c++ - 体系结构 x86_64 : "_CFBundleCopyResourceURL", 的 undefined symbol

Question

尝试使用 Qt 访问 Mac .app 包中资源文件夹的文件路径。这是我的代码:

CFURLRef appUrlRef;


appUrlRef = CFBundleCopyResourceURL(CFBundleGetMainBundle(), CFSTR("AFE-MP-512"),NULL,NULL);
CFStringRef filePathRef = CFURLCopyPath(appUrlRef);



qDebug() << filePathRef;

// Release references
CFRelease(filePathRef);
CFRelease(appUrlRef);

我唯一拥有的是表单上用于运行代码的按钮。尝试编译时出现以下错误:

Undefined symbols for architecture x86_64:
  "_CFBundleCopyResourceURL", referenced from:
      MainWindow::on_pushButton_clicked() in mainwindow.o
  "_CFBundleGetMainBundle", referenced from:

  "_CFRelease", referenced from:

  "___CFConstantStringClassReference", referenced from:
      CFString in mainwindow.o

Error while building/deploying project ProgramLaunch (kit: Desktop Qt 5.3 clang 64bit)

我在 mainwaindow.h 中包含以下内容

#include <QtCore>
#include <CoreFoundation/CFURL.h>
#include <CoreFoundation/CFBundle.h>

有什么可能出错的想法吗？谢谢

您需要链接到 CoreFoundation 框架。您可以将以下内容添加到您的 qmake 项目中:

LIBS += "-framework CoreFoundation"
