第二讲
perl 加载c/c++的库
先通过h2xs 创建一个新的工程
h2xs -A -n two_test
进入目录
cd two_test
创建一个mylib文件夹，存放静态库
mkdir mylib
c程序头文件chen.h
#include<stdio.h> void chen(char *);
c程序代码chen.c
#include "chen.h" void chen(char * name){ printf("input string is : %s\n", name); }
编译静态库
gcc -c chen.c ar -r libchen.a chen.o
将libchen.a静态库与chen.h头文件拷贝到two_test/mylib
cp libchen.a two_test/mylib/
cp chen.h two_test/mylib
修改perl 生成makefile 的脚本Makefile.PL
use 5.014002; use ExtUtils::MakeMaker; # See lib/ExtUtils/MakeMaker.pm for details of how to influence # the contents of the Makefile that is written. WriteMakefile( NAME => ‘two_test‘, VERSION_FROM => ‘lib/two_test.pm‘, # finds $VERSION PREREQ_PM => {}, # e.g., Module::Name => 1.1 ($] >= 5.005 ? ## Add these new keywords supported since 5.005 (ABSTRACT_FROM => ‘lib/two_test.pm‘, # retrieve abstract from module AUTHOR => ‘root <root@>‘) : ()), LIBS => [‘‘], # e.g., ‘-lm‘ DEFINE => ‘‘, # e.g., ‘-DHAVE_SOMETHING‘ INC => ‘-I.‘, # e.g., ‘-I. -I/usr/include/other‘ # Un-comment this if you add C files to link with later: # OBJECT => ‘$(O_FILES)‘, # link all the C files too MYEXTLIB => ‘mylib/libchen.a‘ );
MYEXTLIB => ‘mylib/libchen.a‘ 是新增的命令，作用是在生成perl 扩展包时包含libchen.a的库
修改two_test.xs 文件
#include "EXTERN.h" #include "perl.h" #include "XSUB.h" #include "ppport.h" #include "mylib/chen.h" MODULE = two_test PACKAGE = two_test void chen(name) char * name
红色部分为增加代码
编译并安装,安装需要root 权限
perl Makefile.PL make make install
编写一个测试程序two_test.pl, 测试扩展
#!/usr/bin/perl use two_test; $one = "sfjak"; &two_test::chen($one);
执行程序
perl two_test.pl
输出:
input string is : sfjak
成功调用扩展
