Topic: Coin making guides (Read 6503 times)

Ok, I figured it out I think.

So here now is what I have, I have CXX in a build folder of the Wallet, Boostrapped, all Libraries, all Paths, I have the PATH set to the Cmake Bin so I can >cmake.exe and I have the Submodule of the Coin in the Wallet src folder and I am getting Qt 5.9 right now

1.3. Ensure that mingw-builds bin folder is set in your PATH environment variable. On Windows 7 your path should look something like:

Hi all, I recently went through the process of building bitcoind on windows.
I found the official build-msw.txt to be a bit lacking, so I thought that documenting the steps here on the forums could save some time to people wanting to compile their own windows binary. Wink

Please note this is mostly for testing purposes. Always use official executables on production environments.
The following instructions are intended for use with version 0.9.4. See additional notes if compiling 0.10rc4 or an older 0.8.6 branch.

1. Prepare your build system.
I strongly suggest setting up a clean windows virtual machine via Virtualbox or similar.

1.1 Install msys shell:
http[Suspicious link removed]/download
From MinGW installation manager -> All packages -> MSYS
mark the following for installation:

msys-base-bin
msys-autoconf-bin
msys-automake-bin
msys-libtool-bin

then click on Installation -> Apply changes

Make sure no mingw packages are checked for installation or present from a previous install. Only the above msys packages should be installed. Also make sure that msys-gcc and msys-w32api packages are not installed.

1.2 Install MinGW-builds project toolchain:
Download http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/4.9.2/threads-posix/dwarf/i686-4.9.2-release-posix-dwarf-rt_v3-rev1.7z/download
and unpack it to C:\

1.3. Ensure that mingw-builds bin folder is set in your PATH environment variable. On Windows 7 your path should look something like:

1.4 Additional checks:
C:\MinGW\bin should contain nothing but mingw-get.exe.
Your gcc -v output should be:

2. Download, unpack and build required dependencies.
I'll save them in c:\deps folder.

2.1 OpenSSL: http://www.openssl.org/source/openssl-1.0.1l.tar.gz
From a MinGw shell (C:\MinGW\msys\1.0\msys.bat), unpack the source archive with tar (this will avoid symlink issues) then configure and make:

2.2 Berkeley DB: http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz
We'll use version 4.8 to preserve binary wallet compatibility.
From a MinGW shell unpack the source archive, configure and make:

2.3 Boost: http://sourceforge.net/projects/boost/files/boost/1.57.0/
Download either the zip or the 7z archive, unpack boost inside your C:\deps folder, then bootstrap and compile from a Windows command prompt:

This will compile the required boost libraries and put them into the stage folder (C:\deps\boost_1_57_0\stage).
Note: make sure you don't use tarballs, as unix EOL markers can break batch files.

2.4 Miniupnpc: http://miniupnp.free.fr/files/download.php?file=miniupnpc-1.9.20150206.tar.gz
Unpack Miniupnpc to C:\deps, rename containing folder from "miniupnpc-1.9.20150206" to "miniupnpc" then from a Windows command prompt:

2.5 protoc and libprotobuf:
Download https://github.com/google/protobuf/releases/download/v2.6.1/protobuf-2.6.1.tar.gz
Then from msys shell

2.6 qrencode:
Download and unpack http://download.sourceforge.net/libpng/libpng-1.6.16.tar.gz inside your deps folder then configure and make:

Download and unpack http://fukuchi.org/works/qrencode/qrencode-3.4.4.tar.gz inside your deps folder then configure and make:

2.7 Qt 5 libraries:
Qt must be configured with ssl and zlib support.
Download and unpack Qt base and tools sources:
http://download.qt-project.org/official_releases/qt/5.3/5.3.2/submodules/qtbase-opensource-src-5.3.2.7z
http://download.qt-project.org/official_releases/qt/5.3/5.3.2/submodules/qttools-opensource-src-5.3.2.7z
Then from a windows command prompt (note that the following assumes qtbase has been unpacked to C:\Qt\5.3.2 and qttools have been unpacked to C:\Qt\qttools-opensource-src-5.3.2):

Note: consider using -j switch with mingw32-make to speed up compilation process. On a quad core -j4 or -j5 should give the best results.


