-miniupnpc may be used for UPnP port mapping. It can be downloaded from
-http://miniupnp.tuxfamily.org/files/. UPnP support is compiled in and
-turned off by default. Set USE_UPNP to a different value to control this:
- USE_UPNP= No UPnP support - miniupnp not required
- USE_UPNP=0 (the default) UPnP support turned off by default at runtime
- USE_UPNP=1 UPnP support turned on by default at runtime
+Note that libexecinfo should be installed, if you building under *BSD systems.
+This library provides backtrace facility.

+libqrencode is used for QRCode image generation. It can be downloaded

Dependency Build Instructions: Ubuntu & Debian
----------------------------------------------
sudo apt-get install libdb4.8++-dev
Boost 1.40+: sudo apt-get install libboost-all-dev
or Boost 1.37: sudo apt-get install libboost1.37-dev
+sudo apt-get install libqrencode-dev
If using Boost 1.37, append -mt to the boost libraries in the makefile.
Dependency Build Instructions: Gentoo
-------------------------------------
-emerge -av net-libs/miniupnpc boost openssl sys-libs/db
-Then take the following steps to build:
- cd ${BITCOIN_DIR}/src
- sed -i 's/<db_cxx.h>/<db4.8\/db_cxx.h>/' *.h # path fix
- sed -i 's/-Bstatic/-Bdynamic/' makefile.unix # dynamic linking
- sed -i 's/^USE_UPNP:=0$/USE_UPNP:=/' makefile.unix # disable UPnP
- make -f makefile.unix
- strip bitcoind
+Note: If you just want to install novacoind on Gentoo, you can add the Novacoin
+ overlay and use your package manager:
+ layman -a novacoin && emerge novacoind
+
+emerge -av1 --noreplace boost glib openssl sys-libs/db:4.8
+
+Take the following steps to build:
+ cd ${NOVACOIN_DIR}/src
+ make -f makefile.unix BDB_INCLUDE_PATH='/usr/include/db4.8'
+ strip novacoind

+To help make your novacoin 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
make -f makefile.unix ... -e PIE=1
To test that you have built PIE executable, install scanelf, part of paxutils, and use:
- scanelf -e ./bitcoin
+ scanelf -e ./novacoin
The output should contain:

+ vulnerable buffers are found. By default, novacoin 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 ./bitcoin
+ scanelf -e ./novacoin
the output should contain:
