UNIX BUILD NOTES

Dependencies

These dependencies are required:

Library Purpose Description
libssl1.0 Crypto Random Number Generation
libgmp Secp256k1 Secp256k1 Dependency
libboost Utility Library for threading, data structures, etc
libevent Networking OS independent asynchronous networking
libdb4.8 Berkeley DB Wallet storage (only needed when wallet enabled)
libsecp256k1 Secp256k1 Elliptic Curve Cryptography

Optional dependencies:

Library Purpose Description
miniupnpc UPnP Support Firewall-jumping support
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 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 MarteX Core. 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 build-essential libtool automake autotools-dev autoconf pkg-config libssl1.0-dev libboost-all-dev libgmp3-dev libevent-dev bsdmainutils zlib1g-dev

On at least Ubuntu 14.04+ and Debian 7+ there are generic names for the individual boost development packages, so the following can be used to only install necessary parts of boost:

sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev

If that doesn't work, you can install all boost development packages with:

sudo apt-get install libboost-all-dev

BerkeleyDB is required for the wallet. db4.8 packages are available here. You can add the repository and install using the following commands:

sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install libdb4.8-dev libdb4.8++-dev

Ubuntu and Debian have their own libdb-dev and libdb++-dev packages, but these will install BerkeleyDB 5.1 or later, which break binary wallet compatibility with the distributed executables which are based on BerkeleyDB 4.8. If you do not care about wallet compatibility, pass --with-incompatible-bdb to configure.

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 MarteX-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.

To build with Qt 5 (recommended) you need the following:

sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler

libqrencode (optional) can be installed with:

sudo apt-get install libqrencode-dev

Once these are installed, they will be found by configure and a MarteX-qt executable will be built by default.

Berkeley DB

It is recommended to use Berkeley DB 4.8. If you have to build it yourself:

MarteX_ROOT=$(pwd)

# Pick some path to install BDB to, here we create a directory within the MarteX directory
BDB_PREFIX="${MarteX_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 executable, instead of having to find a .so at runtime
../dist/configure --enable-cxx --disable-shared --with-pic --prefix=$BDB_PREFIX
make install

# Configure MarteX Core to use our own-built instance of BDB
cd $MarteX_ROOT
./autogen.sh
./configure LDFLAGS="-L${BDB_PREFIX}/lib/" CPPFLAGS="-I${BDB_PREFIX}/include/" # (other args...)

Notes

  1. You only need Berkeley DB if the wallet is enabled (see the section Disable-Wallet mode below).

  2. The release is built with GCC and then "strip MarteXd" to strip the debug symbols, which reduces the executable size by about 90%.

To Build MarteXd

With UPNP:

cd src && \
make -f makefile.unix && \
strip MarteXd

(Recommended) Without UPNP:

cd src && \
make -f makefile.unix USE_UPNP= && \
strip MarteXd

To Build MarteX-QT

With UPNP: qmake -qt=qt5 &&
make \

(Recommended) Without UPNP:

qmake -qt=qt5 USE_UPNP=- && \
make \

Boost

If you need to build Boost yourself:

sudo su
./bootstrap.sh
./bjam install

Upnp

If you need to build miniupnpc yourself:

tar -xzvf miniupnpc-1.6.tar.gz
cd miniupnpc-1.6
make
sudo su
make install

Security

To help make your MarteX installation more secure by making certain attacks impossible to exploit even if a vulnerability is found, you can take the following measures:

  • 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 build with PIE, use: make -f makefile.unix ... -e PIE=1

    To test that you have built PIE executable, install scanelf, part of paxutils, and use: scanelf -e ./MarteX

    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, MarteX 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 ./MarteX

    the output should contain: STK/REL/PTL RW- R-- RW-

    The STK RW- means that the stack is readable and writeable but not executable.
