I managed to build bitcoind on arch linux after downloading the source from github, but after running bitcoind getinfo command, I am told:
"errors" : "This is a pre-release test build - use at your own risk - do not use for mining or merchant applications"
How can I remove that message and use a stable build, instead of the pre-release one I downloaded?
I assume I have to do something with the information found here: https://github.com/bitcoin/bitcoin/tags
If you got the source via git, you can checkout on the latest stable release tag, currently v0.8.1 using the git command git checkout v0.8.1.
When you did not setup git, you can simply download the source from that tag version from the webpage you suggested using either the .zip or .tar.gz link underneath the tag name. vX.X.X releases are stable ones, while the vX.X.XrcX releases are release candidates, meaning that they can still contain a few bugs.
The full procedure:
Open a terminal and clone the github repository
git clone https://github.com/bitcoin/bitcoin
then get the latest stable version, right now the command is:
git fetch
git checkout 0.11
then build bitcoin-core as ususal (install the required lib dependencies, ./autogen.sh, ./configure, make, make install)
The current development version is 11.99, you can build multiple version of bitcoin, for example a development version and a stable version to test beta features and to see if the private keys / blockchain / backups are easily loaded on the dev version, this is the json output of the getinfo bitcoin-cli command/function that lets you check the version numbers:
version: 11.9900
protocolversion: 7.0011
walletversion: 6.0000
this means we are running 0.11.99 (it means the future 0.12)
protocol version is 7.00.11
wallet version is 6
extra infos:
the current versions are also stored in JSON on the bitcoin blockchain: 91b37d9429a7e660a6b2c3352e39335e81884493dfbfbffa479b8068194e921d (transaction hash)
