yaml编译与测试

yaml下载官网

下载网址

http://pyyaml.org/download/libyaml

在我写这篇文章的时候这个网站已经无法访问了，不清楚是什么原因，我最后得到的版本是yaml-0.1.7.tar.gz

编译源码

1、解压源码包

rt@ubuntu:~/yaml/yaml-0.1.7$ tar xvf yaml-0.1.7.tar.gz 

rt@ubuntu:~/yaml/yaml-0.1.7$ cd yaml-0.1.7/
2、生成makefile文件

rt@ubuntu:~/yaml/yaml-0.1.7$ ./configure --prefix=/home/rt/opt/yaml

其中--prefix=为安装路径，如果需要安装到自己系统中就不要添加后面的参数，直接./configure即可，后面的make install需要sudo权限。

3、编译、安装

rt@ubuntu:~/yaml/yaml-0.1.7$ make

rt@ubuntu:~/yaml/yaml-0.1.7$ make install

此时在安装路径下就有生成的文件了。

例子程序

1、获取软件版本号 test-version.c

#include 

#include 
#include 

#ifdef NDEBUG
#undef NDEBUG
#endif
#include 

int
main(void)
{
    int major = -1;
    int minor = -1;
    int patch = -1;
    char buf[64];

    yaml_get_version(&major, &minor, &patch);
    sprintf(buf, "%d.%d.%d", major, minor, patch);
    assert(strcmp(buf, yaml_get_version_string()) == 0);
	printf("version = %s\n", yaml_get_version_string());

    /* Print structure sizes. */
    printf("sizeof(token) = %d\n", sizeof(yaml_token_t));
    printf("sizeof(event) = %d\n", sizeof(yaml_event_t));
    printf("sizeof(parser) = %d\n", sizeof(yaml_parser_t));

    return 0;
}

执行gcc test-version.c -o version -lyaml -I/home/rt/opt/yaml/include -L/home/rt/opt/yaml/lib

运行结果

rt@ubuntu:~/yaml$ ./version 
version = 0.1.7
sizeof(token) = 40
sizeof(event) = 56
sizeof(parser) = 248

读取并解析yaml文件 run-scanner.c
