我的安装程序的大小可以减小吗？

目前我的 GoogleAuthAndSync 支持实用程序有此代码：

; Google Calendar Interface v3
Source: "Google.Apis.Auth.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Google.Apis.Auth.PlatformServices.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Google.Apis.Calendar.v3.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Google.Apis.Core.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Google.Apis.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Google.Apis.PlatformServices.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Google.GData.Client.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Google.GData.Contacts.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Google.GData.Extensions.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "GoogleAuthandSync.exe"; DestDir: "{app}"; Flags: ignoreversion
Source: "GoogleAuthandSync.exe.config"; DestDir: "{app}"; Flags: ignoreversion
Source: "Microsoft.Threading.Tasks.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Microsoft.Threading.Tasks.Extensions.Desktop.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Microsoft.Threading.Tasks.Extensions.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "Newtonsoft.Json.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "System.Net.Http.dll"; DestDir: "{app}"; Flags: ignoreversion
Source: "System.Net.Http.Extensions.dll"; DestDir: "{app}"; Flags: ignoreversion
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：

; 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

我刚刚更新了两个项目上的所有 Nuget 包，这是 DLL 文件的结果：

现在许多 DLL 文件的日期相同，等等。那么，有没有办法将受影响的文件只添加一次到安装程序中并部署到两个位置？

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：

[ISPP]
#define SourceDir "..\Meeting Schedule Assistant\Release"
[Setup]
SourceDir={#SourceDir}

【问题讨论】：

可以使用Excludes参数排除“语言资源dll文件”。

【解决方案1】：

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。 Inno Setup 将compile a source file only once to the installer, when used multiple times.

由于您使用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。

[Files]
#pragma parseroption -p-

#define FileEntry(Source, DestPath) \
    "Source: " + Source + "; DestDir: " + DestPath + "\n"

#define GetFileTimestamp(Path) GetFileDateTimeString(Path, 'dd/mm/yyyy hh:nn:ss', '-', ':')

#define ProcessFile(RootPath, Path, AlternativePath, DestPath, FindResult, FindHandle) \
    FindResult ? \
        Local[0] = FindGetFileName(FindHandle), \
        Local[1] = AddBackslash(Path) + Local[0], \
        Local[2] = AddBackslash(AlternativePath) + Local[0], \
        Local[3] = AddBackslash(RootPath) + Local[1], \
        Local[4] = AddBackslash(RootPath) + Local[2], \
        Local[5] = \
           FileExists(Local[4]) && \
           (GetFileTimestamp(Local[3]) == GetFileTimestamp(Local[4])), \
        FileEntry((Local[5] ? Local[2] : Local[1]), DestPath) + \
        ProcessFile(RootPath, Path, AlternativePath, DestPath, \
            FindNext(FindHandle), FindHandle) \
    : ""

#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\Release", "OutlookCalIFConsole", ".", \
    "{app}\OutlookCalIFConsole")

或者您可以使用SetupSetting 来读取SourceDir 指令：

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

如果你add SaveToFile to the end of the script:

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

...那么您应该在Preprocessed.iss 中看到类似的内容：

[Files]
Source: OutlookCalIFConsole\CommandLine.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\Microsoft.Graph.Core.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\Microsoft.Graph.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\Microsoft.Identity.Client.dll; Dest: {app}\OutlookCalIFConsole
Source: .\Newtonsoft.Json.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\System.Console.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\System.IO.dll; Dest: {app}\OutlookCalIFConsole
Source: .\System.Net.Http.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\System.Reflection.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\System.Reflection.TypeExtensions.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\System.Runtime.dll; Dest: {app}\OutlookCalIFConsole
Source: OutlookCalIFConsole\System.Runtime.Extensions.dll; Dest: {app}\OutlookCalIFConsole
Source: .\System.Security.Cryptography.Algorithms.dll; Dest: {app}\OutlookCalIFConsole
Source: .\System.Security.Cryptography.Encoding.dll; Dest: {app}\OutlookCalIFConsole
Source: .\System.Security.Cryptography.Primitives.dll; Dest: {app}\OutlookCalIFConsole
Source: .\System.Security.Cryptography.X509Certificates.dll; Dest: {app}\OutlookCalIFConsole

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

除了通过GetFileDateTimeString（间接通过GetFileDateTimeString）比较文件，您还可以使用GetFileVersion（因为文件是DLL）。

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。

【解决方案2】：

我找到了允许 InnoSetup 编译器在压缩过程中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：

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 版本为 6.0.2 (u)
