on Sep 8th 2016 I did: Ran brew update and retried Ran brew doctor, no real issues there Bug reports: I installed PCL from brew with qt support: brew install homebrew/science/pcl --with-qt, this installed jpeg among other things. Trying to run pcl_vlp_viewer results in this error: dyld: Symbol not found: __cg_jpeg_resync_to_restart Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
Expected in: /usr/local/lib/libjpeg.8.dylib in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO Trace/BPT trap: 5 Seems that something is trying to load Framework JPEG library but it is actually built with brew jpeg. Not sure what would be the appropriate fix. PS: the program I am trying to build shows exactly same error Homebrew member jonchang commented Sep 20, 2016 Hi @nizar-sallem, could you please check the Issue Template and link the output of brew gist-logs pcl and the output of brew config? This will help us diagnose the issue. Thanks! dpo added the needs response label Oct 14, 2016 Sign up for free to join this conversation on GitHub. Already have an account?

will use Cmake rather than Qmake.The program we are going to write is a simple PCL visualizer which allow to change a randomly generated point cloud color. The tutorial was tested pcl source on Linux Ubuntu 12.04 and 14.04. It also seems to be working fine
on Windows 8.1 x64. Feel free to push modifications into the git repo to make this code/tutorial compatible with your platform pcl tutorials ! Contents Create a PCL visualizer in Qt with cmake The project Qt configuration User interface (UI) The code main.cpp pclviewer.h pclviewer.cpp Compiling and running More on Qt and PCL The project For this https://github.com/Homebrew/homebrew-science/issues/4241 project Qt is of course mandatory, make sure it is installed and PCL deals with it. qmake is a tool that helps simplify the build process for development project across different platforms, we will use cmake instead because most projects in PCL uses cmake and it is simpler in my opinion. This is how I organized the project: the build folder contains all built files and the src folder http://pointclouds.org/documentation/tutorials/qt_visualizer.php holds all sources files . ├── build └── src ├── CMakeLists.txt ├── main.cpp ├── pclviewer.cpp ├── pclviewer.h ├── pclviewer.ui └── pcl_visualizer.pro If you want to change this layout you will have to do minor modifications in the code, especially line 2 of pclviewer.cpp Create the folder tree and download the sources files from github. Note File paths should not contain any special caracter or the compilation might fail with a moc: Cannot open options file specified with @ error message. Qt configuration First we will take a look at how Qt is configured to build this project. Simply open pcl_visualizer.pro with Qt (or double click on the file) and go to the Projects tab In this example note that I deleted the Debug configuration and only kept the Release config. Use relative paths like this is better than absolute paths; this project should work wherever it has been put. We specify in the general section that we want to build in the folder ../build (this is a relative path from the .pro file). The first step of the building is to call cmake (from the build folder) with argument ../src<

However, I don't know how to use the library in my project, Can anyone elaborate in this? I'm trying to run the code in https://github.com/roomplan/tango-examples-java.git, the Point Cloud with PCL one, and I have tried to write an Android.mk file, but I have field. Noting That, I'm using Android Studio with NDK, and Windows 8 as running operating System. EDIT: I had fix my issue with PCL Linking to My Project, The library had recognized and the project build successfully. However, When I run the application on Tango device I got an UnsatisfiedLinkexception as follow: ? E/art: dlopen("/data/app-lib/com.projecttango.experiments.javapointcloud-2/libhelloPcl.so", RTLD_LAZY) failed: dlopen failed: could not load library "libflann.so" needed by "libhelloPcl.so"; caused by library "libflann.so" not found ?