3. Download and unpack Bitcoin 0.9.4 from git https://github.com/bitcoin/bitcoin/archive/v0.9.4.zip

From msys shell configure and make bitcoin:

Additional notes:
64 bit binaries
64 bit binaries can be compiled by using the following toolchain:
http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/4.9.2/threads-posix/seh/x86_64-4.9.2-release-posix-seh-rt_v3-rev1.7z/download

All dependencies must be rebuilt with the above toolchain.
Openssl should be configured for:
instead of:

Bitcoin v0.10rc4
Since v0.10 Bitcoin depends on gmp: https://gmplib.org/download/gmp/gmp-6.0.0a.tar.xz
Compile it in a msys shell


Then add relevant CPPFLAGS and LDFLAGS when configuring Bitcoin:

ompiling with unit tests
In order to build unit tests you will need the following:
-boost
Boost must be configured with --with-test option also.

-hexdump
To generate test data an hexdump like program is needed.
Download and unpack https://github.com/wahern/hexdump then compile hexdump.exe by running:

Do not forget to add hexdump folder to your PATH environment variable.

-bitcoin
In order to work with the previously compiled hexdump version Makefile must be patched (src/Makefile.test.include if v0.10, src/Makefile.include if v0.9):

bitcoin must be configured without --disable-tests option.






Additional notes for older Bitcoin 0.8.6 (may be useful for Bitcoin based altcoins)
msys-autoconf, msys-automake and msys-libtool at step 1.1 are not needed. You can skip steps 2.5 and 2.7.
Note that openssl v1.0.1k and later may lead to consesus forks:
http://sourceforge.net/p/bitcoin/mailman/message/33221963/

Compile bitcoind 0.8.6: https://github.com/bitcoin/bitcoin/archive/v0.8.6.zip

With a texteditor edit BOOST_SUFFIX, INCLUDEPATHS and LIBPATHS in your C:\bitcoin-0.8.6\src\makefile.mingw according to your dependencies location:

and add -static option to LDFLAGS in makefile.mingw to compile a statically linked executable.

makefile.mingw patch:

Upnp support is disabled by default. If you want to compile with upnp support set

and add miniupnpc path to INCLUDEPATHS and LIBPATHS:

From Msys shell compile bitcoind:

Compile bitcoin-qt 0.8.6 with Qt 4.8:
Download and unpack http://download.qt-project.org/official_releases/qt/4.8/4.8.6/qt-everywhere-opensource-src-4.8.6.zip
Note that due to a bug in qt 4.8.6 you will need to explicitly enable windows styles: https://bugreports.qt-project.org/browse/QTBUG-38706
Assuming qt sources have been unpacked to C:\Qt\4.8.6, from a windows command prompt:

Note that if you skipped bitcoind compilation or if you have cleaned up your source folder you will need to compile libleveldb.a and libmemenv.a libraries before proceeding.
From msys shell:

Comment out genleveldb.commands for win32

flags for static build:


bitcoin-qt.pro patch:


From a windows command prompt configure and make:

This guide outlines the steps to manually generate a genesis block and start a new blockchain. Once the genesis block is generated, two nodes must be used to start the blockchain. This guide will show you how to do this on one machine, using two data directories and two instances of the daemon. Please note that it is also possible to do this using two physical or virtual machines.
Install Dependencies and Mini-UPnP

If Peershares has never been run on your machine, be sure to follow the Dependency and Mini-UPnP installation steps, located on the Linux wiki page: https://github.com/Peershares/Peershares/wiki/Linux
Clean-up Prior Work

If you have already been using your machine to test Peershares builds, it's a good idea to delete your prior working folders and start fresh.

$ rm -r ~/.peershares
$ rm -r ~/Peershares

Clone the Peershares Github Repository

$ git clone https://github.com/Peershares/Peershares.git

Get the current unix epoch time from the command line, or, from using a site like Epoch Converter.

