Take a look at Windows Build Instructions By Matt Corallo, it's outdated, but has some additional comments to the included doc. Install: MinGW Automated Installer from http://sourceforge.net/projects/mingw/files/OldFiles/mingw-get-inst/mingw-get-inst-20110316/. Install with the C++ and MSYS options checked. Activestate Perl (for building ...

You can not connect with PuTTY as bitcoind only listens to RPC-JSON commands. Anything that can send over the HTTP(S) protocol is fine. See the JSON-RPC class for PHP. Assuming that you want bitcoind to accept remote RPC-JSON calls, you would need to setup your bitcoin.conf file like so: rpcuser = randomUsername rpcpassword = strongRandomPassword ...

-zapwallettxes removes all wallet transactions that are not in the blockchain. It can remove "stuck" transactions, although you don't need this feature in normal operations mode. Solution A) On Windows, you need to start the command line prompt (cmd.exe), go to your window search and enter "cmd" and start cmd.exe. Start bitcoin-qt with --zapwallettxes=1 C:...

I had the same problem and for me it worked to set the TERM variable to nothing directly before you execute cgminer. Like this in the cmd shell: set TERM= cgminer-nogpu.exe ........ If you set it to "" (meaning nothing) in the system settings it will use the default value "c:\windows\system32\cmd.exe". You can check the the variable in the shell with: ...

You can install the standard Bitcoin-QT client, navigate to \Program Files (x86)\bitcoin\daemon\ and then run bitcoind -gen=1 However this isn't recommended except on the Test network because it is next to impossible to generate any coins this way on the production network.

poclbm has not been set to alter the clock rate of your GPU. Windows media player is doing this when open and adjusts the system to what it requires. If you specify clock speeds for your GPU via parameters or a separate application you can overcome this. Theres a number of applications which effect clock rates on windows machines, flash player open within ...

This is a common problem whose cause is not well known. You can try switching miners, switching flags, or switching OpenCL versions. Usually you can find a combination that resolves the problem. I've seen this question asked several times and I've not yet seen a solid answer.

When looking at the Bitcoin Developer Reference I saw an example where they use two additional '' before and after the list of inputs in comparison to you. For your input, I also got "Error parsing JSON", but with bitcoin-cli -testnet createrawtransaction '''[{ "txid" : "12b8e7ede4992f4d30f93idj3085746951d945e39f40becebd7c290af8c2e7ad", "vout" : 0 }]''' '{"...

You can find the blockchain in this directory: C:\Documents and Settings\YourUserName\Application data\Bitcoin (XP) or C:\Users\YourUserName\Appdata\Roaming\Bitcoin (Vista and 7) As blk0001.dat and blkindex.dat. Copying those files to a proper folder on your Ubundu (~/.bitcoin/) should spare you from redownloading the entire blockchain.

They're in the wallet.dat file.

You're getting this error because bitcoind isn't running. Once it is, it will create an authentication cookie, and bitcoin-cli will be able to connect. To start bitcoind from cmd prompt, type: cd C:/Program\ Files/Bitcoin/daemon/ Press enter, then type: bitcoind And press enter.

What are you expecting it to do? It is a daemon (server) that is waiting for RPC connections on port 8333. Your bitcoin.conf needs to have configured the rpcuser and rpcpassword. Then you can access the bitcoin API. With Bitcoin-Qt version 0.7 and higher, the Debug window gives you access to run a console, so you don't need to run bitcoind if you are ...

I believe the blame lies on AMD's driver. I've heard that 11.9 might have fixed the bug, but am not sure. 11.6 works for me on Debian Squeeze without the cpu usage bug.

The build_unix directory contains just the .IGNORE_ME file in the distribution. The directory is populated by the make command. ../dist/configure --disable-replication --enable-mingw --enable-cxx make You do not need to edit db.h in the latest distribution since they have already corrected the typedef.

These executables are used to run Bitcoin's unit tests, so that developers can verify that various parts of the code work as designed. They are not needed by end users. From the file src/test/README.md: The sources in this directory are unit test cases. Boost includes a unit testing framework, and since bitcoin already uses boost, it makes sense to ...

Try rewriting your command to bitcoin-cli -testnet createrawtransaction "[{\"txid\": \"12b8e7ede4992f4d30f93idj3085746951d945e39f40becebd7c290af8c2e7ad\", \"vout\": 0}]" "{\"mxh3H416KCRoBDiweSESew5YJyAk1nxLrN\": 0.025, \"mkrzDhhZtzQm8zgckSs4fMNrvtNJ66zaFe\": 0.0245}" as suggested by this thread.

You can run bitcoind.exe on windows if you leave off the -daemon flag, as the error message says. Then it will run in the command prompt window or whatever you are running it with. While it's running, you can interact with it using bitcoin-cli.exe in a separate command prompt window. No, you can't run bitcoind and bitcoin-qt at the same time if they're ...

bitcoin data dir link in the wiki: https://en.bitcoin.it/wiki/Data_directory ... shows where all the data files are located, the "a proper folder" link from ThePiachu 's post seems to have died since.

AMD Catalyst drivers have a bug which result in 100% CPU usage. The current drivers (11.9 as of writing) solve this bug for SINGLE GPU systems but MULTIPLE GPU systems are still affected by the "100% CPU bug". This isn't anything that can be fixed in software it must be fixed by AMD driver team. The 11.10 preview driver also doesn't (at time of writing) ...

BitcoinSpinner for Android phones allows you to export your private key in the Sipa format. This allows you to import it in any wallet service that supports Sipa formatted private keys.

You can use online wallet, like StrongCoin, then it doesn't matter where you access it from. You need to use an Android client that allows for private key import/export. I'm not sure which Android client does this, but for Windows/Linux you either can look for some tools for altering the wallet.dat for the standard Client, or use an alternative client with ...

The Linux installer is slightly different to the windows installer in that there are different scripts to get the host machine to recognise the bitcoin URIs. What ARE very similar is the multibit-exe.jar (used on Linux and Mac) and the multibit.exe (used in Windows). The exe is basically a wrapped jar file. On any operating system you can run MultiBit jar ...

When I've had this happen it's been because of a non-clean shutdown. Something about the disk state ends up being inconsistent and this (understandably) results in the system wanting to verify all the information it has on disk.

One of the best for both LiteCoins and BTC is CGminer It supports both Linux & Windows Download from here https://github.com/ycros/cgminer/downloads You can get complete instructions from https://bitcointalk.org/index.php?topic=28402.0 Or just check the readme including in the zip It Supports FGPA GPU and GPU for BTC & GPU for LiteCoins....

By using process of elimination , I would do something like this. First, I would reinstall your Bitcoin wallet and see if it works. If it works properly, there was probably a Bitcoind configuration file that was messed around with in your original installation or you were using an outdated version. If it still doesn't work, install a Bitcoin wallet on ...

cgminer's FPGA and ASIC support was originally taken from BFGMiner. Due to the maintainers of GPU mining being upset over the obsoletion of GPU mining, they forked the project and eventually (poorly) rewrote the FPGA/ASIC drivers. You are seeing the effects of that. BFGMiner continues to maintain the original (working) drivers, but you will need to remove ...

Start the cgminer script with the -T flag. That worked for me. It disables ncurses and uses text-only output.

Place to start - use the linux "file" command, which will show the following for a bitcoin wallet (at least in the client I use) wallet.dat: Berkeley DB (Btree, version 9, native byte-order) So - you could run something like: find / -type f exec file '{U}' \; | grep "Berkeley DB" That would be a start!
