That requires the use of toolchains which is not supported by Raspbian. Is there any other way?

I would recommend searching these forums, I'm sure someone else has done it.

[axton900]

If anyone knows how, if they could explain the process of doing this or point me in the right direction, then I would be very grateful!

Thanks!!

I was able to do it a while ago. As long as you are running the lastest raspbian, it should have GCC 4.9, and compile correctly. It just takes a while. You might have to use cmake, I don't remember.

As Thad said, you can compile directly on the Raspberry Pi. CMake is definitely the easier option.

Should be something like:

cd ntcore
cmake .
make
sudo make install

Then when you compile you would add the "-lntcore" flag to G++.

I remember Java giving some trouble with compiling. If it does run "cmake . -DWITHOUT_JAVA=true" instead.

Thanks for the help! We really appreciate it!

There is a version of ntcore built for the Raspberry Pi 2/Debian for use with GRIP. You might want to look at:

I'm running into an error after installing and compiling and using the -lntcore prefix but I'm getting the error, "error while loading libraries, libntcore.so.1 cannot open shared object file: No such file or directory" What should I do?

[simon-andrews]

You need to append /usr/local/lib to your library path. CMake installs libntcore.so to /usr/local/lib which is not on the library path by default. This answer on StackOverflow answers the question better than I can.

Sorry for the late response and I hope this helps!

I have a quick question for you. Depending on your response, I might have an alternate solution that works well for us.
I believe I know the answer, but the question is, are you running your RPi on the robot? In other words, are you doing your vision processing on the RPi on the robot.?

[axton900]

Yes, yes we are. We seemed to have it working now but we are eager to hear your alternate solution Sorry for the late response!!
