UNIX BUILD NOTES
====================
Some notes on how to build Sequence in Unix.
Building requirements for Unix based Systems : 3GB
Note
---------------------
Always use absolute paths to configure and compile Sequence and the dependencies,
for example, when specifying the the path of the dependency:
../dist/configure --enable-cxx --disable-shared --with-pic --prefix=$BDB_PREFIX
Here BDB_PREFIX must absolute path - it is defined using $(pwd) which ensures
the usage of the absolute path.
To Build
---------------------
```bash
./autogen.sh
./configure
make
make install # optional
```
This will build sequence-qt as well if the dependencies are met.
Dependencies
---------------------
These dependencies are required:
Library | Purpose | Description
------------|------------------|----------------------
libssl | SSL Support | Secure communications
libboost | Boost | C++ Library
Optional dependencies:
Library | Purpose | Description
------------|------------------|----------------------
miniupnpc | UPnP Support | Firewall-jumping support
libdb4.8 | Berkeley DB | Wallet storage (only needed when wallet enabled)
qt | GUI | GUI toolkit (only needed when GUI enabled)
protobuf | Payments in GUI | Data interchange format used for payment protocol (only needed when GUI enabled)
libqrencode | QR codes in GUI | Optional for generating QR codes (only needed when GUI enabled)
For the versions used in the release, see [release-process.md](release-process.md) under *Fetch and build inputs*.
System requirements
--------------------
C++ compilers are memory-hungry. It is recommended to have at least 1 GB of
memory available when compiling Sequence. With 512MB of memory or less
compilation will take much longer due to swap thrashing.
Dependency Build Instructions: Ubuntu & Debian
----------------------------------------------
Build requirements:
sudo apt-get install git build-essential libtool autotools-dev autoconf pkg-config libssl-dev libcrypto++-dev libevent-dev
for Ubuntu 12.04 and later or Debian 7 and later libboost-all-dev has to be installed:
sudo apt-get install libboost-all-dev
db4.8 packages are available [here](https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin).
You can add the repository using the following command:
sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
Ubuntu 12.04 and later have packages for libdb5.1-dev and libdb5.1++-dev,
but using these will break binary wallet compatibility, and is not recommended.
for Debian 7 (Wheezy) and later:
The oldstable repository contains db4.8 packages.
Add the following line to /etc/apt/sources.list,
replacing [mirror] with any official debian mirror.
deb http://[mirror]/debian/ oldstable main
To enable the change run
sudo apt-get update
for other Debian & Ubuntu (with ppa):
sudo apt-get install libdb4.8-dev libdb4.8++-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 Sequence-Qt, make sure that the required packages for Qt development
are installed. Qt 5 is necessary to build the GUI.
If both Qt 4 and Qt 5 are installed, Qt 5 will be used. Pass `--with-gui=qt5` to configure to choose Qt5.
To build without GUI pass `--without-gui`.
For Qt 5 you need the following:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libcrypto++-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 sequence-qt executable will be
built by default.
Notes
-----
The release is built with GCC and then "strip sequenced" to strip the debug
symbols, which reduces the executable size by about 90%.
miniupnpc
---------
[miniupnpc](http://miniupnp.free.fr/) may be used for UPnP port mapping. It can be downloaded from [here](
http://miniupnp.tuxfamily.org/files/). 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
To build:
tar -xzvf miniupnpc-1.6.tar.gz
cd miniupnpc-1.6
make
sudo su
make install
Berkeley DB
-----------
It is recommended to use Berkeley DB 4.8. If you have to build it yourself:
```bash
SEQUENCE_ROOT=$(pwd)
# Pick some path to install BDB to, here we create a directory within the sequence directory
BDB_PREFIX="${SEQUENCE_ROOT}/db4"
mkdir -p $BDB_PREFIX
# Fetch the source and verify that it is not tampered with
wget 'http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz'
echo '12edc0df75bf9abd7f82f821795bcee50f42cb2e5f76a6a281b85732798364ef db-4.8.30.NC.tar.gz' | sha256sum -c
# -> db-4.8.30.NC.tar.gz: OK
tar -xzvf db-4.8.30.NC.tar.gz
# Build the library and install to our prefix
cd db-4.8.30.NC/build_unix/
# Note: Do a static build so that it can be embedded into the exectuable, instead of having to find a .so at runtime
../dist/configure --prefix=/usr/local --enable-cxx
make
sudo make install
# Configure Sequence to use our own-built instance of BDB
cd $SEQUENCE_ROOT
./configure (other args...) LDFLAGS="-L${BDB_PREFIX}/lib/" CPPFLAGS="-I${BDB_PREFIX}/include/"
```
**Note**: You only need Berkeley DB if the wallet is enabled (see the section *Disable-Wallet mode* below).
Boost
-----
If you need to build Boost yourself:
sudo su
./bootstrap.sh
./bjam install
Security
--------
To help make your Sequence 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 ./sequenced
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, sequence 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 ./sequenced`
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, sequence may be compiled in
disable-wallet mode with:
./configure --disable-wallet
In this case there is no dependency on Berkeley DB 4.8.
Mining is also possible in disable-wallet mode, but only using the `getblocktemplate` RPC
call not `getwork`.
Example Build Command
--------------------
Qt Wallet and Deamon, CLI version build:
./autogen.sh && ./configure --with-gui=qt5 && make
CLI and Deamon Only Buld:
./autogen.sh && ./configure --without-gui && make
