So, I finally found how to see the invoked command!

Here is the full output with the command. The libraries do exist, so why on earth it can not link :(

mahmood@vb:AES$ g++ -fPIC -L/home/mahmood/boost_1_54_0/stage/lib -lboost_filesystem -lboost_system  -m64 -o /home/mahmood/gpgpu-sim_distribution/ispass2009-benchmarks/bin/release/AES   obj/x86_64/release/aescuda.cpp.o obj/x86_64/release/aesCudaUtils.cpp.o  obj/x86_64/release/aesHost.cu.o        -L/usr/local/cuda/lib64 -L/home/mahmood/NVIDIA_GPU_Computing_SDK/C/src//../lib -L/home/mahmood/NVIDIA_GPU_Computing_SDK/C/src//../common/lib/linux -L/home/mahmood/NVIDIA_GPU_Computing_SDK/C/src//../../shared//lib -lcudart    -L/usr/local/cuda/lib64 -L/home/mahmood/NVIDIA_GPU_Computing_SDK/C/src//../lib -L/home/mahmood/NVIDIA_GPU_Computing_SDK/C/src//../common/lib/linux -L/home/mahmood/NVIDIA_GPU_Computing_SDK/C/src//../../shared//lib -lcudart -lcutil_x86_64  -lshrutil_x86_64

Does adding –v option (verbose) to this line tell you anything helpful?

(like the directories it is searching?  - or, more likely, not searching ;-)  )
