QtCreator构建系统在OSX升级后损坏 [英] QtCreator build system is broken after OSX upgrade

问题描述

我最近将OSX升级为山狮，因为我无法使用Qt Creator编译我的项目。我收到一堆错误，如下所示：

I recently upgraded my OSX to mountain lion and ever since I cannot compile my project using Qt Creator anymore. I get bunch of errors like the following:

/Users/user/codes/lib/io/xdmfWriter.cpp:63：error：explicit 'std :: basic_ostream< _CharT，_Traits>& std :: operator<<<<（std :: basic_ostream< _CharT，_Traits>& const std :: basic_string< _CharT，_Traits，_Alloc>& ，_Alloc = std :: allocator< char>]'但没有可用的定义

/ Users / user / codes /lib/io/xdmfWriter.cpp:-1：在实例化'std :: basic_ostream< _CharT，_Traits>& std :: operator<<<<（std :: basic_ostream< _CharT，_Traits>& const std :: basic_string< _CharT，_Traits，_Alloc>& ，_Alloc = std :: allocator< char>]'：

/ Users / user / codes / io / xdmfWriter.cpp：63：从这里实例化

// xdmfWriter.cpp -- line 63:
gridName << xdmfName_ << "." << timeStep;

gridName 是 std :: ostringstream 对象和 xdmfName _ 是一个 std :: string 类的 xdmfWriter 类的私有成员，并在类构造函数中初始化。我之前没有这个问题...任何想法？

gridName is a std::ostringstream object and xdmfName_ is a std::string variable declared as a private member of the xdmfWriter class and initialized in the class constructor. I did not have this problem before ... Any ideas?

推荐答案

这可以通过添加 c_str（）如：

gridName << xdmfName_.c_str() << "." << timeStep;

但是，这不是永久的解决方案。

However, this is not a permanent solution.

您需要更改 $ QTDIR / mkspecs / common / g ++中的 -mmacosx-version-min = 10.5 -macx.conf 至 -mmacosx-version-min = 10.7 。
这是因为10.5或10.6的SDK不包括在Mountain Lion和XCode 4.4中。

You need to change -mmacosx-version-min=10.5 in $QTDIR/mkspecs/common/g++-macx.conf to -mmacosx-version-min=10.7. This is because SDKs for 10.5 or 10.6 are not included in Mountain Lion and XCode 4.4.
