/usr/bin/ld: cannot find -lcutil_x86_64 (ubuntu 10.04 CUDA 3.0)

My platform:

GPU: GeForce 8800GT

OS: Ubuntu 10.04 x64

CUDA Driver: 195.36.15

CUDA Toolkit: 3.0

CUDA SDK: 3.0

I had installed the CUDA SDK/Toolkit 3.0 and had try to build the samples from SDK, all done right, I can run all the samples now.

and then, I download a CUDA benchmark source code and try to build it ( of course, this benchmark is not worten by me, I am just interesting) :

http://www.eecg.toronto.edu/~moshovos/CUDA…robenchmark.zip

this zip file was extract to “/home/edison/NVIDIA_GPU_Computing_SDK/projects/microbenchmark”

I had modify the “ROOTDIR=” of the “Makefile” to “/home/edison/NVIDIA_GPU_Computing_SDK/projects” ;

and replace the “common.mk” with the one that I success build for SDK samples ;

and copy the cutil.h to “/home/edison/NVIDIA_GPU_Computing_SDK/projects/microbenchmark” ;

and copy the folders: “common”, “lib” to “/home/edison/NVIDIA_GPU_Computing_SDK/projects/microbenchmark”

and type “make”, the building is running but after a few minutes, i get such error info:

edison@edison-desktop://home/edison/NVIDIA_GPU_Computing_SDK/projects/microbenchmark$ make

chmod a+x build_cubin

/usr/bin/ld: cannot find -lcutil_x86_64

collect2: ld returned 1 exit status

make: *** [bin/linux/release/main] Error 1

so, how can I fix this “/usr/bin/ld: cannot find -lcutil_x86_64” problem ?

thanks !

Try searching the forums next time…

N.

Thanks.

Try adding -L/path_to_sdk/NVIDIA_GPU_Computing_SDK/C/lib to the link command, where 'path_to_sdk' depends on where you installed the sdk.

but sorry, how can I do this :) … I am just new on this.
