multiple definition of `_impure_ptr'

[samf48]

Hello all, I am trying to build an application that I had previously built for a regular x86 PC platform using an Atmel At91sam7s-ek development board.  My issue is that it keeps coming up with a “multiple definition of ‘_impure_ptr'” error in the output.  I know I’ve set everything up right because I was able to build and deploy the blinking LED just fine.  That is what I am using as the basis for this project.  I am adding my source files and .h files one by one until I have a fully running application on the board.  Can anyone point me in the right direction for what I can do to understand this error? My output log is posted below.

Thank you!

Just in case anyone is curious, what I did to fix this was comment out these two lines in stdio.c:

// Required for proper compilation.
struct _reent r = {0, (FILE *) 0, (FILE *) 1, (FILE *) 0};
struct _reent *_impure_ptr = &r;

Hi,

Thanks for sharing this. Looks like the Atmel libraries were designed for an older version of the toolchain that did not define _impure_ptr properly. Commenting it out should indeed resolve the problem.
