Kernel FP的MakeFile可以指定輸出文件、報告文件以及代碼文件，并且可以繼承其他的MakeFile。首先我們來看一下MakeFile的例子：
這是一個叫Project.txt的MakeFile，繼承自Default.txt和Default2.txt
1 <kfpProject>
2 <inherit path="Default.txt"/>
3 <inherit path="Default2.txt"/>
4 <code>
5 <base path="CodeBase\"/>
6 <include path="CodeA.txt"/>
7 <include path="CodeB.txt"/>
8 </code>
9 <code>
10 <include path="CodeC.txt"/>
11 <include path="CodeD.txt"/>
12 </code>
13 <output path="Output.txt"/>
14 <report path="Report.txt"/>
15 </kfpProject>
如果一部分代碼放在一個文件夾下面的話，可以使用code/base來節(jié)省書寫MakeFile的時間。讓我們看一下剩下的三個MakeFile，最后一個MakeFile被Default.txt和Default2.txt共同繼承：
Default.txt
1 <kfpProject>
2 <inherit path="Library\Library.txt"/>
3 <code>
4 <base path="DefBase\"/>
5 <include path="DefA.txt"/>
6 <include path="DefB.txt"/>
7 </code>
8 <code>
9 <include path="DefC.txt"/>
10 <include path="DefD.txt"/>
11 </code>
12 <output path="Output.txt"/>
13 <report path="Report.txt"/>
14 </kfpProject>
Default2.txt
1 <kfpProject>
2 <inherit path="Library\Library.txt"/>
3 <code>
4 <base path="Def2Base\"/>
5 <include path="Def2A.txt"/>
6 <include path="Def2B.txt"/>
7 </code>
8 <code>
9 <include path="Def2C.txt"/>
10 <include path="Def2D.txt"/>
11 </code>
12 <output path="Output.txt"/>
13 <report path="Report.txt"/>
14 </kfpProject>
他們共同繼承的Library\Library.txt
1 <kfpProject>
2 <code>
3 <base path="LibBase\"/>
4 <include path="LibA.txt"/>
5 <include path="LibB.txt"/>
6 </code>
7 <code>
8 <include path="LibC.txt"/>
9 <include path="LibD.txt"/>
10 </code>
11 <output path="LibOutput.txt"/>
12 <report path="LibReport.txt"/>
13 </kfpProject>
MakeFile分析器的第一個作用是解析MakeFile，第二個作用是生成合并的MakeFile，也就是說，要將繼承下來的所有東西進行合并，并且為所有路徑制定直接路徑而不是相對路徑。讓我們看看Project.txt合并后的結果：
1 <?xml version="1.0" encoding="gb2312" standalone="no" ?>
2 <kfpProject>
3 <output path="E:\Coding\VL++\Tools\KfpCompiler\TestData\Output.txt" />
4 <report path="E:\Coding\VL++\Tools\KfpCompiler\TestData\Report.txt" />
5 <code>
6 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\Library\LibBase\LibA.txt" />
7 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\Library\LibBase\LibB.txt" />
8 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\Library\LibC.txt" />
9 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\Library\LibD.txt" />
10 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\Def2Base\Def2A.txt" />
11 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\Def2Base\Def2B.txt" />
12 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\Def2C.txt" />
13 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\Def2D.txt" />
14 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\DefBase\DefA.txt" />
15 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\DefBase\DefB.txt" />
16 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\DefC.txt" />
17 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\DefD.txt" />
18 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\CodeBase\CodeA.txt" />
19 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\CodeBase\CodeB.txt" />
20 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\CodeC.txt" />
21 <include path="E:\Coding\VL++\Tools\KfpCompiler\TestData\CodeD.txt" />
