I have installed Qt 5.1.1 on my windows 8 machine. I am compiling with mingw and want in link to gsl.
I set my paths to: C:\Program Files (x86)\GSL-1.13;C:\Qt\Tools\mingw48_32\bin
My pro file is QT += core
TARGET = gsl_test
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
SOURCES += main.cpp
using namespace std;
#include <gsl/gsl_sf_bessel.h> // gsl Bessel special function header file
double x = 5.0; // just a random test value
double y = gsl_sf_bessel_J0 (x); // see the GSL manual for details
cout << "J0(" << x << ") = "
<< setprecision(18) << setw(20) << y << endl;
The errors that I get are,
C:\Qt\Tools\QtCreator\bin\untitled\main.cpp:-1: error: undefined reference to `gsl_sf_bessel_J0'
collect2.exe:-1: error: error: ld returned 1 exit status
The compile output is,
18:07:33: Running steps for project untitled...

Error while building/deploying project untitled (kit: Desktop Qt 5.1.1 MinGW 32bit)
When executing step 'Make'
When I compiled this program using the command prompt with just MinGW I had an issue with permissions denied and would not create the .exe file unless I ran the command prompt as administrator. I ran qt creator as administrator but still got the same errors.
Anyone have any ideas on what it causing these errors?
Hi and welcome to devnet,
The problem probably comes from the space in your linker paths. General rule of thumb on Windows: no spaces in paths, they're evil. Even when quoting them properly, they can be problematic.
So you have two options there:
- Reinstall your dependencies in folders without spaces
- Use 8.3 names (you can get them using dir /x in a cmd prompt)
If you still have symbols error, check that you link to the correct libraries
Hope it helps

Yep, that did the trick.
You're welcome !
Now that it building correctly, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
