# Script to modify the source to build rpcminer with CUDA support

echo "Make sure to have installed the CUDA drivers and toolkit";
echo "You can go to https://developer.nvidia.com/cuda-downloads";

# 0.  Prepare the environment
Unpack the zip file with the source and go into the folder
unzip -q -d rpcminer `ls bitcoin-remote-rpc-*-src.zip` && cd rpcminer

# 1.  Open up the CMakeLists.txt.  There's a group of seven options
# (lines 5-11 in my version of the file for me).  I set "Enable CUDA
# miner" and "Build RPC miner" to ON and everythign else to OFF.
sed -i 's-\(OPTION(BITCOIN_\(ENABLE\|BUILD\)_\(OPENCL\|REMOTE\|GUI\|DAEMON\).*\)ON)-\1OFF)-g;' CMakeLists.txt;

# 2. Ran cmake → go to step 4

# 3.  Cleaned up some compile errors:
# 3A.  Added "#include "
# and "using namespace boost;" to serialize.h after the rest of the
# #includes
# 3A-a. Find last line with #include (after the boost library;
# there is another include near line 1112)
last_line_include_boost=`sed -n '/\#include.*boost/=' ./src/serialize.h | tail -n 1`;
# 3A-b. Add both "#include " and "using namespace boost;"
sed -i $last_line_include_boost's-^\(.*\)$-\1\n\#include \nusing namespace boost\;-g' ./src/serialize.h;
# 3C.  Modified bitcoinminercuda.cu to "#define _BITCOIN_MINER_CUDA_"
# right above the #ifdef that checks for it.
# 3C-a. For every file named "bitcoinminercuda.cu", check if it does
# not have "#define _BITCOIN_MINER_CUDA_". If that is the case, find
# the line with "#ifdef _BITCOIN_MINER_CUDA_", and put
# "#define# _BITCOIN_MINER_CUDA_" before it
for i in `find ./ -iname 'bitcoinminercuda.cu'`; do
   if [[ -z `grep '#define _BITCOIN_MINER_CUDA_' "$i"` ]]; then
      sed -i '/\#ifdef _BITCOIN_MINER_CUDA_/{x;s-.*-\#define _BITCOIN_MINER_CUDA_-;p;x}' "$i";
   fi;
done;

#4.  Ran make → Ran cmake and make
cmake ./ && make

#5.  Build the appropriate ".cubin" file
fad
#5A. Ask the user to input the correct version of the compute
#capabilities for their GPU
# http://wiki.blender.org/index.php/Dev:2.6/Source/Render/Cycles/Building
# http://ondoc.logand.com/d/365/html
# https://en.wikipedia.org/wiki/CUDA
# http://docs.nvidia.com/cuda/cuda-c-programming-guide/
#5A-a. Print message with the link to find the right information
echo "Visit the website https://developer.nvidia.com/cuda-gpus";
echo "and look for the Compute Capability corresponding to the model";
echo "of your GPU. Then input the number and press enter";
#5A-b. Read value from standard input
read GPU_CompCap;
#5A-c. Delete the period in the version
GPU_CompCap=`echo "$GPU_CompCap" | tr -d '.'`;
#5A-d. Run nvcc to compile the cubin file
nvcc ./src/cuda/bitcoinminercuda.cu -gencode arch=compute_"$GPU_CompCap",\"code=sm_$GPU_CompCap,compute_$GPU_CompCap\" --keep
