CMake错误：本项目中使用了以下变量，但它们被设置为NOTFOUND

我正在尝试配置whalebot带有 tar 文件的爬虫whalebot-0.02.00.tar.gz。我已正确提取它：

root@Admin1:~/dls# tar xvzf whalebot-0.02.00.tar.gz

之后我想对其进行配置：

root@Admin1:~/dls/whalebot# ./configure

它给了我错误：

bash: ./configure: 没有这样的文件或目录

我也运行了命令：

root@Admin1:~/dls/whalebot# cmake ./

它给了我以下结果：

root@Admin1:~/dls/whalebot# cmake ./

我该如何继续？

看来 CMake 无法找到 htmlcxx 库。

In the 鲸鱼机器人文档 http://code.google.com/p/whalebot/wiki/GettingStarted, htmlcxx 被列为依赖项。

你需要下载 htmlcxx http://sourceforge.net/projects/htmlcxx/，解压，然后安装：

cd <path to unzipped htmlcxx>
./configure --enable-static=on --enable-shared=off
make
sudo make install

您可能需要添加#include <cstddef>到顶部html/tree.h让它成功构建。它将安装到usr/local/默认情况下。

你还需要icu http://site.icu-project.org/如果您还没有安装，请安装：

sudo apt-get install libicu-dev

最后，您现在可以构建并安装 Whalebot。同样，如果您安装了相当最新的 boost，则 make 可能会失败。

在第 57 行webspider/src/webspider_options.cpp，你需要更换boost::filesystem::initial_path().native_directory_string() with boost::filesystem::initial_path().string()。然后你应该可以很好地构建和安装：

cd <path to unzipped whalebot>
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make
sudo make install

这也将安装到usr/local/默认情况下。
