Build Dependencies

Linux Notes: The dependencies can be acquired through the package manager.

Mac OS X Notes: Install the "Xcode Developer Tools" 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.

Windows Notes: 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).

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

C++ compiler

Build Instructions (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=<prefix>
To install libs into lib64: cmake -DLIB_SUFFIX=64

Example usage:

cmake -DCMAKE_INSTALL_PREFIX=/opt/uhd ../

Build and install

make
make test
sudo make install

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

Setup the library path (Mac OS X)

Make sure that libuhd.dylib is in your DYLD_LIBRARY_PATH

Build Instructions (Windows)

Generate the project with cmake

Open the cmake gui program.
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 the MSVC compiler.
Set the build variables and click configure again.
Click generate and a project file will be created in the build directory.

LibUSB cmake 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 "Advanded View":

Set LIBUSB_INCLUDE_DIR to the directory with "libusb.h".
Set LIBUSB_LIBRARIES to the full path for "libusb-1.0.lib".

Then check the boxes to enable USRP1 support, click configure and generate.

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.

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

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

Setup the PATH environment variable

Add the boost library path to %PATH% (usually c:\program files\boost\<version>\lib)
Add the uhd library path to %PATH% (usually c:\program files\uhd\lib)
Add the libusb library to %PATH% (if using usb support)

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