I recently updated one of my machines to -current to adapt some code to
build under the new version of gcc (3.2.2). However, file IO using <fstream>
gives error messages about implicit typenames being deprecated, and I can't
for the life of me figure out what to do my code to make the compiler happy.
Has anyone encountered this?
Below is a small example illustrating the problem. The source below should
compile fine on a previous version of g++, as in -stable. However, it will
not compile on -current using g++ 3.3.2. Does anyone know what to do to the
simple source below to get it to compile happily under -current?
(yes, I have checked gnu gcc's mailing list and FAQ/docs. I can't find an
adequate explanation for it. I suspect it has something to do with stricter
conformance to the finalized C++ standard, but since I am still a novice any
explanation by gcc developers would probably have slipped by me)
---------
#include <fstream>
int main()
{
std::ofstream afile("test.txt");
afile << "some data";
}
