Building libtorrent - gazpachoking/deluge GitHub Wiki

This page is for edge cases where libtorrent is needing to be built from source. Always check the libtorrent docs for any updates to build procedures.

Ubuntu

** These are the basic steps copied from the forum**

./configure --enable-python-binding
make
sudo checkinstall

This will install libtorrent and bindings in correct place. I have substituted make install for checkinstall because checkinstall creates a deb package that then can be used by dpkg to remove all the installed files easily.

Also if using a tarball from svn so you would need to create the configure script by runnning the autotool script:

./autotool.sh

I have not mentioned dependencies however both running autotool.sh and configure will warn if missing. If updating from an already included libtorrent you can get the dependencies using apt-get:

sudo apt-get build-dep libtorrent-rasterbar

Windows

The versions of OpenSSL, Boost & libtorrent are outdated but should be no issue using latest releases

1. Install the following:

• MS VC++ 2008/2010 Express: http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express
• OpenSSL win32 v1.0.0 (non-light): http://www.slproweb.com/products/Win32OpenSSL.html
• Python 2.7

2. Download lastest boost and libtorrent 0.15.10 tarball and extract to C:\ drive.

3. Build boost by opening command prompt and execute the following commands:

  bootstrap.bat
  b2

Building Boost takes a while and can take several gigabytes of space Close the prompt when done.

4. Edit the file 'C:\boost_1_49_0\tools\build\v2\user-config.jam' to force msvc version:

using msvc : 9.0 ;

5. Open Visual Studio command prompt a. Setup the environmental variables

set INCLUDE=C:\OpenSSL-Win32\include;%INCLUDE%
set LIB=C:\OpenSSL-Win32\lib;%LIB%
set BOOST_ROOT=C:\boost_1_49_0
set BOOST_BUILD_PATH=%BOOST_ROOT%
set PATH=%BOOST_ROOT%;%PATH%

b. Navigate to libtorrent python bindings folder

cd C:\libtorrent-rasterbar-0.15.10\bindings\python

c. Build libtorrent with python bindings:

C:\python27\python.exe setup.py  build

If there is no setup.py (i.e. downloaded from repository) on Windows you can simple use setup.py.in instead.

You can create setup.py on Ubuntu: (although makes no difference to the windows section of the script)

sudo apt-get install libtool libboost1.46-all-dev
./autotool.sh
./configure  --enable-python-binding

Non-python build instructions for reference: Leechcraft and QBittorrent

Install only debug tools

Build libtorrent with debug enabled (edit setup.py release to debug)

C:\libtorrent-rasterbar-0.16.6\bindings\python\bin\msvc-9.0\debug\boost-source\geoip-static\link-static\optimization-space\threading-multi

In windbg C:\Program Files\Debugging Tools for Windows (x86)\windbg.exe: File|Open Executable and tick Debug child processes

Hit F5 or Go a few times to get the program running

The following command after a crash:

`!analyze -v -f`
