Compilation error in pair_scan.cu

[GoogleCodeExporter]

Please post a short code sample which reproduces the problem:
I tried to compile the pair_scan.cu file from thrust/testing dir and it give 
compilation error.

What is the expected output? What do you see instead?
I want an error free compilation as I have not added anything to the code.

What version of Thrust are you using? Which version of nvcc?  Which host
compiler?  On what operating system?
Iam using the current version of thrust on linux platform.

Please provide any additional information below.

This is not a bug.  testframework.o must be linked against.

• Changed state: Invalid

[GoogleCodeExporter]

Could you please tell me what is testframework.o and how should it be linked? I 
did not require this to compile any other files?

Ok, i linked teatframework.h in the pair_scan code and now i get the following 
error
