This breaks forward compatibility of old clients. You can downgrade your wallet though with "db5.1_dump wallet.dat.old | db4.8_load wallet.dat"

UNIX BUILD NOTES
Some notes on how to build Dogecoin in Unix.
To Build
./autogen.sh
./configure
make
This will build dogecoin-qt as well if the dependencies are met.
Dependencies
Library | Purpose | Description |
---|---|---|
libssl | SSL Support | Secure communications |
libdb5.1 | Berkeley DB | Wallet storage |
libboost | Boost | C++ Library |
miniupnpc | UPnP Support | Optional firewall-jumping support |
qt | GUI | GUI toolkit |
protobuf | Payments in GUI | Data interchange format used for payment protocol |
libqrencode | QR codes in GUI | Optional for generating QR codes |
miniupnpc may be used for UPnP port mapping. It can be downloaded from here. UPnP support is compiled in and turned off by default. See the configure options for upnp behavior desired:
--without-miniupnpc No UPnP support miniupnp not required
--disable-upnp-default (the default) UPnP support turned off by default at runtime
--enable-upnp-default UPnP support turned on by default at runtime
IPv6 support may be disabled by setting:
--disable-ipv6 Disable IPv6 support
Licenses of statically linked libraries: Berkeley DB New BSD license with additional requirement that linked software must be free open source Boost MIT-like license miniupnpc New (3-clause) BSD license
- Versions used in this release:
- GCC 4.3.3
- OpenSSL 1.0.1c
- Berkeley DB 5.1.29.NC
- Boost 1.55
- miniupnpc 1.6
- qt 4.8.3
- protobuf 2.5.0
- libqrencode 3.2.0
Dependency Build Instructions: Ubuntu & Debian
Build requirements:
sudo apt-get install build-essential pkg-config
sudo apt-get install libtool autotools-dev autoconf
sudo apt-get install libssl-dev
for Ubuntu 12.04 and later:
sudo apt-get install libboost-all-dev libdb5.1-dev libdb5.1++-dev
for Ubuntu 13.10: libboost1.54 will not work, remove libboost1.54-all-dev and install libboost1.53-all-dev instead.
for other Ubuntu & Debian:
sudo apt-get install libdb5.1-dev
sudo apt-get install libdb5.1++-dev
sudo apt-get install libboost1.55-all-dev
Optional:
sudo apt-get install libminiupnpc-dev (see --with-miniupnpc and --enable-upnp-default)
Dependencies for the GUI: Ubuntu & Debian
If you want to build Dogecoin-Qt, make sure that the required packages for Qt development
are installed. Either Qt 4 or Qt 5 are necessary to build the GUI.
If both Qt 4 and Qt 5 are installed, Qt 4 will be used. Pass --with-gui=qt5
to configure to choose Qt5.
To build without GUI pass --without-gui
.
To build with Qt 4 you need the following:
apt-get install libqt4-dev libprotobuf-dev protobuf-compiler
For Qt 5 you need the following:
apt-get install libqt5gui5 libqt5core5 libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev
libqrencode (optional) can be installed with:
sudo apt-get install libqrencode-dev
Once these are installed, they will be found by configure and a dogecoin-qt executable will be built by default.
Notes
The release is built with GCC and then "strip dogecoind" to strip the debug symbols, which reduces the executable size by about 90%.
miniupnpc
tar -xzvf miniupnpc-1.6.tar.gz
cd miniupnpc-1.6
make
sudo su
make install
Berkeley DB
You need Berkeley DB 5.1. If you have to build Berkeley DB yourself:
cd build_unix/
../dist/configure --enable-cxx
make
sudo make install
Boost
If you need to build Boost yourself:
sudo su
./bootstrap.sh
./bjam install
Dependency Build Instructions: Fedora
Tested on Fedora 20:
sudo yum install autoconf automake make gcc-c++
sudo yum install openssl-devel
sudo yum install miniupnpc-devel
sudo yum install boost-devel
sudo yum install libdb-cxx-devel
sudo yum install libss-devel
sudo yum install qrencode
Optional:
sudo yum install miniupnpc-devel (see USE_UPNP compile flag)
Security
To help make your bitcoin installation more secure by making certain attacks impossible to exploit even if a vulnerability is found, binaries are hardened by default. This can be disabled with:
Hardening Flags:
./configure --enable-hardening
./configure --disable-hardening
Hardening enables the following features:
-
Position Independent Executable Build position independent code to take advantage of Address Space Layout Randomization offered by some kernels. An attacker who is able to cause execution of code at an arbitrary memory location is thwarted if he doesn't know where anything useful is located. The stack and heap are randomly located by default but this allows the code section to be randomly located as well.
On an Amd64 processor where a library was not compiled with -fPIC, this will cause an error such as: "relocation R_X86_64_32 against `......' can not be used when making a shared object;"
To test that you have built PIE executable, install scanelf, part of paxutils, and use:
scanelf -e ./dogecoin
The output should contain: TYPE ET_DYN
-
Non-executable Stack If the stack is executable then trivial stack based buffer overflow exploits are possible if vulnerable buffers are found. By default, bitcoin should be built with a non-executable stack but if one of the libraries it uses asks for an executable stack or someone makes a mistake and uses a compiler extension which requires an executable stack, it will silently build an executable without the non-executable stack protection.
To verify that the stack is non-executable after compiling use:
scanelf -e ./dogecoin
the output should contain: STK/REL/PTL RW- R-- RW-
The STK RW- means that the stack is readable and writeable but not executable.
Disable-wallet mode
When the intention is to run only a P2P node without a wallet, bitcoin may be compiled in disable-wallet mode with:
./configure --disable-wallet
In this case there is no dependency on Berkeley DB 5.1.
Mining is also possible in disable-wallet mode, but only using the getblocktemplate
RPC
