导读：我正在尝试使用tar文件whalebot-0.02.00.tar.gz配置whalebot爬虫.我已正确提取它： root@Admin1:~/dls# tar xvzf whalebot-0.02.00.tar.gz 之后我想配置它： root@Admin1:~/dls/whalebot# ./configure 它给了我错误： bash: ./configure: No such file or di

我正在尝试使用tar文件whalebot-0.02.00.tar.gz配置whalebot爬虫.我已正确提取它：

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

之后我想配置它：

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

它给了我错误：

bash: ./configure: No such file or directory

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 ./

CMake Error: The following variables are used in this project,but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

我该怎么办？

解决方法

看来CMake无法找到htmlcxx库.

在whalebot documentation中,htmlcxx被列为依赖项.

你需要download htmlcxx,解压缩,然后安装它：

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html / tree.h的顶部,让它成功构建.它将默认安装到usr / local /.

如果您还没有安装icu,还需要安装icu：

sudo apt-get install libicu-dev

最后,您现在可以构建和安装whalebot.同样,如果您有合理的最新boost安装,则可能会失败.

在webspider / src / webspider_options.cpp的第57行中,您需要使用boost :: filesystem :: initial_path().string()替换boost :: filesystem :: initial_path().native_directory_string().然后你应该很好地构建和安装：

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

这也将默认安装到usr / local /.
