Question

我正在尝试使用tar文件whalebot配置whalebot-0.02.00.tar.gz抓取工具。我用以下方法正确提取了它：

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

之后我想用：

配置它

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 ./

我该如何处理？

Answer 1

看来CMake无法找到htmlcxx库。

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

您需要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

您可能需要将#include <cstddef>添加到html/tree.h的顶部才能成功构建。它默认会安装到usr/local/。

如果您还没有安装icu，还需要安装{{3}}：

sudo apt-get install libicu-dev

最后，您现在可以构建并安装whalebot。同样，如果您有合理的最新升级安装，则可能会失败。

在webspider/src/webspider_options.cpp的第57行，您需要将boost::filesystem::initial_path().native_directory_string()替换为boost::filesystem::initial_path().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

默认情况下，这也会安装到usr/local/。

Answer 2

检查是否在CMakeLists中编写了find_library(..)或find_path(.)，然后将其替换为find_package(..)。

它解决了我的情况下的错误。

CMake错误：此项目中使用以下变量，但它们设置为NOTFOUND
