不要在 Inno Setup 安装程序中多次包含重复文件


Do not include duplicate files multiple times in the Inno Setup installer

可以减小我的安装程序的大小吗？

目前我的 GoogleAuthAndSync 支持实用程序有以下代码：

Source:"System.Net.Http.Primitives.dll"; DestDir:"{app}"; Flags: ignoreversion
Source:"Zlib.Portable.dll"; DestDir:"{app}"; Flags: ignoreversion

如您所见，这些文件被安装到 {app} 文件夹中。我没有使用通配符的原因是因为我也有语言资源 dll 文件并且不想包含它们。

然后，我将 OutlookCalIFConsole 实用程序安装到子文件夹中：

1
2

; Outlook Calendar Interface
Source:"OutlookCalIFConsole\\*.dll"; DestDir:"{app}\\OutlookCalIFConsole"; Flags: ignoreversion
Source:"OutlookCalIFConsole\\OutlookCalIFConsole.exe"; DestDir:"{app}\\OutlookCalIFConsole"; Flags: ignoreversion sign
Source:"OutlookCalIFConsole\\OutlookCalIFConsole.exe.config"; DestDir:"{app}\\OutlookCalIFConsole"; Flags: ignoreversion

现在许多 DLL 文件的日期相同，等等。那么，有没有办法只将受影响的文件添加到安装程序中一次并部署到两个位置？

我不想让事情过于复杂或给自己造成维护问题。

请注意，我还设置了 SourceDir 指令：

1
2
3
4
5
[ISPP]
#define SourceDir"..\\Meeting Schedule Assistant\
elease"
[Setup]
SourceDir={#SourceDir}
相关讨论

我找到了允许 InnoSetup 编译器在压缩期间成功删除重复文件的解决方案，我的配置中感兴趣的部分是：

1
2
3
4
5
6
Compression=lzma2/ultra64
LZMANumBlockThreads=4
CompressionThreads=4
LZMADictionarySize=262144 ; this allows to find duplicated files and succesfully deduplicate them (but compressor consumes up to 2.5GB / ram during compilation)
LZMAUseSeparateProcess=yes
SolidCompression=yes

InnoSetup 版本是 6.0.2 (u)

您可以使用预处理器来迭代子文件夹中的 DLL 文件，并将它们与基础文件夹中的文件进行比较。如果它们匹配，则使用基本文件夹中的文件作为源。多次使用时，Inno Setup 只会将源文件编译一次给安装程序。

由于使用了 SourceDir 指令(预处理器显然不知道)，代码有些复杂。如果没有指令，代码会更简单。

#define ProcessFolderWithAlternativeSource(RootPath, Path, AlternativePath, DestPath) \\
    Local[0] = FindFirst(AddBackslash(AddBackslash(RootPath) + Path) +"*.dll", 0), \\
    ProcessFile(RootPath, Path, AlternativePath, DestPath, Local[0], Local[0])

#pragma parseroption -p+

#emit ProcessFolderWithAlternativeSource( \\
   "..\\Meeting Schedule Assistant\
elease","OutlookCalIFConsole",".", \\
   "{app}\\OutlookCalIFConsole")

或者你可以使用 SetupSetting 来读取 SourceDir 指令：

1
2
#emit ProcessFolderWithAlternativeSource( \\
    SetupSetting("SourceDir"),"OutlookCalIFConsole",".","{app}\\OutlookCalIFConsole")

如果将 SaveToFile 添加到脚本的末尾：

1
#expr SaveToFile(AddBackslash(SourcePath) +"Preprocessed.iss")

... 那么您应该在 Preprocessed.iss:

中看到类似的内容

注意 Newtonsoft.Json.dll、System.Net.Http.dll 和 System.Security.Cryptography.* 的条目。

您也可以使用 GetFileVersion(因为文件是 DLL)，而不是通过 GetFileDateTimeString(间接通过 GetFileDateTimeString)比较文件。

如果您需要在 [Files] 部分条目中添加其他参数，请相应地修改 FileEntry 宏。
