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

?

1 2	tar -xzvf libghttp-1.0.9. tar .gz cd libghttp-1.0.9

2、安装

?

1 2 3

. /configure make make install

安装过种中小插曲：
在执行./configure命令的时候报错：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

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)：

?

1 2 3 4 5 6 7 8

# 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：