$ date +%s

We'll use this in a few minutes, so copy it down.
Edit main.cpp

$ cd ~/Peershares/src/
$ (text editor) main.cpp

Be sure to turn on line numbering in your text editor. Edit the following lines ...

Main.cpp:L2260 - Change the value for the constant, pszTimestamp, to something unique, up to 91 characters:

const char* pszTimestamp = "YOUR CUSTOM, VERIFIABLE TIMESTAMP GOES HERE";

Main.cpp:L2261 - Change nTimeGenesis value to current epoch time (captured in the previous step). For example, when this guide was written, the epoch time was 1395169964, so it would be inserted as so:

unsigned int nTimeGenesis=1395169964;

Main.cpp:L2262 - Make sure that nNonceGenesis=0

Main.cpp:L2266 - For the TestNet genesis block, change the value for the constant, pszTimestamp, to something unique (same length rules apply as the previous timestamp string):

Main.cpp:L2267 - Change nTimeGenesis value to current epoch time stamp. This can match the value you used for the previous nTimeGenesis variable, or you can use the epoch time for when you modified this step, either is appropriate.

Main.cpp:L2268 - Make sure that nNonceGenesis=0

Complete set of changes from the previous steps:

if (fTestNet)
  {
    pszTimestamp="YOUR CUSTOM, VERIFIABLE TESTNET TIMESTAMP GOES HERE";
    nTimeGenesis=1395170250;
    nNonceGenesis=0;
  }

Save the file and exit.
Compile the daemon

$ make -f makefile.unix

Run the daemon

$ ./peersharesd --daemon

It should start and run for a few seconds then stop with an error. This error is our notification that the new genesis block has been generated. That was for real-net. Now lets generate one for testnet.

$ ./peersharesd --daemon -testnet

It will start and run for a few seconds then stop with an error like the first one. We now have two debug.log files located at: ~/.peershares/debug.log and ~/.peershares/testnet/debug.log. You will find an entry in both of these files starting with 'PPCoin Found Genesis Block:'. Under that entry, you will find values for 'genesis hash=', 'merkle root=' and 'nNonce=' ... We need those three values from both real-net and testnet debug.log files.
Edit main.cpp and kernel.cpp

$ cd ~/Peershares/src/
$ (text editor) main.cpp

Edit the following lines ...

Main.cpp:L24 - Change the value for the constant, hashGenesisBlockOfficial, to the new genesis hash value from debug.log. Paste the value in-between the quotation marks, after the leading 0x :

static const uint256 hashGenesisBlockOfficial("0x00000053229d58cdda911f4188240d4843f6bca1d8978d3349d87c38976463dd");

Main.cpp:L25 - Change the value for the constant, hashGenesisBlockTestNet, to the new genesis hash value from TestNet debug.log. Paste the value in-between the quotation marks, after the leading 0x :

static const uint256 hashGenesisBlockTestNet ("0x00000053229d58cdda911f4188240d4843f6bca1d8978d3349d87c38976463dd");

Main.cpp:L2262 - Change the value for nNonceGenesis to the new nNonce value from debug.log:

unsigned int nNonceGenesis=236800;

Main.cpp:L2268 - Change the value for nNonceGenesis to the new nNonce value from the TestNet debug.log:

unsigned int nNonceGenesis=236800;

Main.cpp:L2312 - Change the value for block.hashMerkleRoot == uint256, to the new merkle root hash value from debug.log. Paste the value in-between the quotation marks, after the leading 0x :

assert(block.hashMerkleRoot == uint256("0xf0e9ac2cef9820c036e397c738ae5cea91df3724f5418eb6a7450350f2702278"));

Main.cpp:L2314 - Change the value for block.hashMerkleRoot == uint256, to the new merkle root hash value from TestNet debug.log. Paste the value in-between the quotation marks, after the leading 0x :

assert(block.hashMerkleRoot == uint256("0xf0e9ac2cef9820c036e397c738ae5cea91df3724f5418eb6a7450350f2702278"));

Save and exit main.cpp ... Open kernel.cpp:

$ (text editor) kernel.cpp

nProtocolV03SwitchTime and nProtocolV03TestSwitchTime need to be set to a time in the future, after PoS starts. So just set these to several days in advance. Use the Epoch Converter to get the correct value.

