Windows下MinGW编译静态Qt I 之实践

# 文件夹结构 #

Qt动态环境安装路径 D:\\Qt\\MinGW\\

Qt静态环境路径 D:\\Qt\\MinGW\\Static

Qt源代码目录   D:\\Qt\\MinGW\\Static\\src\\ //解压源代码到此目录下，长这个样子

# 修改脚本 #

function Main
    {
        # Check that 7zip is installed. We use it to expand the downloaded archive.
        #[void] (Get-7zip) #手动解压，跳过验证7-zip
    
        # Get Qt source file name from URL.
        $QtSrcFileName = Split-Path -Leaf $QtSrcUrl
    
        # If Qt version is not specified on the command line, try to extract the value.
        if (-not $QtVersion) {
            $QtVersion = $QtSrcFileName -replace "`.[^`.]*$",''
            $QtVersion = $QtVersion -replace 'qt-',''
            $QtVersion = $QtVersion -replace 'everywhere-',''
            $QtVersion = $QtVersion -replace 'opensource-',''
            $QtVersion = $QtVersion -replace 'src-',''
            $QtVersion = $QtVersion -replace '-src',''
        }
        Write-Output "Building static Qt version $QtVersion"
    
        # Qt installation directory.
        $QtDir = "$QtStaticDir\$QtVersion"
    
        # Get MinGW root directory, if not specified on the command line.
        if (-not $MingwDir) {
            # Search all instances of gcc.exe from C:\Qt prebuilt environment.
            $GccList = @(Get-ChildItem -Path C:\Qt\*\Tools\mingw*\bin\gcc.exe | ForEach-Object FullName | Sort-Object)
            if ($GccList.Length -eq 0) {
                Exit-Script "MinGW environment not found, no Qt prebuilt version?"
            }
            $MingwDir = (Split-Path -Parent (Split-Path -Parent $GccList[$GccList.Length - 1]))
        }
        Write-Output "Using MinGW from $MingwDir"
    
        # Build the directory tree where the static version of Qt will be installed.
        #Create-Directory $QtStaticDir\src    #已手动创建，且源代码已解压到此路径下
        Create-Directory $QtDir
    
        # Download the Qt source package if not yet done.
        #Download-File $QtSrcUrl $QtStaticDir\src\$QtSrcFileName #跳过下载代码包

        #$QtSrcDir = "$QtStaticDir\src\$((Get-Item $QtStaticDir\src\$QtSrcFileName).BaseName)"
        $QtSrcDir = "$QtStaticDir\src\qt-everywhere-opensource-src-5.5.0" #手动指定源代码目录
    
        # Expand archives if not yet done
        #Expand-Archive $QtStaticDir\src\$QtSrcFileName $QtStaticDir\src $QtSrcDir #跳过解压源代码包

    }

# 执行脚本 #

在PowerShell中执行脚本，

PS D:\Qt> .\windows-build-qt-static.ps1 -QtStaticDir 'D:\Qt\MinGW\Static' -QtVersion 'Qt5.5.0' -MingwDir 'D:\Qt\MinGW\Qt5.5.0\Tools\mingw492_32\'
    
    -QtStaticDir 'D:\Qt\MinGW\Static'    #默认为c:\Qt\Static
    -QtVersion 'Qt5.5.0'                 #脚本解析为5.5.0，运行过程出现报错。手动指定版本号解决了。
    -MingwDir 'D:\Qt\MinGW\Qt5.5.0\Tools\mingw492_32\' #若不指定，脚本会从默认安装路径找C:\Qt\*\Tools\mingw*\bin\gcc.exe

# 遇到的问题 #

PowerShell执行脚本提示“无法加载文件”

Set-ExecutionPolicy RemoteSigned

参考[powershell-无法加载文件,因为在此系统中禁止执行脚本][powershell-]。

附注

自行下载源代码并解压，修改后的脚本在我的机器上运行花了1小时45分。
