This tutorial explains how to build the Point Cloud Libraryfrom MacPorts and source on Mac OS X platforms, and tries to guide youthrough the download and building of all the required dependencies.
Before getting started download and install the following prerequisites forMac OS X:
- Explore the world of Mac. Check out MacBook Pro, MacBook Air, iMac, Mac mini, and more. Visit the Apple site to learn, buy, and get support.
- Mac OS X Snow Leopard is intended to be a release aimed to refine the existing feature set, expand the technological capabilities of the operating system, and improve application efficiency. Many of the changes involve how the system works in the background and are not intended to be seen by the user.
- XCode (https://developer.apple.com/xcode/)
- Apple's powerful integrated development environment
- MacPorts (http://www.macports.org)
- An open-source community initiative to design an easy-to-usesystem for compiling, installing, and upgrading either command-line, X11 orAqua based open-source software on the Mac OS X operating system.
The most important point when choosing the best OS is the ability to get security updates. While Apple generally does not announce the OS end of life dates, it is possible to know when they stop releasing security updates from this page. How to get the PID of a process by giving the process name in Mac OS X? Ask Question Asked 8 years, 9 months ago. Active 7 months ago. Viewed 115k times 52. I am writing a script to monitor the CPU and MEM of any given process. For that i need to send in the name of the process to be monitored as a commandline argument.
In order to compile every component of the PCL library we need to download andcompile a series of 3rd party library dependencies. We'll cover the building,compiling and installing of everything in the following sections:
Required
The following libraries are Required to build PCL.
- CMake version >= 3.5.0 (http://www.cmake.org)
Cross-platform, open-source build system.
Note
Walking simulator (zeindiegames) mac os. Though not a dependency per se, the PCL community relies heavily on CMakefor the libraries build process.
- Boost version >= 1.46.1 (http://www.boost.org/)
Provides free peer-reviewed portable C++ source libraries. Used for sharedpointers, and threading.
- Eigen version >= 3.0.0 (http://eigen.tuxfamily.org/)
Unified matrix library. Used as the matrix backend for SSE optimized math.
FLANN version >= 1.6.8(http://www.cs.ubc.ca/research/flann/)Library for performing fast approximate nearest neighbor searches in highdimensional spaces. Used in kdtree for fast approximate nearest neighborssearch.
- Visualization ToolKit (VTK) version >= 5.6.1 (http://www.vtk.org/)
Software system for 3D computer graphics, image processing and visualization.Used in visualization for 3D point cloud rendering and visualization.
Optional
The following libraries are Optional and provide extended functionalitywithin PCL, ie Kinect support.
- Qhull version >= 2011.1 (http://www.qhull.org/)
- computes the convex hull, Delaunay triangulation, Voronoi diagram, halfspaceintersection about a point, furthest-site Delaunay triangulation, andfurthest-site Voronoi diagram. Used for convex/concave hull decompositionsin surface.
- libusb (http://www.libusb.org/)
- A library that gives user level applications uniform access to USB devicesacross many different operating systems.
- PCL Patched OpenNI/Sensor (http://www.openni.org/)
- The OpenNI Framework provides the interface for physical devices and formiddleware components. Used to grab point clouds from OpenNI compliantdevices.
Advanced (Developers)
The following libraries are Advanced and provide additional functionalityfor PCL developers:
- googletest version >= 1.6.0 (http://code.google.com/p/googletest/)
- Google's framework for writing C++ tests on a variety of platforms. Usedto build test units.
- Doxygen (http://www.doxygen.org)
- A documentation system for C++, C, Java, Objective-C, Python, IDL (Corba andMicrosoft flavors), Fortran, VHDL, PHP, C#, and to some extent D.
- Sphinx (http://sphinx-doc.org/)
- A tool that makes it easy to create intelligent and beautifuldocumentation.
By now you should have downloaded and installed the latest versions of XCode andMacPorts under the Prerequisites section. We'll be installing mostdependencies available via MacPorts and the rest will be built from source.
Install CMake
Install Boost
Install Eigen
Install FLANN
Install VTK
To install via MacPorts:
To install from source download the source fromhttp://www.vtk.org/VTK/resources/software.html
Follow the README.html for compiling on UNIX / Cygwin / Mac OSX:
Press [c] for initial configuration
Press [t] to get into advanced mode and change the following:
Note
VTK must be built with Cocoa support and must be installed,in order for the visualization module to be able to compile. If you donot require visualisation, you may omit this step.
Press [g] to generate the make files.
Press [q] to quit.
Then run:
Install Qhull
Install libusb
Install Patched OpenNI and Sensor
Download the patched versions of OpenNI and Sensor from the PCL downloads pagehttp://pointclouds.org/downloads/macosx.html
Extract, build, fix permissions and install OpenNI:
In addition the following primesense xml config found within the patched OpenNIdownload needs its permissions fixed and copied to the correct location to forthe Kinect to work on Mac OS X:
Extract, build, fix permissions and install Sensor:
At this point you should have everything needed installed to build PCL withalmost no additional configuration.
Checkout the PCL source from the Github:
Create the build directories, configure CMake, build and install:
The customization of the build process is out of the scope of this tutorial andis covered in greater detail in the Customizing the PCL build process tutorial.
We finally managed to compile the Point Cloud Library (PCL) for Mac OS X. Youcan start using them in your project by following the Using PCL in your own project tutorial.
API Documentation (Doxygen)
Install Doxygen via MacPorts:
![Get To The Point Mac OS Get To The Point Mac OS](https://support.apple.com/library/content/dam/edam/applecare/images/en_US/macos/Catalina/macos-catalina-system-prefs-trackpad-mbp.png)
Or install the Prebuilt binary for Mac OS X(http://www.stack.nl/~dimitri/doxygen/download.html#latestsrc)
After installed you can build the documentation:
Tutorials (Sphinx)
In addition to the API documentation there is also tutorial documentation builtusing Sphinx. The easiest way to get this installed is using pythonseasy_install:
The Sphinx documentation also requires the third party contrib extensionsphinxcontrib-doxylink (https://pypi.python.org/pypi/sphinxcontrib-doxylink)to reference the Doxygen built documentation.
To install from source you'll also need Mercurial:
Get To The Point Mac Os X
After installed you can build the tutorials:
Note
Sphinx can be installed via MacPorts but is a bit of a pain getting all thePYTHON_PATH's in order
It sounds like the download may not have failed but the installation did so the only thing left that your MBP can boot from is the Recovery partition (see this discussion). Since you don't want to loose all your documents and you don't have a backup to restore from, I can think of a few things to try.
Reboot and hold down the option key to see what the MBP sees as bootable. If it's just the Recovery partition, that's where you are.
If there's a second choice (e.g., Macintosh HD), and it doesn't boot from that, try to reboot and hold down the shift key to start in Safe Mode.
Getting more extreme would be to get an external drive and Reinstall OS X on it so that you can boot from it and copy over your documents from the internal drive using Setup Assistant.
Get To The Point Mac Os 11
FInally, you could reinstall OS X on the internal. Coin: totem mac os. That should get Mountain Lion working again without damaging the rest of your files.
Get Mac Os Catalina
