal. m4 autoscan. log config. status configure. in INSTALL Makefile. amautom4te. cache config. log configure COPYING main. c Makefile. in

8. Test the file generated above.

Xuqiang @ ubuntu :~ /Automake/helloworld $./configure

By using these tools, only a few simple files can be written to generate Makefile and compile the source code.
