如何自动查找未使用的#include指令?

你可以用 PC-Lint/FlexeLint

不同寻常的是,该工具没有免费的操作系统版本。

您可以通过引用而不是通过值和前向声明来删除#includes。这是因为编译器不需要在编译时知道对象的大小。然而,这将需要代表您进行大量的手动工作。好的方面是它将减少编译时间。

您只需编写一个“暴力”命令行工具,逐条注释#includes并测试编译是否仍然有效。你有工作的时候告诉我;0)

有一个名为includator的Eclipse插件,可以帮助管理C/C++项目中的include依赖项

这是一个“暴力”VC6宏,它可以在单个 或 在编辑器中通过注释include by include并运行compile打开的文件:

Sub RemoveNotUsedIncludes()

'Check if already processed; Exit if so
ActiveDocument.Selection.FindText "//INCLUDE NOT USED", dsMatchFromStart
IF ActiveDocument.Selection <> "" THEN
    ActiveDocument.Selection.SetBookmark
    MsgBox "Already checked"
    ActiveDocument.Selection.ClearBookmark
    EXIT SUB
END IF

'Find first #include; Exit if not found
ActiveDocument.Selection.FindText "#include", dsMatchFromStart
IF ActiveDocument.Selection = "" THEN
    MsgBox "No #include found"
    EXIT SUB
END IF

Dim FirstIncludeLine
FirstIncludeLine = ActiveDocument.Selection.CurrentLine

FOR i=1 TO 200

    'Test build
    ActiveDocument.Selection.SetBookmark
    ActiveDocument.Selection = "//CHECKING... #include"
    Build
    ActiveDocument.Undo
    ActiveDocument.Selection.ClearBookmark

    IF Errors = 0 THEN
        'If build failed add comment
        ActiveDocument.Selection.EndOfLine
        ActiveDocument.Selection = " //INCLUDE NOT USED"
    END IF

    'Find next include
    ActiveDocument.Selection.EndOfLine
    ActiveDocument.Selection.FindText "#include"

    'If all includes tested exit
    IF ActiveDocument.Selection.CurrentLine = FirstIncludeLine THEN EXIT FOR

NEXT
