RakNet 4.081

Copyright (c) 2014, Oculus VR, Inc.

Package notes

The Help directory contains index.html, which is full help documentation in HTML format The Source directory contain all files required for the core of Raknet and is used if you want to use the source in your program or create your own dll The Samples directory contains code samples and one game using an older version of Raknet. The code samples each demonstrate one feature of Raknet. The game samples cover several features. The lib directory contains libs for debug and release versions of RakNet and RakVoice There is a make file for linux users in the root directory. Windows users can use projects under Samples\Project Samples

C# support

See Help\swigtutorial.html

Upgrading from version 3

See 3.x_to_4.x_upgrade.txt

Windows users (Visual Studio 2008 and 2010)

Load RakNet_VS2008.sln and convert if necessary.

After the project conversion, if you encounter error MSB4006, follow the steps below to fix it:

  1. Open project properties
  2. Click on "Common Properties"
  3. Click on "Framework and References"
  4. Look under "Build Properties"
  5. Change the "Copy Local" flag from "True" to "False"

For other compiler issues, please see Help/compilersetup.html

Windows users (VC6)

Not supported, but you can get by if you directly include the source.

CYGWIN users

Copy Include, Source, and whatever you want to run in the home directory. Then type g++ ../../lib/w32api/libws2_32.a *.cpp You can run a.exe. You might have to copy *.dll from cygwin\bin as well.

Linux users

Use cmake, or g++ -lpthread -g *.cpp in the /Source directory. With libcat, use g++ -pthread -g -I./../DependentExtensions *.cpp in the /Source directory.

64 bit use -m64 command line Sometimes you need -pthread instead of -lpthread

Command to build 64 bit chat example server from the /Source directory:

g++ -m64 -g -lpthread -I./ "../Samples/Chat Example/Chat Example Server.cpp" *.cpp

Command to build NATCompleteServer from the Samples/NATCompleteServer directory:

g++ -g -lpthread -I./ -I./../../Source main.cpp -I./../CloudServer ./../../Source/*.cpp ./../CloudServer/CloudServerHelper.cpp

Command to build autopatcher server from /Source directory:

g++ -lpthread -lpq -lssl -lbz2 -lssl -lcrypto -L/opt/PostgreSQL/9.0/lib -L../DependentExtensions/bzip2-1.0.6 -I/opt/PostgreSQL/9.0/include -I../DependentExtensions/bzip2-1.0.6 -I./ -I../DependentExtensions/Autopatcher -I../DependentExtensions/Autopatcher/AutopatcherPostgreRepository -I../DependentExtensions/PostgreSQLInterface -g *.cpp ../DependentExtensions/Autopatcher/AutopatcherServer.cpp ../DependentExtensions/Autopatcher/CreatePatch.cpp ../DependentExtensions/Autopatcher/MemoryCompressor.cpp ../DependentExtensions/Autopatcher/AutopatcherPostgreRepository/AutopatcherPostgreRepository.cpp ../DependentExtensions/PostgreSQLInterface/PostgreSQLInterface.cpp ../Samples/AutopatcherServer/AutopatcherServerTest.cpp

Command to build NATCompleteServer from /Source directory:

g++ -lpthread -I./ -I../Samples/CloudServer ../Samples/CloudServer/CloudServerHelper.cpp ../Samples/NATCompleteServer/main.cpp *.cpp

Command to build BigPacketTest from /Source directory:

g++ -lpthread -I./ ../Samples/BigPacketTest/BigPacketTest.cpp *.cpp

Or with debugging info on:

g++ -g -lpthread -I./ ../Samples/BigPacketTest/BigPacketTest.cpp *.cpp

If you get /usr/local/lib/libraknet.so: undefined reference to `__sync_fetch_and_add_4 then build with -march=i686

gdb ./a.out

Set breakpoint:

b file:line

Disable a breakpoint:

disable <breakpointNumber>

Delete a breakpoint:

delete <breakpointNumber>

Get a list of breakpoints:

info breakpoints

St breakpoint to be ignored that number of times

ignore <breakpointNumber> <count>
run

Other useful commands:

info stack
info locals
delete (Clears all breakpoints)
step (step into)
next (step over)
finish (step out)
continue to keep going after step or next
p <variableName>
For example: p users.orderedList.listArray[0].guid

