**[Second Life][] is a free 3D virtual world where users can create, connect and chat with others from around the
world.** This repository contains a fork of the source code for the official client.
## Open Source
Second Life provides a huge variety of tools for expression, content creation, socialization and play. Its vibrancy is
only possible because of input and contributions from its residents. The client codebase has been open source since
2007 and is available under the LGPL license. The [Open Source Portal][] contains additional information about Linden
Lab's open source history and projects.
## Download
Most people use a pre-built viewer release to access Second Life. Windows and macOS builds are
[published on the official website][download]. More experimental viewers, such as release candidates and
project viewers, are detailed on the [Alternate Viewers page](https://releasenotes.secondlife.com/viewer.html).
### Third Party Viewers
Third party maintained forks, which include Linux compatible builds, are indexed in the [Third Party Viewer Directory][tpv].
## Build Instructions
[Windows](https://wiki.secondlife.com/wiki/Build_the_Viewer_on_Windows)
### macOS
```
# port install git cmake pkgconfig apr-util boost collada-dom freealut hunspell jsoncpp libsdl2 openjpeg uriparser
$ export LL_BUILD="-DLL_DARWIN=1 -DPIC -fPIC -gdwarf-2 -stdlib=libc++ -iwithsysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -DLL_RELEASE=1 -DLL_RELEASE_FOR_DOWNLOAD=1 -std=c++17"
```
### Debian/Ubuntu
```
# apt install git cmake pkg-config libalut-dev libaprutil1-dev libboost-fiber-dev libboost-program-options-dev libboost-regex-dev libcollada-dom-dev libexpat1-dev libfltk1.3-dev libfontconfig-dev libfreetype-dev libglu1-mesa-dev libhunspell-dev libjpeg-dev libjsoncpp-dev libmeshoptimizer-dev libnghttp2-dev libpng-dev libpipewire-0.3-dev libsdl2-dev liburiparser-dev libvlc-dev libvlccore-dev libvorbis-dev libxft-dev libxmlrpc-epi-dev libxxhash-dev
# apt install libnanosvg-dev
$ export LL_BUILD="-DLL_LINUX=1 -fPIC"
```
libnanosvg-dev is not available yet on Debian 12.5.
libfontconfig-dev, libfreetype-dev, libjpegdev, libpng-dev, and libxft-dev may not be pulled in automatically by another package already on a minimal debootstrapped system.
### Fedora
```
# dnf install git gcc-c++ cmake zstd freealut-devel apr-util-devel boost-devel collada-dom-devel expat-devel fltk-devel hunspell-devel jsoncpp-devel libcurl-devel libnghttp2-devel libvorbis-devel mesa-libGLU-devel nanosvg-devel openjpeg2-devel openssl-devel pipewire-devel pulseaudio-libs-devel SDL2-devel uriparser-devel vlc-devel xmlrpc-epi-devel xxhash-devel
$ export LL_BUILD="-DLL_LINUX=1 -fPIC"
```
### FreeBSD
```
# portmaster devel/git devel/cmake-core devel/pkgconf audio/freealut devel/apr1 devel/collada-dom x11-toolkits/fltk textproc/hunspell misc/meshoptimizer graphics/nanosvg graphics/openjpeg devel/sdl20 net/uriparser multimedia/vlc audio/libvorbis net/xmlrpc-epi devel/xxhash
$ setenv LL_BUILD "-fPIC -std=c++17"
```
### Common
```
$ cd viewer
$ git remote add megapahit https://megapahit.org/viewer.git
$ git fetch megapahit
$ git checkout megapahit/main
$ mkdir -p build
$ cd build
$ cmake -DCMAKE_BUILD_TYPE:STRING=Release -DADDRESS_SIZE:INTERNAL=64 -DUSESYSTEMLIBS:BOOL=ON -DUSE_OPENAL:BOOL=ON -DLL_TESTS:BOOL=OFF -DNDOF:BOOL=OFF -DVIEWER_CHANNEL:STRING=Megapahit -DVIEWER_BINARY_NAME:STRING=megapahit -DBUILD_SHARED_LIBS:BOOL=OFF -DPACKAGE:BOOL=OFF -DINSTALL:BOOL=ON ../indra
$ make -j12
$ sudo make install
$ megapahit
```
## Example
