c语言中嵌入perl函数

c代码interp.c

#include <EXTERN.h>
#include <perl.h>

static PerlInterpreter *my_perl;

int main(int argc, char **argv, char **env)
{
	char *args[] = { NULL };
	PERL_SYS_INIT3(&argc,&argv,&env);
	my_perl = perl_alloc();
	perl_construct(my_perl);
	perl_parse(my_perl, NULL, argc, argv, NULL);
	PL_exit_flags |= PERL_EXIT_DESTRUCT_END;

	call_argv("Hello", G_DISCARD | G_NOARGS, args);
	perl_destruct(my_perl);
	perl_free(my_perl);
	PERL_SYS_TERM();
}

编译

gcc -o interp interp.c `perl -MExtUtils::Embed -e ccopts -e ldopts`

perl代码hello.pl

#!/usr/bin/perl 
# 函数定义
sub Hello{
   print "Hello, World!\n";
}

# 函数调用
Hello();

运行

$ ./interp hello.pl 
Hello, World!
