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

# Directory of expanded packages.
#$QtSrcDir = "$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

...以下略...
}

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。

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。
