Hi...

I have compiled a program on an earlier version of Mandrake.. and it all works fine.

However, when I port the program to Mandrake 9.1, the compiler cannot compile the code that uses the fstream class. I.e. it cannot find the include files for it.

On the previous version of Mandrake there was a Gcc++ (i think) directory that held the fstream include, which does not seem to be present under Mandrake 9.1.

Does anyone have any idea how I can get this code to compile?

Or is there another class I can use instead of fstream, to get output to a file?

Thanks in advance!

Could you post the error messages that the compiler gives you?

Sorry the comp I was using was at work...

From what I recall, I was using a ofstream to define a file to write to.. and the error message was something like.... "ofstream used as a type, but not defined as a type".... hence I assumed that it could not find the relevant include file.

The I searched /usr/include for fstream include file.. but on Mandrake 9.1 it was not present, where as on the previous version of Linux it was in a gcc+ directory.

Posting a bit of code would help too. Were you using <fstream> or <fstream.h>? You should be using <fstream> as <fstream.h> is deprecated. You also need to be aware that <fstream> puts everything into the std namespace, so you should use something like a "using namespace std;" line, or reference ofstream as std::ofstream.

Other possibilities are that you are using gcc to compile instead of g++. g++ is the GNU C++ compiler, gcc is the GNU C compiler.

Also, make sure you have all the necessary gcc/g++ packages installed.
