streamScatterOp

Hi,
I understand that streamScatterOp is still not fully supported, but I read on the forum people using it. I decided to give it a try under Windows XP x64, and latest SDK.

I tried to run brcc & C/C++ cl/link on the scatter_gather.br which comes under Brook+ samples with the SDK.
I always get an error complaining from undefined variable corresponding to the reduce function. For example:
....
...
reduce void sub(float a<>, reduce float b<>)
{
b = a - 1;
}
...
...
streamScatterOp(soutput1D, sindices1D, input1D, sub);
....

I always get : undefined __sub_inner_cpu from the C/C++

Thanks
Amr

The sample "scatter_gather" from Brook+ 1.01v BETA runs fine on my 4850. I have not tried this on the 2900XT yet.

I am using VS2005 on WinXP32 (can't wait for the Vista64 support!).

thanks Ryta123
I am using 3870 with XP x64. The precompiled binaries run fine, it is the compilation only that causes this error. Maybe I will tryXP 32
