\section build_dependencies Build Dependencies

<b>Linux Notes:</b>
This is dependent on the distribution you are using, but most, if not all, of
the dependencies should be available in the package repositories for your
package manager.

<b>Mac OS X Notes:</b>
Install the Xcode app to get the build tools (GCC and Make).
Use MacPorts to get the Boost and Cheetah dependencies.
Other dependencies can be downloaded as DMG installers from the web
or installed via MacPorts.
See the UHD OS X page for more information: http://code.ettus.com/redmine/ettus/projects/uhd/wiki/UHD_OS_X 

<b>Windows Notes:</b>
The dependencies can be acquired through installable EXE files.
Usually, the Windows installer can be found on the project's website.
Some projects do not host Windows installers, and if this is the case,
follow the auxiliary download URL for the Windows installer (below).

\section git Git
Required to check out the repository.
On Windows, install Cygwin with Git support to checkout the repository
or install msysGit from http://code.google.com/p/msysgit/downloads/list.

\section build_instructions_unix Build Instructions (Unix)

\subsection generate_unix Generate Makefiles with CMake

    cd <uhd-repo-path>/host
    mkdir build
    cd build
    cmake ../

Additionally, configuration variables can be passed into CMake via the command line.
The following common-use configuration variables are listed below:

- For a custom install prefix: `-DCMAKE_INSTALL_PREFIX=<install-path>`
- To install libs into lib64: `cmake -DLIB_SUFFIX=64`

Example usage:

    cmake -DCMAKE_INSTALL_PREFIX=/opt/uhd ../

\subsection build_install_unix Build and install

    make
    make test
    sudo make install

\subsection libpath_linux Setup the library path (Linux)

Make sure that `libuhd.so` is in your `LD_LIBRARY_PATH`,
or add it to `/etc/ld.so.conf` and make sure to run:

    sudo ldconfig

\section build_instructions_windows Build Instructions (Windows)

\subsection cmake_win Generate the project with CMake

- Open the CMake GUI.
- Set the path to the source code: `<uhd-repo-path>/host`.
- Set the path to the build directory: `<uhd-repo-path>/host/build`.
- Make sure that the paths do not contain spaces.
- Click "Configure" and select "Microsoft Visual Studio 10".
- Set the build variables and click "Configure" again.
- Click "Generate", and a project file will be created in the build directory.

\subsection libusb_notes LibUSB notes

On Windows, CMake does not have the advantage of `pkg-config`,
so we must manually tell CMake how to locate the LibUSB header and lib.

- From the CMake GUI, select "Advanced View".
- Set `LIBUSB_INCLUDE_DIRS` to the directory with `libusb.h`.
- Set `LIBUSB_LIBRARIES` to the full path for `libusb-1.0.lib`.
- Recommend the static `libusb-1.0.lib` to simplify runtime dependencies.
- Check the box to enable USB support, click "Configure" and "Generate".

<b>Note:</b> On Windows, LibUSBx is required to use most USB3 controllers.

\subsection build_in_msvc Build the project in MSVC
- Open the generated project file in MSVC.
- Change the build type from "Debug" to "Release".
- Select the "Build All" target, right-click, and choose "Build".
- Select the install target, right-click, and choose "Build".

<b>Note:</b>
You may not have permission to build the install target.
You need to be an administrator or to run MSVC as administrator.

\section build_msvc_cmd_line Build the project in MSVC (command line)
Open the Visual Studio Command Prompt Shorcut:

    cd <uhd-repo-path>\host\build
    DevEnv uhd.sln /build Release /project ALL_BUILD
    DevEnv uhd.sln /build Release /project INSTALL

\subsection path_env Setup the PATH environment variable
* Add the UHD bin path to `%PATH%` (usually `C:\\Program Files\\UHD\\bin`)

<b>Note:</b>
The default interface for editing environment variable paths in Windows is very poor.
We recommend using "Rapid Environment Editor" (http://www.rapidee.com) over the default editor.

\section post_install_tasks Post-Install Tasks

For USB-based devices,
see the `USB Transport Application Notes <./transport.html#usb-transport-libusb>`_
for platform-specific post-installation tasks.

\section post_install_tasks_macosx Post-Install Tasks (Mac OS X)

Make sure that the value of `CMAKE_INSTALL_PREFIX` is at or near the 
front of the shell `PATH` environment variable.  Do \b NOT set 
`DYLD_LIBRARY_PATH` or any related DYLD environment variable 
permanently; these work differently than under Linux and should be 
used for testing / temporary purposes only.
