C++ compilation error

Question

C++ / C#

When writing
#include and trying to compile, the following message appears:

/usr/include/c++/4.5/bits/ios_base.h: In copy constructor 'std::basic_ios::basic_ios(const std::basic_ios&)':
/usr/include /c++/4.5/bits/ios_base.h:785:5: error: 'std::ios_base::ios_base(const std::ios_base&)' is private
/usr/include/c++/4.5/iosfwd:77:11: error: within this context

main.cpp:27:54: error: initializing argument 1 of 'void Replace::replace_strings(std::ifstream, std::ofstream, std::string, std::string)'
make: *** [main.o] Error 1

if I remove this Include, messages like error are displayed : variable 'std::ifstream fin' has initializer but incomplete type, which is obvious

$g++ --version
g++ (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2

How do I get rid of this error?

Answer 1

[telepath mode on]
Header file, probably fstream. The problem is most likely that you are passing std::ifstream to the function by value, not by reference.

Answer 2

What do you think yourself, according to the data you provided and without a crystal ball, you can determine the error?
What is "this inclusion". Can't you call it? (Or habroparser ate :)?)
Where is the code that you have in main?

Answer 3

I don’t rummage in C++, but phrases like “error: blah blah is private” suggest that you are trying to access private methods =)
