Sample example for control Galil motion controller Using Qt Programs

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).

@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.

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 ?