Command to install g++

sudo apt-get install gcc-c++
sudo apt-get install build-essential

Or:

yum install gcc-c++

Or:

sudo apt-get update
sudo apt-get install g++

Command to install gdb

sudo apt-get install gdb

Command to install wget, used to download files from webpages sudo apt-get install wget

Series of commands for a new server: sudo apt-get install wget sudo apt-get update sudo apt-get install --fix-missing g++ sudo apt-get install gdb cd RakNet_Install_Directory\Source g++ -m64 -g -pthread -I./ "../Samples/Chat Example/Chat Example Server.cpp" *.cpp ./a.out

Mac Users

Open a Terminal window and type:

cd ~/Desktop/RakNet/Source
g++ -c -DNDEBUG -I -isysroot /Developer/SDKs/MacOSX10.5u.sdk/ -arch i386 *.cpp

Use whichever SDK you have. However, the 10.4 SDK is bugged and will not compile unless you use GCC 4.0 from inside XCODE

The sources should build cleanly. This gives you a bunch of PowerPC binaries, compiled against the 10.3.9 SDK which is a good thing.

Give the following command:

libtool -static -o raknetppc.a *.o

This will stitch together a static library for the PowerPC architecture. There may be warnings that some .o files do not have any symbols. If you want to be prudent, remove the named files (the .o files, not the .cpp files!) and re-run the libtool command.

Now, we build the source files for Intel:

gcc -c -I ../Include -isysroot /Developer/SDKs/MacOSX10.4u.sdk/ -arch i386 *.cpp

..and stitch it into a i386 library:

libtool -static -o rakneti386.a *.o

Now, type:

ls *.a

which should list the two .a files. Now, we make them into a universal binary:

lipo -create *.a -o libraknet.a

You now have a file named libraknet.a. This is the RakNet library, built to run on both PowerPC and Intel Macs. Enjoy! ;-)

IPod

Depending on what version you target, you may have to change two defines to not use 64 bit integers and floats or doubles.

Android

You will need the latest CYWGIN and the android SDK to build native code on the android. Under CYWGIN, you will need to run ndk-build on a directory for RakNet.

  1. Under cygwin, create the RakNet directory somewhere, such as under samples. For example, if you create the path \cygwin\home\Kevin\android-ndk-r4b\samples\RakNet

  2. I copied the Android.Manifest.xml and other files from another sample

  3. Under jni, you will need the following Android.mk

    LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := RakNet MY_PREFIX := $(LOCAL_PATH)/RakNetSources/ MY_SOURCES := $(wildcard $(MY_PREFIX)*.cpp) LOCAL_SRC_FILES += $(MY_SOURCES:$(MY_PREFIX)%=RakNetSources/%) include $(BUILD_SHARED_LIBRARY)

This version of Android.mk assumes there is a directory called RakNetSources, for example cygwin/home/Kevin/android-ndk-r4b/samples/RakNet/jni/RakNetSources

Under RakNetSources should be the /Source directory to RakNet. Rather than copy the files I used junction.exe http://technet.microsoft.com/en-us/sysinternals/bb896768.aspx

The command I used to create the junction was:

D:/cygwin/home/Kevin/android-ndk-r4b/samples/RakNet/jni/junction.exe -s D:/cygwin/home/Kevin/android-ndk-r4b/samples/RakNet/jni/RakNetSources D:/RakNet4/Source

To unjunction I used:

D:/cygwin/home/Kevin/android-ndk-r4b/samples/RakNet/jni/junction.exe -d D:/cygwin/home/Kevin/android-ndk-r4b/samples/RakNet/jni/RakNetSources

From within the CYWGIN enviroment, navigate to home/Kevin/android-ndk-r4b/samples/RakNet. Then type

../../ndk-build

Everything should build and you should end up with a .so file.

You should then be able to create a project in eclipse, and import cygwin/home/Kevin/android-ndk-r4b/samples/RakNet
