Hey guys im trying to get glut working with opengl but getting this error

The program has unexpectedly finished

Im using windows 10 qt 5 and freeglut for mvc3.0 and visual c++

QT       += core gui opengl
LIBS     += opengl32.lib -glu32
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

You need to put freeglut.dll next to your executable file.

Anyway, do you really need freeglut? It's very old and outdated. Qt already has built-in everything freeglut offers and more. It would be a lot easier to just use QOpenGLWidget.

Ok I have added it the freeglut.dll file into qtbuilds directory but still getting the program has unexpectedly finished.
and yea i just wanna get it working
i added the x64 from this folder
D:\ufilesD\freeglutMSVC\freeglut\bin\x64

INCLUDEPATH += D:/ufilesD/freeglutMSVC/freeglut/include
DEPENDPATH += D:/ufilesD/freeglutMSVC/freeglut/include

# currently removed -lfreeglut and just left freeglut
# because -lfreeglut is when the file is libfreeglut.dll
win32:CONFIG(release, debug|release): LIBS += -LD:/ufilesD/freeglutMSVC/freeglut/lib/x64/ -lfreeglut
else:win32:CONFIG(debug, debug|release): LIBS += -LD:/ufilesD/freeglutMSVC/freeglut/lib/x64/ -lfreeglut

LIBS     += -LGLU

i rearranged the pro file

i tried to use the debugger to the main.cpp on i see these segmentation fault

Ok I have added it the freeglut.dll file into qtbuilds directory

I said you need to put that dll next to the executable. From what I see in your output window the executable is in qtbuilds/debug/ folder, so place the dll there, not one directory up.

Hi,

Did you check that you have all dependencies required for the freeglut .dll if any ?
