想用C语言写个采集程序，涉及到http相关的东西，找了找，有现成的libghttp库。
libghttp库的官方网址google一下第一条结果一般就是的：http://lfs.linuxsir.org/htdocs/blfscvs/gnome/libghttp.html

将源码包下载下来，进入例行安装流程：
1、解压

tar -xzvf libghttp-1.0.9. tar .gz
cd libghttp-1.0.9

2、安装

. /configure
make
make install

安装过种中小插曲：
在执行./configure命令的时候报错：

checking host system type ... Invalid configuration `x86_64-unknown-linux-gnu ': machine `x86_64-unknown' not recognized


checking build system type ... Invalid configuration `x86_64-unknown-linux-gnu ': machine `x86_64-unknown' not recognized


checking for ranlib... ranlib
checking for ld used by GCC... /usr/bin/ld
checking if the linker ( /usr/bin/ld ) is GNU ld... yes
checking for BSD-compatible nm... /usr/bin/nm -B
checking whether ln -s works... yes
updating cache . /config .cache
ltconfig: you must specify a host type if you use `--no-verify'
Try `ltconfig --help' for more information.
configure: error: libtool configure failed

听说在32位操作系统上一般不会有这样的错误，在64位系统上比较常见，原因是软件自身的config.guess和config.sub文件有问题，从系统中复制这两个文件到软件目录覆盖一下重新./configure就可以了(如果不知道这两个文件在哪里，用find查找一下就OK了)：

# 首先查找一下config.guess和config.sub文件的目录
find / -name config.guess
find / -name config.sub


# 将查找出来的文件随便选择一个覆盖到软件目录
cp /usr/share/automake-1 .11 /config .guess .
cp /usr/share/automake-1 .11 /config .sub .

下面是用libghttp搞了一个测试代码，成功编译和运行，证明libhttp安装成功啦：

#include
#include


main()
{
        // This is the http request object
        ghttp_request *request = NULL;
        // Allocate a new empty request object
        request = ghttp_request_new();
        // Set the URI for the request object
        ghttp_set_uri(request, "http://www.phpjiayuan.com/" );
        // Close the connection after you are done .
        ghttp_set_header(request, http_hdr_Connection, "close" );
        // Prepare the connection
        ghttp_prepare(request);
        // Process the request
        ghttp_process(request);
        // Write out the body. Note that the body of the request may not be null terminated so we have to be careful of the length.
        fwrite(ghttp_get_body(request), ghttp_get_body_len(request), 1, stdout);
        // Destroy the request. This closes any file descriptors that may be open and will free any memory associated with the reque
st.
        ghttp_request_destroy(request);
