Using C++ std streams (fstream, ofstream and ifstream) in eCos.

[grinder213]

Hi,

I'm trying to use the file stream classes of the standard C++ library together with a mounted FAT file system on a SD card. I'm using the eCoscentric release of 2.98. on a ATMEL AT91SAM9260-EK.
The regular BSD calls to the filesystem are working just fine! I use the same device paths and filenames in the two examples.

When I try to use either the fstream, ofstream or ifstream, the code compiles with no problems, but the open calls (either directly or through the constructor) never succeeds.

Is it possible to use the file stream classes the way I want to use them?

Best Regards

C++ stdlib is not supported in the public CVS.  Check the
archives as some help may be available (Zylin has some code,
eCosCentric can provide a complete package, etc)

From my previous post..

So I guess the std lib should be fully supported in my version of the code!?!?

But where am I going wonrg with the streams then?

You need to ask eCosCentric that, not us. Maybe your eCos release is
too old? Maybe you did not licensed the C++ support?

Again, ask eCosCentric. You have a support agreement with them,
otherwise you would not have eCosPro.
