25 sudo apt-get install build-essential
26 sudo apt-get install libgtk2.0-dev
27 sudo apt-get install libssl-dev
28 sudo apt-get install libdb4.8-dev
29 sudo apt-get install libdb4.8++-dev
30 Boost 1.40+: sudo apt-get install libboost-all-dev
31 or Boost 1.37: sudo apt-get install libboost1.37-dev
33 If using Boost 1.37, append -mt to the boost libraries in the makefile.
35 Requires wxWidgets 2.9.0 or greater, which uses UTF-8. Don't try 2.8, it
38 You need to download wxWidgets from http://www.wxwidgets.org/downloads/
39 and build it yourself. See the build instructions and configure parameters
42 Requires miniupnpc for UPnP port mapping. It can be downloaded from
43 http://miniupnp.tuxfamily.org/files/. UPnP support is compiled in and
44 turned off by default. Set USE_UPNP to a different value to control this:
45 USE_UPNP= no UPnP support, miniupnp not required;
46 USE_UPNP=0 (the default) UPnP support turned off by default at runtime;
47 USE_UPNP=1 UPnP support turned on by default at runtime.
49 Licenses of statically linked libraries:
50 wxWidgets LGPL 2.1 with very liberal exceptions
51 Berkeley DB New BSD license with additional requirement that linked software must be free open source
52 Boost MIT-like license
53 miniupnpc New (3-clause) BSD license
55 Versions used in this release:
66 The UI layout is edited with wxFormBuilder. The project file is
67 uiproject.fbp. It generates uibase.cpp and uibase.h, which define base
68 classes that do the rote work of constructing all the UI elements.
70 The release is built with GCC and then "strip bitcoin" to strip the debug
71 symbols, which reduces the executable size by about 90%.

99 You need Berkeley DB 4.8. If you have to build Berkeley DB yourself:

114 To help make your bitcoin installation more secure by making certain attacks impossible to
115 exploit even if a vulnerability is found, you can take the following measures:
117 * Position Independent Executable
118 Build position independent code to take advantage of Address Space Layout Randomization
119 offered by some kernels. An attacker who is able to cause execution of code at an arbitrary
120 memory location is thwarted if he doesn't know where anything useful is located.
121 The stack and heap are randomly located by default but this allows the code section to be
122 randomly located as well.
124 On an Amd64 processor where a library was not compiled with -fPIC, this will cause an error
125 such as: "relocation R_X86_64_32 against `......' can not be used when making a shared object;"
127 To build with PIE, use:
128 make -f makefile.unix ... -e PIE=1
130 To test that you have built PIE executable, install scanelf, part of paxutils, and use:
133 The output should contain:
137 * Non-executable Stack
138 If the stack is executable then trivial stack based buffer overflow exploits are possible if
139 vulnerable buffers are found. By default, bitcoin should be built with a non-executable stack
140 but if one of the libraries it uses asks for an executable stack or someone makes a mistake
141 and uses a compiler extension which requires an executable stack, it will silently build an
142 executable without the non-executable stack protection.
144 To verify that the stack is non-executable after compiling use:
147 the output should contain:
151 The STK RW- means that the stack is readable and writeable but not executable.
