macOS 下编译 qt 静态版

前提

• 安装 xcode
• 安装 xcode command line tools

下载 qt-everywhere-opensource-src-5.7.1.tar.gz

tar -xzvf qt-everywhere-opensource-src-5.7.1.tar.gz
cd qt-everywhere-opensource-src-5.7.1
vi build.sh

build.sh

#!/bin/sh

./configure -static -debug-and-release -nomake examples -nomake tests -prefix ~/Qt/5.7.1_static_osx -qt-sql-sqlite -plugin-sql-sqlite -qt-libpng -qt-libjpeg -qt-zlib -qt-pcre -opensource -confirm-license -opengl -qt-freetype

chmod +x ./build.sh
./build.sh

make
make install

或者多核处理器

make -j8
make -j8 install

错误信息

编译 qt 5.7.1 下出现错误

fontdatabases/mac/qfontengine_coretext.mm:775:20: error: qualified reference to
      'QFixed' is a constructor name rather than a type in this context
    return QFixed::QFixed(int(CTFontGetUnitsPerEm(ctfont)));

qtbase/src/platformsupport/fontdatabases/mac/qfontengine_coretext.mm
修改为

return QFixed(int(CTFontGetUnitsPerEm(ctfont)));

qt/qtbase/src/plugins/platforms/cocoa/qcocoahelpers.h

OSStatus qt_mac_drawCGImage(CGContextRef inContext, const CGRect *inBounds, CGImageRef inImage);

改为

void qt_mac_drawCGImage(CGContextRef inContext, const CGRect *inBounds, CGImageRef inImage);

qt/qtbase/src/plugins/platforms/cocoa/qcocoahelpers.mm 改为

void qt_mac_drawCGImage(CGContextRef inContext, const CGRect *inBounds, CGImageRef inImage)
{
    // Verbatim copy if HIViewDrawCGImage (as shown on Carbon-Dev)
    OSStatus err = noErr;

//    require_action(inContext != NULL, InvalidContext, err = paramErr);
//    require_action(inBounds != NULL, InvalidBounds, err = paramErr);
//    require_action(inImage != NULL, InvalidImage, err = paramErr);

    CGContextSaveGState( inContext );
    CGContextTranslateCTM (inContext, 0, inBounds->origin.y + CGRectGetMaxY(*inBounds));
    CGContextScaleCTM(inContext, 1, -1);

    CGContextDrawImage(inContext, *inBounds, inImage);

    CGContextRestoreGState(inContext);
//InvalidImage:
//InvalidBounds:
//InvalidContext:
//        return err;
