编译See5 / C50 GPL版

Question

See5 / C5.0是从规则任务获得的数据挖掘工具

我希望为Linux编译C50，最好是为CentOS 6.x编译，但我无法编译。我也尝试过Ubuntu，但在那里也没有成功。

运行时提取后，我从C5.0版本2.07 GPL版下载了C50.tgz。/Makefile在Ubuntu18上给出了下面的错误

./Makefile: line 9: CC: command not found

如果我运行make命令，它会给出以下错误。

make c5.0 
make: /bin/csh: Command not found Makefile:60: recipe for
target 'all' failed make: *** [all] Error 127

gcc版本是：

gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0

提取C50.tgz文件后，将执行权限授予Makefile。

chmod +x Makefile

然后安装csh

sudo apt install csh

运行下面的命令以检查csh是否已安装，并检查csh版本(如果已安装)

dpkg -l csh

它应该像下面这样显示输出。

现在按照命令运行。

./Makefile

它应该给出如下的输出。(忽略警告消息)。

您将看到一个新的文件c5.0*检查命令行选项和下面的命令。

./c5.0 -h

它应该显示在输出下面。

C5.0 [Release 2.07 GPL Edition]         Fri Mar 15 17:43:39 2019
-------------------------------

    Options:
        -f <filestem>   application filestem
        -r              use rule-based classifiers
        -u <bands>      order rules by utility in bands
        -w              invoke attribute winnowing
        -b              invoke boosting
        -t <trials>     number of boosting trials
        -p              use soft thresholds
        -e              focus on errors (ignore costs file)
        -s              find subset tests for discrete atts
        -g              do not use global tree pruning
        -m <cases>      restrict allowable splits
        -c <percent>    confidence level (CF) for pruning
        -S <percent>    training sample percentage
        -X <folds>      cross-validate
        -I <integer>    random seed for sampling and cross-validation
        -h              print this message

现在，C50已经准备好使用了。下面是一个示例命令(假设sampledata.data和sampledata.names文件存在于同一个文件夹中)。

./c5.0 -r -f sampledata

成功执行命令后，将在同一个文件夹中生成sampledata.rules。
