Sample example for control Galil motion controller Using Qt Programs

Vijay Lamkane

i m new to this topic can any ane help me to send or receive data from galilPCI controller to Qt program and Qt program to Gallil Controller

mrjj

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

Vijay Lamkane

@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

Vijay Lamkane

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

jsulm

@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).

Vijay Lamkane

@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

INCLUDEPATH += $$PWD/../../../../usr/include
DEPENDPATH += $$PWD/../../../../usr/include

@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.

Vijay Lamkane

ile /usr/lib/../lib/libGalil.so

/usr/lib/../lib/libGalil.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, BuildID[sha1]=43f20bd8e5cbb6aff96819c8376887d030ac4f19, stripped

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

jsulm

@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.

Vijay Lamkane

after building only galilConnection4.pro file

:-1: error: No rule to make target 'galilConnection4.o'. Stop.

SGaist

What's in that .pro file ?
