![]() Gr-audio: Audio Subsystems (system/OS dependent) Gr-qtgui: The QT-based Graphical User Interface Other compilers may work, but are not supported.Ĭppzmq is included (undocumentedly) in the debian and Ubuntu libzmq3-dev packages. Most recent systems have these packages available.Ī C/C++ compiler is also required. If, for example, you do not use any UHD-based hardware, do not worry about building gr-uhd.īefore trying to build these from source, please try your system's installation tool (apt-get, pkg_install, YaST, yum, urpmi, etc.) first. The list of required components is determined by what the user requires from GNU Radio. Not all dependencies are required for all components, and not all components are required for a given installation. GNU Radio tries to keep an up-to-date build guide for the majority of the supported operating systems on ( ). Instead, rely on your operating system's package manager or binary installation process (the apt-get or apt system in Debian and Ubuntu, yum or dnf in RedHat and Fedora, etc.). Most of these components do not need to be individually compiled or installed. If you are a ROS beginner and want to learn ROS basics fast, we recommend you take any of the following courses on Robot Ignite Academy:ĭid you like this video? Whatever the case, please leave a comment in the comments section below, so we can interact and learn from each other.The list of GNU Radio dependencies and the minimum required versions, if any, to build the various GNU Radio components. Prefer “sights and sounds” to “black and white”? We have a video covering this same post, just for you! The configuration directives in CMakeLists.txt must follow a particular order this is why commenting out the ‘project’ directive didn’t work, as the error message also hinted. The order in the configuration DOES count. Your CMakeLists.txt file MUST follow this format otherwise your packages will not build correctly. But what about commenting out parts of the file? Also according to ROS Wiki: Well, now you can see why renaming the file isn’t a good idea. Any CMake-compliant package contains one or more CMakeLists.txt file that describe how to build the code and where to install it to. The file CMakeLists.txt is the input to the CMake build system for building software packages. Step 3: Master the concept – what is CMakeLists.txt? Let’s talk more about that in the next section. Moral lesson: CMakeLists.txt can make or mar a project, if not properly modified. # Running command: "make -j2 -l2" in "/home/user/catkin_ws/build" Build files have been written to: /home/user/catkin_ws/build # add_compile_options(-std=c++11) user:~/catkin_ws$ catkin_make Project(cmakelists_test) -> uncomment this line We aren’t getting away with tampering with CMakeLists.txt, are we? Now, let’s repent and restore the file: remove the comment from the ‘project’ directive, save and run catkin_make again.
