-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 ...

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 }]''' '{"...

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'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 ...

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 ...

For the first command, you need to include the JSON in single quotes, like so: $ bitcoin-cli createrawtransaction '[{"txid":"dbdc2e2c7f143af70c5e7e8725f55d226b3c058d7bf34a303091b3c6a514848c","vout":1}]' '{"1BCi1L25GC9hUSvtSyGjmEvSyywoYubk4P":0.00011}' ...

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 ...

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.

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.

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 ...

The blocks, chains, and all that excessive data can be tossed. All you need is your wallet.dat which contains your private key. I like to think of it this way... The bitcoin network is like a massive bank full of billions, trillions, and so on of vaults. You can put coins into any vault without needing a key to that vault. You can only take coins out of a ...

CPU and GPU mining costs more in electricity than it rewards in BTC at the moment. You need special equipment with ASIC chips to mine at a profit. These chips are designed to perform many hashes at low power consumption. I suggest you ask your boss if he agrees with the negative efficiency of your current setup.

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!

While you have bitcoind or bitcoin-qt running with the -server option, you can then use bitcoin-cli to run commands. It's part of the bitcoind package. If you have your conf file in a custom directory you'll have to specify that to bitcoin-cli as well, otherwise it should just work.
