9 years ago Hi: In Netbeans IDE: -. Clean & Build project -. Run project This issue is because the native library did not find in the classpath. I'm investigating how package dylib in a jar file and run project from maven.

9 years ago hi cybercastle, thanks a major stack. this is an important feature for me and i am soooo itching to get this to work as it would allow me to start playing with my webcam from within my own project, rather than running a separate App from C for that. All of my Java (and C/C++) development is in eclipse and am not familiar with netbeans. Do i need to switch to netbeans to get this project to work or can i make it work in eclipse? Any help you could provide for getting me over this initial hump would be hugely appreciated. If you'd be willing to email me for a quick chat, I would be eternally grateful. my name is robert huber lobsterman.bgsu@gmail.com at the Radcliffe Institute in Boston.

9 years ago Hi Robert:
No need to use Netbeans. In eclipse it should also be possible to run the project. I will try pack the dylib in the jar file.

9 years ago hi cybercastle, i think i am stuck just ahead of that. i don't have a .jar file for the llibuvc as i am having problems compiling the downloaded jlibuvc source into the jar. do you know of a place where i can download the current jar or would you be willing to send me a copy of it? i then know how to set the dylib's native library location for the jar. thanks a stack

Using Homebrew (http://brew.sh/) install libuvc in your mac:
brew install jpeg (for jpeg support) brew install libuvc --HEAD (this version fixed a error in the header file)
And recompile the proyect again.

this means i now have the .jar and nothing can stop me now :-)
may i suggest that you add to the readme.md file the note to compile this into jLibUVC.jar by first changing into the directory where the pom.xml file is, then compile with maven using the command "mvn package". that would be really useful for folks like me who stumble into this from a very different background. ok, off i go back to actually writing code, rather than pulling my hair out.
thanks again, I owe you many beers if your travels ever bring you to the northern parts of the continent. be well,

the libuvc installation with dylib exists /opt/local/lib/ and works well with my libuvc examples in C. i am trying to get the java wrapper to work in its most simplified form and am running into link error ...

UVCController.uvc_init() throws ...

any suggestions greatly appreciated ...
