Hello. I have been following puddinpop's topic "RPC Miners (CPU/4way/CUDA/OpenCL)" <https://bitcointalk.org/index.php?topic=2444.0>, because I have been trying to compile rpcminer-cuda. I have read every post related to that in the 15 pages.
I am not an expert (I have no idea on C++, NVCC or anything), but I do know some commands in bash. I am building a script that helps other users of Ubuntu 10.04 (may work for other versions of linux) to do the compilation automatically (I attach it if you want to read it). It is just following the steps as far as I got in the compilation, thanks to the posts of others.
As you can see, I'm trying to get some help to help myself and others. Thanks.

# 3C. Modified bitcoinminercuda.cu to "#define _BITCOIN_MINER_CUDA_"
# right above the #ifdef that checks for it.
# 3C-a. For every file named "bitcoinminercuda.cu", check if it does
# not have "#define _BITCOIN_MINER_CUDA_". If that is the case, find
# the line with "#ifdef _BITCOIN_MINER_CUDA_", and put
# "#define# _BITCOIN_MINER_CUDA_" before it
