RB-100 Lubuntu gcc/g++ use roboard libraries

[krokido]

Hi

I have installed the Lubuntu image, as supplied by Roboard on their website, onto the roboard RB-100. works great!
I can make a simple 'hello world' program in C++ using G++ as compiler
But as soon as I want to use Roboard specific functionality, such as 'roboio_SetRBVer(RB_100)', I get the following error message from g++:
'undefined reference to 'roboio_SetRBVer' colelct2: ls returned 1 exit status'

I am having troubles with making/installing/placing the RoBoIO library... I don't know where to put what and how ... a general lack of knowledge on my part here ...

I have very little experience with Linux and g++ so ... 'newbyproof' answers are highly appreciated!

The code I made:

Code: Select all

#include <iostream>
#include <stdio>
#include <string>
#include <stdlib>
#include "roboard.h"

using namespace std;

int Add(int x, int y)
{   
   return(x+y);
}

int main()
{
   roboio_SetRBVer(RB_100);

   int a, b, c;

   cout << "Hello World!" << endl;
        cout << "give the two numbers to add;" <<endl>> a;
   cin >> b;
   c = Add(a, b);
   cout << "a + b = " << c << endl;
   return 0;
}

Hi,

please go to http://www.roboard.com/download_ml.htm and download "RoBoIO 1.81 binary for for Debian & Ubuntu".

Extract it and then you can find Linux makefile examples for RoBoIO in the "Examples" directory.

Great!

compiling now works! indeed the answer is in the make files

Code: Select all

pwm.exe : pwm.o
   gcc -o pwm.exe pwm.o -L../../Lib -lRBIO -lstdc++
pwm.o : pwm.cpp
   gcc -c pwm.cpp -I../../Include

.PHONY : clean
clean :
   -rm pwm.o pwm.exe


I didn't the -L and -I options resulting in the error. Now the code runs smoothly ... but, using

Code: Select all

sudo -i
./pwm.exe


Does not move my Robbe Futaba S3003 which is connected to either port S1 and or S2 ... I'll look at that again tonight

Thank you RoBoard!

And the Robbe Futaba s3003 servos also move!

DMP Roboard, awesome job! Great product and great support!

greetings from a happy newby!
