Watch the output console for errors. + +\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 or add the following entry with type PATH `LIBUSB_INCLUDE_DIRS` to the directory for `libusb.h`, e.g. `C:\local\libusb-1.0.22\include\libusb-1.0`. +- Set or add the following entry with type FILEPATH `LIBUSB_LIBRARIES` to the full path for `libusb-1.0.lib`, e.g. `C:\local\libusb-1.0.22\MS64\dll\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, LibUSB v1.0.19 is required to use most USB3 controllers. + +\subsection build_in_msvc Build the project in MSVC +- Open the generated project file in MSVC, e.g. `C:\cygwin64\home\admin\uhd\host\build\UHD.sln`. +- 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. + +\subsection 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 compile_binary_installer_mscv Compiling a binary installer +- Building the "PACKAGE" project will produce a binary installer if NSIS is installed. This installer will be for either 64 bit or 32 bit as chosen during the CMake step. +- Select the "PACKAGE" project in the Solution Explorer, right-click, and choose "Build". + +\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 build_instructions_osx Build Instructions (Mac OS X) + +### X11/XQuartz or Terminal + +For the purposes of building and using UHD, you can use Apple's Terminal.app if you so choose, no matter how you install UHD. + +That said, running almost any graphical interface (GUI) will require downloading and installing X11/XQuartz first. Through OSX 10.8, Apple provided a means to install X11.app, but XQuartz has always been more up to date. Staring in 10.9, Apple no longer provides a full working version of X11.app. Hence, just use XQuartz from the get-go. Note that unless you experiment with using the Quartz interface to various graphical toolkits (e.g., GTK), you must use X11 as the terminal interface for any GUI applications. + +### Xcode + +Apple provides a fully integrated development environment via their Xcode toolkit, which can be downloaded either via the App store or directly from Apple's Developer area depending on the version of OSX in use. Xcode provides the compilers and related development tools needed to build or execute UHD and its dependencies. + +Once Xcode is installed, you must still install the Command Line Tools, which can be accomplished by running Xcode.app, then going to Preferences... -> Downloads and making sure Command Line Tools is selected/enabled [feel free to select other downloads too]. You might be able to install the Command Line Tools in a terminal using + + xcode-select --install + +but this command will not work with every OSX / Xcode combination (e.g., does not work with OSX 10.8 and Xcode 5, but does work with OSX 10.9 and Xcode 5). + +Once the Command Line Tools are installed, UHD and other projects can be installed either from source or, preferably, via MacPorts. + +### Background Dependencies + +There are a number of background libraries and applications that must be installed from source or binary in order to compile or execute UHD; for a full list, see \ref build_dependencies. These can be obtained by using <a href="http://www.macports.org/">MacPorts</a>, <a href="http://fink.sourceforge.net/">Fink</a>, <a href="http://brew.sh/">HomeBrew</a>, and/or from source / scratch. MacPorts tends to be more up-to-date with respect to new releases, which can be both a blessing and a curse since sometimes new released are untested and result in build or runtime errors. MacPorts, HomeBrew, and Fink offer thousands of ready-to-install libraries and applications, and hence they are highly recommended to use instead of installing from source / scratch. + +Many UHD developers first install UHD using MacPorts in order to get all of the necessary background dependencies installed, then remove just UHD via + + sudo port install uhd + sudo port uninstall uhd + +\b NOTE: We highly recommended that all dependencies be installed via the same package manager! When issues arise, they are much easier to track down, and updating to newer versions of UHD as well as dependencies is much easier. + +\b NOTE: Other package managers (e.g., Fink, HomeBrew) will require different commands than the above to install all dependencies and then remove the UHD install. Please consult the specific package manager in use for how to do these commands properly; they will not be covered here. + +#### Compiling UHD from Source + +Installing UHD from source follows the standard cmake method as found in many places, with a few arguments to make sure cmake always finds the correct version of Python, and uses the desired compiler. First, download the source code either via a release or via GIT. + +For example, on OSX 10.8+ and using Xcode's legacy Apple GCC (via llvm), MacPorts installed into /opt/local (the default), and for Python 2.7 as installed by MacPorts, issue the following commands from within the UHD source directory: + + $ mkdir build + $ cd build + $ CC=/usr/bin/llvm-gcc CXX=/usr/bin/llvm-g++ cmake -DCMAKE_INSTALL_PREFIX=/opt/local -DPYTHON_EXECUTABLE=/opt/local/bin/python2.7 -DPYTHON_INCLUDE_DIR=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Headers -DPYTHON_LIBRARY=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Python ../host + $ make + +If make succeeds, then you can test the build for errors via + + $ make test + +To install the build, issue + + $ sudo make install + +Selecting another compiler is as simple as changing the CC and CXX pre-arguments to the cmake command. Similarly, one can change the install prefix by changing the setting of the variable CMAKE_INSTALL_PREFIX. + +\b NOTE: All of the PYTHON defines must point to the same install of Python, otherwise runtime errors are likely to occur. + +\b NOTE: When using some other package manager (e.g., Fink, HomeBrew), the actual variable settings (-D...=...) will be different than those above. Please consult the specific package manager in use for how to do these settings properly; they will not be covered here. + +\section post_install_tasks Post-Install Tasks + +- After installing, you might want to download the FPGA images packages by running + `uhd_images_downloader` on the command line, or one of these executables (the actual path may differ based on your installation): + + Linux: /usr/local/lib/uhd/utils/uhd_images_downloader.py + + Windows: C:\\Program Files\\share\\uhd\\utils\\uhd_images_downloader.py + + Mac OS X: In MacPorts, when UHD is installed the images are automatically downloaded and installed into their proper location. For any other package manager or install method, you should execute the uhd_images_downloader.py script to get the images installed appropriately. + +- For USB-Based devices, make sure to read \ref transport_usb for platform-specific post-installation tasks. + +\section build_apps Building applications that require UHD using CMake + +If your application uses CMake as a build system, the following command +will setup up your build environment to link against UHD: + +\code{.cmake} +find_package(UHD "3.10.0") +\endcode + +This will set the CMake variable `UHD_INCLUDE_DIRS` and `UHD_LIBRARIES` +accordingly. + +See the example in `examples/init_usrp` for more details, as well as +the UHDConfig.cmake file that gets installed along with the UHD libraries. + +\section build_static Static Builds + +Using CMake, UHD can be built as a static library by switching on +`ENABLE_STATIC_LIBS`. + + cmake -DENABLE_STATIC_LIBS=ON <path to UHD source> + +When linking the static library, you must ensure that the library +is loaded in its entirety, otherwise global objects aren't initialized +at load-time and it will always fail to detect any devices. +Also, \b all UHD dependencies for UHD must be provided unless your +linker has other ways of resolving library dependencies. + +With the GNU ld linker (e.g. on Linux platforms), this is done using +the `--whole-archive` switch. Using the GNU C++ compiler, the correct +command line is: + + g++ your_uhd_app.cpp -Wl,-whole-archive <path to UHD libs>/libuhd.a -Wl,-no-whole-archive -ldl -lpthread -l<all other libraries> + +Note that `--whole-archive` is disabled after including `libuhd.a`. +The exact list of libraries depends on your UHD build. When using `UHDConfig.cmake` +(see \ref build_apps), the path to `libuhd.a` is saved into `UHD_LIBRARIES`, +and `UHD_STATIC_LIB_DEPS` lists the required dependencies. See `UHDConfig.cmake` +for details. + +*/ +// vim:ft=doxygen: |
