CMake錯誤：下列變量用於此項目，但它們被設置爲NOTFOUND

Question

我試圖用tar文件whalebot-0.02.00.tar.gz配置whalebot爬網程序。

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

之後，我想與配置它：我與正確提取它

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

它給我的錯誤：

bash: ./configure: No such file or directory

也我已經運行命令：

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

它給了我以下翅膀結果：

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

我該如何繼續？

Answer 1

看來CMake無法找到htmlcxx庫。

在whalebot documentation中，htmlcxx被列爲依賴項。

您需要download htmlcxx，解壓縮，然後再進行安裝：

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頂部得到它成功打造。它將默認安裝到usr/local/。

你還需要安裝icu如果你不已經擁有了它：

sudo apt-get install libicu-dev 

最後，您現在就可以編譯和安裝whalebot。同樣，如果你有一個合理的最新升壓安裝，可能會失敗。

在webspider/src/webspider_options.cpp的第57行中，您需要將替換爲boost::filesystem::initial_path().string()。那麼你應該很好地構建和安裝：

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

默認情況下，它也會安裝到usr/local/。
