18 make -f makefile.unix # Bitcoin with wxWidgets GUI

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 2.9.1 or newer.
37 You need to download wxWidgets from http://www.wxwidgets.org/downloads/
38 and build it yourself. See the build instructions and configure parameters
41 Requires miniupnpc for UPnP port mapping. It can be downloaded from
42 http://miniupnp.tuxfamily.org/files/. UPnP support is compiled in and
43 turned off by default. Set USE_UPNP to a different value to control this:
44 USE_UPNP= no UPnP support, miniupnp not required;
45 USE_UPNP=0 (the default) UPnP support turned off by default at runtime;
46 USE_UPNP=1 UPnP support turned on by default at runtime.
48 Licenses of statically linked libraries:
49 wxWidgets LGPL 2.1 with very liberal exceptions
50 Berkeley DB New BSD license with additional requirement that linked software must be free open source
51 Boost MIT-like license
52 miniupnpc New (3-clause) BSD license
54 Versions used in this release:
65 The UI layout is edited with wxFormBuilder. The project file is
66 uiproject.fbp. It generates uibase.cpp and uibase.h, which define base
67 classes that do the rote work of constructing all the UI elements.
69 The release is built with GCC and then "strip bitcoin" to strip the debug
70 symbols, which reduces the executable size by about 90%.

80 ../configure --with-gtk --enable-debug --disable-shared --enable-monolithic --without-libpng --disable-svg
89 tar -xzvf miniupnpc-1.6.tar.gz
98 You need Berkeley DB 4.8. If you have to build Berkeley DB yourself:

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