Hi
Maybe from here ?
http://www.galilmc.com/downloads/api
Download the SDK for your platform.
There should be samples for c++.
It seems not to have direct support for Qt but the c++
should work.

The quick start seems good place to start ;)

@Vijay-Lamkane said in Sample example for control Galil motion controller Using Qt Programs:

galilPCI

See here: http://www.galilmc.com/downloads/api
You can use their gclib C library to access the controller. There are examples.
See here how to use shared libraries with QtCreator: http://doc.qt.io/qtcreator/creator-project-qmake-libraries.html

@mrjj
thanks for yor kind reply , i already tried to this link for download and install gclib but url is not working .also i had gone through the getting url mannulay from their website and but it not works

@jsulm thanks
but i fail to downlod gclib library ,i used http://www.galilmc.com/sw/pub/all/doc/gclib/html/ubuntu.html
but the url is not working

currently i am using Galil.h file
but stuck here
#include <QCoreApplication>
#include <Galil.h>

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);

Galil g("192.168.1.100");

return a.exec();

}

gives errors like
error: undefined reference to `Galil::Galil(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'

/home/system/Qt_Programs/galilConnection3/main.cpp:8: error: undefined reference to `Galil::~Galil()'

how can i solve it

@Vijay-Lamkane The URL is working for me.
It is not enough to include the header file: you have to link against the library (*.so).

@jsulm

.pro file

QT += core
QT -= gui

TARGET = galilConnection3
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

unix:!macx: LIBS += -L$$PWD/../../../../usr/lib/ -lGalil

@Vijay-Lamkane Are you building for x86 or x86_64? Is the library built for x86 or x86_64? You can check calling

file /usr/lib/../lib/libGalil.so

on the command line.
Post here what file /usr/lib/../lib/libGalil.so prints.

@jsulm
is there need of controller to be connected while testing the given program ?

jsulm · 21 Oct 2016, 11:19

@Vijay-Lamkane For testing yes but not to build it. You're current problem isn't related to connected/not connected controller.

The lib is x86, so I guess you're building for x86_64, is that correct? In this case you should either build for x86 or check whether this library is available as x86_64.

@jsulm
i had reinstalled lib file

#include <QCoreApplication>
#include <Galil.h>

#include <iostream> //cout
#include <sstream> //ostringstream istringstream
#include <vector>
#include <iostream>.h>
using namespace std;
int main(int argc, char *argv[])
{

//string address = "";
Galil g();
Galil *q;

cout << Galil::libraryVersion() << endl;

}

Output Error

/home/system/Qt_Programs/galilConnection3/main.cpp:17: error: undefined reference to `Galil::libraryVersionabi:cxx11'

Hi,

Looks like you are not linking to the library.

after building only galilConnection4.pro file

What's in that .pro file ?
