this is what my configure code looks like to get it to compile with a fresh git clone not the linux branch
I am compiling on ubuntu 14.04

NVCC="nvcc"

if test -n "$with_cuda"
then
  CUDA_INCLUDES="-I$with_cuda/include"
  CUDA_LIBS="-lcudart"
  CUDA_LDFLAGS="-L$with_cuda/lib$SUFFIX"
  if test -x "$with_cuda/bin/nvcc"
  then
    NVCC="$with_cuda/bin/nvcc"
  else
   abc="123"
  fi
else
  CUDA_INCLUDES="-I/usr/local/cuda/include"
  CUDA_LIBS="-lcudart -static-libstdc++"
  CUDA_LDFLAGS="-L/usr/local/cuda/lib$SUFFIX"
fi

if test -n "$with_nvml" ; then
  NVML_LIBPATH=$with_nvml
  CUDA_LDFLAGS="$CUDA_LDFLAGS -ldl"
fi

I was getting the same error and fixed it by adding an else statement that does nothing.
edit  I also added a then too.

You can and should if your cards are different, but if you just set it once it should use that for all cards.

Excuse me pissed off author, but when I try to compile yours on ubuntu 14.04 and cuda 6.5 and get this error


Would you be kind enough to help me figure it out?

I am mining on la1.blakecoin.com.  I started out using blakecoin algorithm and thought I would see what happens when I used the blake algorithm.  To my surprise I was getting accepted shares but with half the hash rate.  I have been running with the blakecoin now for a while, but  I swithed it back to blake now to see if I was just wrong before.  So far I have one accepted (booo) with a message that says 'h is not zero' in red.  As of the finish writing of this I still just have the one bad accepted share with blake algorithm.

Also accepts are few and far between on both of them.  So I get a pool reported hash rate that is low or 0 for a while then it spikes up when I get an accept.

This might be another easy question that I don't have the answer to yet, but how do I know to use either the blake or blakecoin algorithm?  They both seem to give me accepted shares, but one is half the hash rate of the other.  Thanks for any help again.

Epsylon3, I think you might be correct with your advise.  I thought in bed before sleeping and realized these are for the 750 ti and not my 780 gtx.  I am compiling a new one with the advice your gave me.  Thanks you.

Edit: You were spot on and it is working just fine now.  Donations sent.

I am trying to use this with Xubuntu 14.04.1, kernel 3.13.0-37, nvidia driver 340.46, cuda 6.5.  I have other versions of ccminer compiled and working.  I can compile this without error.  The problem comes when I am trying to execute ccminer.  It gives me this error message: "Cuda error in file 'blake32.cu' in line 273 : invalid device symbol."  I get the same type of 'invalid device symbol' for other algorithms too.  Could someone please help me figure out why I ma getting this error.

Well now I am waiting to see if my work was for something or nothing before I start mining on this site again.  Looked good until I woke up and had log in problems then 0's across the board for earnings once logged in, but hash rate was still there.
