ethminer-0.9.41-genoil-1.1

[Genoil]

Hi all, is there any chance soon someone to build ethereum miner for Win32 ? I already compiled  ethminer-0.9.41-genoil on win64 and it is great, but i am curious if it is possible for win32?!
Thanks in advance!

It can be done and some devs have tried, but it's not quite straightforward. So I guess that's a no.

[tolazy]

sorry for asking so much Genoli..
i dont know why.

For some reason it looks like ETH_STRATUM is not defined, while cmake should have defined it. What you could try is remove #if ETH_STRATUM || !ETH_TRUE from Mineraux at the top of the file (and the #endif, but not the include in between)

How much performance improvements this miner has, if we compare with the original cuda miner?

[Genoil]

This is the original CUDA ethminer. Performance-wise it is about 10-40% faster (depending on GPU) compared to the official OpenCL miner when using the same hardware.

CBUCHNER--

Because CBuchner started using CUDA code in CudaMiner and CCminer, many miners have confused Genoil's Ethminer with older cryptocoin mining software.  Genoil's Ethminer is a CUDA-enabled piece of mining software that mines DAGGER-Hashimoto coins.  Comparing it to the earlier CUDA mining software is like comparing "apples and oranges".  They don't mine the same algorithms.    --scryptr

Dear Genoil.

Why this very usefull option doesn't work on your fork?
ethminer --list-devices

Tolazy,
This might not help you much, but I was able to build the ethminer from a fresh install of all tools within an hour.
On Xubuntu 14.04.4 LTS.

I built for AMD GPUs using this command
 cmake -DBUNDLE=miner
I had to repeat the cmake cmd a lot of times taking note of all the complaints.
Based on the cmake error messages I found I had to install the following packages (I already had the AMD driver installed):

Code:

 sudo apt-get update
 sudo apt-get upgrade
 sudo apt-get install  build-essential
 sudo apt-get install fakeroot
 sudo apt-get install dh-make
 sudo apt-get install debconf execstack dh-modaliases
 sudo apt-get install dkms
 sudo apt-get install pkg-config
 sudo apt-get install libtool
 sudo apt-get install libncurses5-dev
 sudo apt-get install libcryptopp-dev
 sudo apt-get install libleveldb-dev
 sudo apt-get install libjsoncpp-dev libargtable2-dev
 sudo apt-get install libjson-rpc-cpp-dev
 sudo apt-get install libmicrohttpd-dev
 sudo apt-get install libreadline-dev
 sudo apt-get install -f libsdl2-dev
 sudo apt-get install build-essential libtool autotools-dev automake
 sudo apt-get install pkg-config  libssl-dev libevent-dev bsdmainutils
 sudo apt-get install  qttools5-dev-tools libprotobuf-dev protobuf-compiler
 sudo apt-get install libgmp-dev
 sudo apt-get install cpuid

Some of these might not be needed for the ethminer build, but I needed them for the AMD driver. YMMV.
Once cmake is happy (no errors) you should have a Makefile.  Just run make after that.
I have
cmake version 3.2.2
gcc (Ubuntu 4.8.4-2ubuntu1~14.04.1) 4.8.4

Code:

cd ethminer
 file ethminer
ethminer: ELF 64-bit LSB  executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=8c71afcbb564055dfcbfb9968fe30ab3faf0993d, not stripped

If I were you I would unzip the ethminer to a new directory and try over.

-DBUNDLE=miner works great. it the -DBUNDLE=cudaminer i cant get to work.

Ok, I see.
I moved over to my other box with same build env, except with CUDA 7.5  instead of AMD catalyst,
then compiled it there.
cmake  -DCOMPUTE=30 -DBUNDLE=cudaminer
then installed all the packages that cmake complained about.
then ran make with out error.
nvcc --version
Built on Tue_Aug_11_14:27:32_CDT_2015
Cuda compilation tools, release 7.5, V7.5.17

I have an GTX 970 so I cannot run it since the -DCOMPUTE=30 cmake flag.

I think the reason for your problem is Ubuntu 15.10 which require other packages..

ATM I am running qtminer and using ethpool.org and am happy with that so far.
It has built in stratum so I guess performance is on par with genoils miner, which I might try later..

[tolazy]

wonder what in 15.10 that make is not work.

the normal miner compile just fine

cmake -DCOMPUTE=30 -DBUNDLE=cudaminer .. gives me

Could NOT find cpuid (missing:  CPUID_INCLUDE_DIR CPUID_LIBRARY)  but its installed

can it be that i'm on gcc-5 and cmake 3.4.1
to me it looks like something about the cuda i've tried to look on the lines to see if i can find what breaks it

sorry for spamming so much but i just want it to work.
how do i do if i want to use a diffrent gcc then the default one gcc-5 that is.

if i min directly in cpp-ethereum with cmake -DCOMPUTE=30 -DBUNDLE=cudaminer
i get this error message

it must be me doing things wrong.
i'll stay with cmake -DBUNDLE=miner .. that works with my 660ti card getting 10.4MHs witch isnt bad getting 29.4MHs on my R9 390x on windows with genolis ethminer


can it be something with cuda ? did you use export with your cuda install

[GenTarkin]

Thanks so much for coding in --opencl-devices 0 1 n    on the latest version!!!

Long awaited and very useful feature.
The stock --opencl-device option is retarded. LOL!

[Za1n]

Dear Genoil.

Why this very usefull option doesn't work on your fork?
ethminer --list-devices

Try using:  ethminer -G --list-devices and see if that helps.
