I have cloned libuvc_ros to my catkin_ws/src and do rosmake libuvc_camera, and I got this error:
ERROR: cannot launch node of type [libuvc_camera/camera_node]: can't locate node [camera_node] in package [libuvc_camera]
I did install ros-kinetic-uvc-camera and ros-kinetic-libuvc-camera, and I'm quite lost. Can someone please tell me what is the correct step?
If You Don't Want To Modify libuvc_camera It's Better To Use Binaries (ros-kinetic-uvc-camera and ros-kinetic-libuvc-camera)
But If You Want To Compile It Anyway, First Remove ros-kinetic-uvc-camera and ros-kinetic-libuvc-camera and then Be Sure To Set ROS Path To catkin_ws/src By Running source <path_to_catkin>/catkin_ws/devel/setup.bash (or Place It In ~/.bashrc for all terminals) and then in catkin_ws Run catkin_make <-j if u want multiple job>
I solved it with ros packageuvc-camera and referred answers from setting a usb camera and stream usb camera in ros.
I checked the ros packages installed with rospack list-names and found uvc-camera is appropriate enough, then I started camera node using rosrun uvc_camera uvc_camera_node _device:=/dev/video1, in rostopic list I saw /camera_info and /image_raw which proved my solution.

I got this problem when I use git svn to checkout my svn repos.Then I follow some suggestions from website and try to reinstall svn:core by
sudo cpan SVN:Core
but I still got following error when I try to check out a svn repos.

error: git-svn died of signal 6
I check from website that the function is declared in the library header:
libsvn_swig_perl/swigutil_pl.h
But I didn't find error message related this lib (I did see some warning) when I install SVN:Core.
Are there something I need to setup or check for this issue when I install SVN:Core to make my git svn check out work properly?
Thank you~~

You should not need to manually install Perl package SVN::Core. The Homebrew formula subversion already does that — but, only for Intel hardware currently, as you can see. Volunteering to contribute other hardware support would be warmly welcome.
That formula (script) is what powers brew install subversion. Does this command work for you at all? Can you run svn info? If not, then you should first of all get svn installation working — and only then add git-svn on top. This is because the dependency structure looks like this:
If the bottom-most box is broken for you, then messing with Perl packages is guaranteed to not help.

Please be specific; which website? I don't see any _svn_ra_make_callbacks in the latest upstream source, neither in 1.14.1 tarball.
I keep receiving this error when running my App.js for React Native that was working perfectly well before I attempted installing Victory charts. Somehow something broke and after over three hours of work I am unable to figure out a solution. I have tried everything I could find on the web including uninstalling watchman, reinstalling watchman, reverting to React Native 0.55.4, some other recommended commands. Nothing is working.I am so confused.
$ yarn add react-native-scripts
This helped.
I think the other library may hurt the installation part of your package. To solve this issue on IOS you need to add its library like below:
First do 'yarn add react-native-scripts'. In the case that it dose't work continue other steps.
1-Go to the node module of your project and find the package folder and find the ios file inside it.
2- Then drag it into ‘library’ section of your xcode. (It is the subset of your project folders)
3- Then go to ‘build phase’ and in the ‘Link binary with libraries’ add it there by clicking on the plus sign
4- Then in some cases you need to add the correct path of the ios file inside your node module in the xcode. To do that you should go to ‘build setting’ section in the xcode and search header there. Then you need to add the path there below other paths.
5- Then clear everything (cmd+shift+k) and then finally compile it.
I hope it works for you.
In my case the "crna-entry.js" file does exist in the roots and my project should work (nothing have been modified from last time when it does work).
After hours searching, finally I figured out the reason:
the packager's directory checking is case-sensitive and in windows terminal the drive "c:/" will not be auto-corrected to "C:/" which will lead to error.
Hope this will help someone who gets the same error.
Below is the full error message:
The development server returned response error code:404 Cannot find
entry file node_modules/react-native-scripts/build/bin/crna-entry.js

I'm trying to use ogr2ogr to filter a shapefile. I'm working through Mike Bostock's Let's Make a Map tutorial. A bit of googling - including here - hasn't led to any solutions yet. I'm also VERY new to topojson (and shapefiles in general; my background is in economics/statistical software like Stata), so I'm not sure what I'm doing and where things are going wrong. Either way - here's the error result I'm getting:
dyld: Library not loaded: /usr/local/lib/liblwgeom-2.1.1.dylib
Referenced from: /usr/local/Cellar/libspatialite/4.1.1/lib/libspatialite.5.dylib
Reason: image not found
Trace/BPT trap: 5
No idea what liblwgeom-2.1.1.dylib is, what it does, where I get it, etc. Google hasn't helped much on defining it either.
FWIW, I'm on a Mac, I brew installed npm and gdal, and then npm installed topojson.
Thanks,
a
Edited to add: I just brew reinstalled gdal, because I remembered getting a warning (Caveats). See below:
==> Caveats
For non-homebrew python (2.x), you need to amend your PYTHONPATH like so:
export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH
This version of GDAL was built with Python support. In addition to providing
modules that makes GDAL functions available to Python scripts, the Python
binding provides additional command line tools.
I actually tried to run export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH literally as-is, and it returned nothing. (Not sure if something happened in the background?) Basically fumbling in the dark!
I'm trying out casperJS to run some automated tests. On windows. I followed this installation guide but am stuck.
when I try to run a simple test from the command line like this:
casperjs.bat smoketest.js
I get the following error:
Error: Cannot find module 'C:/code/base/main/Shared/casperjs\modules\cli.js'
I checked, and the file cli.js does exist under the specified path.
I thought the problem could be the mixture of forward and backward slashes in the path, but I edited the bootstrap.js casper code to hard code the path and it made no difference - it still the cannot find module.
I'm have tried this using phantomJS version 1.9.0, and 1.8.2.
Anyone know what I am doing wrong?
Has anyone had success running casper on Windows?
This is due to a bug in PhantomJS 1.9.0 that does not allow for absolute path loading in Windows. Afaik, this should only be apparent if you are using a master build of CasperJS (v1.1).
This bug has been fixed, but is not yet in the Windows binary. You can compile it yourself if you'd like, but that can take quite a bit of time.
I was using the master build of casper. With the latest released version, 1.0.2, it works fine.
I am not getting TBB to work. I am following the steps in the "Getting started" document.
I am doing the following steps:
downloading the linux files + the sources files.
extracting them in 1 directory
calling make
going to tbb.../bin calling source tbbvars.sh intel64
going to examples/Getting_started/sub_string_finder
calling make
I then get the error:
sub_string_finder.cpp:32:30: fatal error: tbb/parallel_for.h: No such file or directory
I really googled a lot but can't find any related stuff.
I did also try to add some -I statement but it didnt help
I assume it is kind of a including/linking problem but I dont know how to fix.
This is all done on fedora 16 64bit. (kernel 3.1.4) // TBB version 4.0
The solution was to install tbb-devel package.
