binary open mode

[frm]

i'm using djgpp with gcc 3.3.2 on windows 98.
i usually open a file in this way:
fstream f("file.txt", ios_base::binary);
but when i compile the code, gpp prints:
ios_base undeclared
i tried also with ios::binary, or declaring f as ifstream, but the
result is the same.
please help me!

Did you include all the necessary headers? Post the minimal complete
code that exhibits the error, and not just one line like you did.

ios and ios_base are in the std namespace, you probably need to prefix
with std::
