libuvc_camera install fails, OS X 10.11.12, ROS Indigo

[gunshi]

Hi, I cloned the most recent version of the libuvc_ros repo (master) into my src folder and ran catkin_make_isolated --pkg libuvc_camera --install , and then I got an error while building, I reproduced the error, as suggested, and got:

<== Failed to process package 'libuvc_camera': Command '['/Users/gunshigupta/ros_catkin_ws/install_isolated/env.sh', 'make', '-j4', '-l4']' returned non-zero exit status 2

What do I do to fix it? Thanks!

It looks like a version error, I have libuvc-0.0.5 from brew.

[gunshi]

Will downgrading libuvc to a lower version to test if this package builds, lead to errors with the already built ROS that I have?

[pdvelez]

I'm facing the same issue.

OS X Yosemite 10.10.5 ROS indigo brew libuvc version 0.0.5

EDIT: I was able to compile it by uninstalling brew libuvc, and installing it using cmake. https://int80k.com/libuvc/doc/index.html

[gunshi]

Hi, I just wanted to ask, why not libuvc_ros, and why libuvc? I mean in which case is installing the latter recommended?

[pdvelez]

Hi, actually I installed libuvc_ros but it worked only after installing libuvc.

This also solved it for me:

brew remove libuvc
git clone https://github.com/ktossell/libuvc.git
cd libuvc
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make && make install
