   rapidjson libupnp libxslt libxss sqlcipher botan2 bzip2 json-c
```

### Checkout the source code
```bash
   cd ~ 
   git clone https://github.com/RetroShare/RetroShare.git retroshare
```

### Checkout the submodules
```bash
   cd retroshare
   git submodule update --init --remote libbitdht/ libretroshare/ openpgpsdk/ retroshare-webui/ 
   git submodule update --init --remote supportlibs/librnp supportlibs/restbed supportlibs/rapidjson
```

### Compile
```bash
   qmake CONFIG+=release CONFIG+=rs_jsonapi CONFIG+=rs_webui
   make
```

### Install
```bash
   sudo make install
```

The executable produced will be:  
```bash
 - /usr/bin/RetroShare  
```

### For packagers

Packagers can use PREFIX and LIB\_DIR to customize the installation paths:
```bash
   qmake PREFIX=/usr LIB_DIR=/usr/lib64 "CONFIG-=debug" "CONFIG+=release"
   make
   make INSTALL_ROOT=${PKGDIR} install
```
 
 
### libsqlcipher
If libsqlcipher is not available as a package

You need to place sqlcipher so that the hierarchy is:

      retroshare
          |
          +--- trunk
          |
          +--- lib
                |
                +---- sqlcipher
```bash
	mkdir lib
	cd lib
	git clone git://github.com/sqlcipher/sqlcipher.git
	cd sqlcipher
	./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypto"
	make
	cd ..
``` 

### Build options

* Mandatory
  * release or debug:			normally you would like to use the release option
* Extra features (optional)
  * rs_autologin:				enable autologin
  * retroshare_plugins:			build plugins
  * rs_webui:					enable remoting features
  * rs_jsonapi:					enable json api interface
  * gxsthewire					enable Wire service
  * wikipoos 					enable Wiki service
  * rs_use_native_dialogs		enable native dialogs
  * rs_deep_channels_index		build with deep channel indexing support
  * rs_deep_files_index			build with deep file indexing support
  * "CONFIG+=..."				enable other extra compile time features, you can find the almost complete list in file *<sourcefolder>\retroshare.pri*

Example:

```batch
qmake CONFIG-=debug CONFIG+=release CONFIG+=rs_use_native_dialog CONFIG+=rs_gui_cmark
qmake CONFIG+=rs_jsonapi CONFIG+=rs_webui CONFIG+=rs_autologin
qmake CONFIG+=rs_deep_channels_index CONFIG += gxsthewire CONFIG += wikipoos
```
