我对这个编译器错误感到困惑,我无法弄清楚我的生活是怎么回事。整个错误对我来说并没有多大意义,而且大多数代码都是从以前工作正常的项目中复制的,这使得它更加奇怪。
错误和代码如下:
1>ClCompile:
1> main.cpp
1>c:\program files (x86)\microsoft visual studio 10.0\vc\include\fstream(1347): error C2248: 'std::basic_ios<_Elem,_Traits>::basic_ios' : cannot access private member declared in class 'std::basic_ios<_Elem,_Traits>'
1> with

1> _Traits=std::char_traits<char>
1> ]
1> c:\program files (x86)\microsoft visual studio 10.0\vc\include\ios(176) : see declaration of 'std::basic_ios<_Elem,_Traits>::basic_ios'

1> ]

这是 main.cpp *的非常小的代码:
#include <Mage/File/PlainText.h>
#include <cstdio>
int main(int argc, char** argv) {
Mage::FilePlainText file = Mage::FilePlainText("shadow_pcf_gaussian_fragment.glsl");
printf("%s\n", file.content().c_str());
while (true) { }
return 0;
}
代码 file.content():
Mage::String FilePlainText::content() {
Mage::String src;
try {
open();
// We allocate enough memory to copy the entire content to memory.
mHandle.seekg(0, std::ios::end);
src.reserve(mHandle.tellg());
// Set pointer to 0 and copy to memory.
mHandle.seekg(0, std::ios::beg);
src.assign((std::istreambuf_iterator<char>(mHandle)),
std::istreambuf_iterator<char>());
close();
} catch (Mage::Exception& e) {
throw e;
}
return src;
}
我的猜测是它与此有关。
答案 0 :(得分:3)
我猜FilePlainText
是(直接或间接)从fstream
派生的,或者是fstream
类型的成员(在这种情况下,复制构造函数会尝试复制)是不可复制的,所以
Mage::FilePlainText file = Mage::FilePlainText("shadow_pcf_gaussian_fragment.glsl");
是非法的。为什么不简单:
Mage::FilePlainText file("shadow_pcf_gaussian_fragment.glsl");
我怀疑你真的想要复制初始化。
编辑 - 您应该制作FilePlainText
private
的复制构造函数,以防止尝试复制它。
