Question

我正在尝试使用qmake && make以旧学校的方式编译我的QT5项目。但是，我遇到了意想不到的错误。有~20，但这里是一个抽样（它们都很相似）：

In file included from include/Ctx.h:7:

      [-ferror-limit=]

make: *** [tmp/main.o] Error 1

下面是SrcFile.h

#ifndef SRCFILE_H
#define SRCFILE_H

#include <string>
#include <fstream>
#include "SrcObj.h"


namespace oonalysis {

class SrcFile : public SrcObj
{
public:
    SrcFile(const std::string& filename);
    std::string get_text() const;
    std::string present_name() const;
private:
    std::filebuf* get_file();
    std::string filename;
}; // class SrcFile

} // namespace oonalysis

#endif // SRCFILE_H

以下是生成的Makefile的可能部分

        $(CXX) -c $(CXXFLAGS) $(INCPATH) -o tmp/srcfile.o src/srcfile.cc

我错误配置了什么吗？有什么方法可以让两个stl版本浮动？

Answer 1

问题不直观。在一个不相关的标头gui.h中，我没有用结束括号关闭我的命名空间gui。我通过评论#include <fstream>和编译来解决这个问题。现在它工作正常。

使用qmake / make在fstream.h中的STL命名空间错误
