cudaminer-latest-windows-build-from-source

It seems that a lot of people are having trouble figuring out how to compile CudaMiner from source for Windows and since our readers have also requested a simple and easy to use guide, we have prepared something that should help. The process is pretty simple and straight forward, so if you follow the steps you should be able to compile the code yourself in no time, probably…

First Download the required files:
– You need to have Visual Studio 2010 or 2012 with C++ installed, other versions might also work, but we have not tested.
– Download and install Nvidia CUDA Toolkit, do note that Visual Studio needs to be installed first for the CUDA Toolkit to properly work with it.
– You need to download the Windows versions of pthreads, OpenSSL and curl for the respective version you will be compiling for (32 or 64-bit), there is a complete package that contains all of these to make it simple for you, though they may not be the latest versions.
– Download the latest CudaMiner source code, use the Download ZIP button on the right to make it easier.

cudaminer-requirements

Prepare everything for compiling the project:
– Create a folder where you will place all of the required files, for example CUDAMINER-WIN and extract the complete package of prerequisites in it as well as the source code of CudaMiner, you should have things look like on the image above.
– Open the CudaMiner-master folder and open the cudaminer.sln project file, it should load up in Visual Studio. Note that the project is in VS2010 format and if using 2012 for example you will be asked to upgrade the project to the 2012 format, choose yes.

cudaminer-code-generation

Final tweaks and compiling the project in Visual studio:
– Make Sure you have selected Release build and choose if you are compiling a 32 or 64-bit version inside Visual Studio after you have opened up the cudaminer SLN file.
– If you wan to compile the code for a specific GPU architecture other than the default you will need to go to Project, Properties, Confguration Properties, CUDA C/C++, Device and select the required ones under Code Generation.
– Select Build Solution from the Build menu and wait for the compilation process to finish, you will find the executable file in the Release folder (or x64, Release for the 64-bit version).
– You need the cudaminer.exe executable file and the respective cudart DLL file (32 or 64-bit, depending on the version you are building).
– You also need to get the respective 32 or 64-bit version of the pthreadVC2.dll file from the phtreads folder.
– Put the executable file and the two DLL files in a single folder and you are ready to run CudaMiner.
– Note that on your system everything should be working fine, but on other computers lacking Visual C++ Redistributable for Visual Studio 2010/2012 installed you will need to also install this package (version depends on what version of Visual Studio you have used to compile the project). Alternatively you can just include the msvcp and msvcr DLL files along with the other files to make sure you have all of the required files packaged together.

Hopefully this guide will help you compile the CudaMiner source code for Windows on your own, this could also be helpful in compiling other projects if you haven’t used Visual Studio at all, though the guide is specifically for compiling CudaMiner.

gridseed-asic-miners-farm

Just a reminder about this week’s photo contest for a chance to win a 5-chip Gridseed ASIC miner provided by our partners GAWMiners. All you have to do is submit a photo showing the “tidiest cabling of your mining rigs” and you could get an ASIC miner as a reward this week, furthermore you could also play and win in the next two weeks of April as well by participating in the photo contest as each week there will be a different theme of the contest and another Gridseed ASIC device as a prize. So do not miss your chance this week, you still have a few more days to submit your entry.

Submit your photo contest entries here in order to get a chance to win a Gridseed ASIC miner…

kopiemtu-kubuntu-nvidia-miner-live-distro

KopiemTu is an interesting project that aims to make it easy for people with Nvidia-based video cards such as GTX 750 Ti for example to be able to start mining crypto currencies under Linux. KopiemTu is based on Kubuntu and comes in the form of a bootable image that you can put on an 8 GB or more USB flash drive and directly boot from it, no need to install it. It includes Nvidia drivers and CudaMiner compiled for Linux, so as soon as you boot it you can start mining. There is also a simple web-based monitoring service available that you can watch remotely without having to login to the Linux machine to check the status.

And while KopiemTu is not yet like BAMT or SMOS Linux mining distributions it still makes it easier for people that are not very familiar with Linux to start mining. What is kind of missing at the moment is an easy way to configure and use the live distribution without having to rely on console commands. When you start you are presented with an empty desktop and an icon only for the console, but no easy to use icons to automate the most common tasks, you still need to go to the console, switch to root user and edit a configuration file to set your pool settings (config files stored in /etc/kopiemtu/). Even a wallpaper with the most common things you need as commands or a ReadMe file on the desktop would be nice for new users.

What you need to know to get you started is that the root password is live, and you start and stop the mining by typing the “mine start” command in the console, after setting your settings in the config file for the pool you want to mine in. with “monitor start” you are activating the web-based monitoring that you can see from a web browser by typing the IP address of the system. The good thing is that since CudaMiner does support most of the crypto coins algorithms you are easily able to configure settings for different coins without having to recompile something for example. The only problem that is common under Linux and is also present here is the overclocking of the GPUs, the solution to that problem is to modify the video BIOS with the overclocked frequencies and flash it on the video card(s), so that the right settings will be applied all the time.