Kernel.cpp:L14 - Change the value for nProtocolV03SwitchTime to the to the correct future time. Edit the number after the '=' sign and update the comment to reflect what it was changed to:

unsigned int nProtocolV03SwitchTime     = 1394841600; // 2014-03-15 00:00:00 UTC

Kernel.cpp:L15 - Change the value for nProtocolV03TestSwitchTime to the to the correct future time. Edit the number after the '=' sign and update the comment to reflect what it was changed to:

unsigned int nProtocolV03TestSwitchTime = 1396224000; // 2014-03-31 00:00:00 UTC

Save and exit kernel.cpp
Recompile the daemon

$ make -f makefile.unix BDB_INCLUDE_PATH="/usr/local/BerkeleyDB.4.8/include" BDB_LIB_PATH="/usr/local/BerkeleyDB.4.8/lib"

Remove and recreate working folder

Add a 2nd working folder for instance2, which is needed to start the blockchain.

$ rm -r ~/.peershares/
$ mkdir ~/.peershares/
$ mkdir ~/.peershares2/

Move the newly recompiled daemon to working folder

$ mv ppcoind ~/.peershares

Create conf file and start instance 1

$ cd ~/.peershares
$ touch peershares.conf
$ (text editor) peershares.conf

Add the following lines to the conf file and save:

server=1
rpcallowip=127.0.0.1
listen=1
rpcuser=
rpcpassword=
dnsseed=0
port=9090
rpcport=9091
gen=1

Run the daemon

$ ./ppcoind --daemon

If it stops with an error about blkindex.dat when it is run for the first time, simply run it again and it should work. This is a known issue on the first run attempt.
Copy and rename daemon to 2nd instance

$ cp ppcoind ~/.peershares2/ppcoind2

Create conf file for 2nd instance

$ cd ~/.peershares2
$ touch peershares.conf
$ (text editor) peershares.conf

Add the following lines to the conf file and save:

server=1
rpcuser=
rpcpassword=
port=19090
rpcport=19091
gen=1

Run the 2nd instance of the daemon

We must specify the data directory so that the 2nd instance doesn't try to use '~/.peershares' and we must also specify that we want to connect to the IP address of our first instance, which, in this case, is localhost. Be sure to replace with your username. Note that datadir and connect commands can be added to your conf file to simplify things.

$ ./ppcoind2 --daemon -datadir=/home//.peershares2 -connect=127.0.0.1:9090

If either instance stops with an error about blkindex.dat when it is run for the first time, kill the instance and run again with the same command. It should work on the 2nd try. This is a known issue.

At this point, your new blockchain should be started and both instances should be generating PoW blocks. Check status with:

$ ./ppcoind getinfo
$ ./ppcoind getmininginfo
$ (text editor) debug.log

Or from the 2nd instance dir

$ ./ppcoind2 getinfo
$ ./ppcoind2 getmininginfo

If you wish to start a testnet, add testnet=1 to your conf files, stop and restart the daemons.

Note: If difficulty settings are changed in Main.cpp:L37 and Main.cpp:L38, you'll need to recreate the genesis block because the nonce/hash/merkel root will change.

Great guide, keep it up!

This is very nice, I'm sure a lot of people will benefit from your compiled list because it is so complete.

But it's not all about creating the coin, it's about promoting as well.

You should add more about promoting and selling the actual altcoin. You want people to start using your coin.

Anyways, it's a great list, love it!

I'm sure you took a lot of time just to compile this coin and it's worth it,users will bookmark or copy your works ,thanks for taking the time I seldom see a compilation thread in this section and your work is worth it.

Thanks. This is a great guide, this thread is going to help a lot of people.

Here's a complete guide on creating genesis block, how to edit the source code and control the network: http://www.theseus.fi/bitstream/handle/10024/123896/Sikorski_Timothy.pdf?sequence=1

is good information and complete information
what is youre recomended create altcoin is easy and good quality
walletbuilders is not recomended because altcoin user not interest coin if develop use walletbuilders
