跟我一起,10分鐘搞懂configure檔案自動生成Makefile檔案簡單步驟.


1.準備原始碼 hello.c func1.c func1.h func2.c func2.c


hello.c:
#include <func1.h>


void main() {
        m_printf("hello world!\n");
}


func1.c:
#include <func1.h>


void m_printf(const char* str) {
    m_m_printf(str);
}


func2.c:
#include <func2.h>


void m_m_printf(const char* str) {
        printf(str);
}


func1.h
#ifndef func1_h
#define func1_h


#include <func2.h>


void m_printf(const char* str);


#endif


func2.h
#ifndef func2_h
#define func2_h


#include <stdio.h>


void m_m_printf(const char* str);


#endif

2.原始碼目錄執行autoscan生成configure.scan, 移動configure.scan至configure.ac,編寫configure.ac

configure.ac:
#                                               -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.


AC_PREREQ([2.69])
AC_INIT([hello], [1.0], [[email protected]])
AM_INIT_AUTOMAKE
AC_CONFIG_HEADERS([config.h])


# Checks for programs.
AC_PROG_CC


# Checks for libraries.


# Checks for header files.


# Checks for typedefs, structures, and compiler characteristics.


# Checks for library functions.


AC_OUTPUT([Makefile])


3.執行aclocal生成m4檔案


4.執行autoheader生成config.h.in

5.編寫Makefile.am

Makefile.am:
noinst_PROGRAMS=hello


hello_SOURCES=hello.c


hello_LDADD=$(top_srcdir)/func1.o \
        $(top_srcdir)/func2.o


hello_LDFLAGS=-I$(top_srcdir)


6.執行automake
如果出現錯誤
error: required file './compile' not found
error: required file './install-sh' not found
error: required file './missing' not found
error: required file './INSTALL' not found
執行 automake --add-missing
如果出現錯誤
Makefile.am: error: required file './NEWS' not found
Makefile.am: error: required file './README' not found
Makefile.am: error: required file './AUTHORS' not found
Makefile.am: error: required file './ChangeLog' not found
Makefile.am: installing './COPYING' using GNU General Public License v3 fil
執行touch NEWS README ChangeLog AUTHORS
然後在執行automake -a



7.執行autoconf生成configure檔案


8. ./configure 生成Makefile


9.測試Makefile
執行make
