Hey OpenGL Programmers and C++ Users… I am new with OpenGL and this OpenGL Forum yet… So i use Dev C++ and i get installed FreeGLUT on Windows XP (at home i work on windows 7 and 10)… Now i try if opengl works on Dev C++, but no… i get an error!.. Just this is my script copied from google yet… ```auto #include void displayMe(void) { glClear(GL_COLOR_BUFFER_BIT); glBegin(GL_POLYGON); glVertex3f(0.0, 0.0, 0.0); glVertex3f(0.5, 0.0, 0.0); glVertex3f(0.5, 0.5, 0.0); glVertex3f(0.0, 0.5, 0.0); glEnd(); glFlush(); } int main(int argc, char** argv) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_SINGLE); glutInitWindowSize(300, 300); glutInitWindowPosition(100, 100); glutCreateWindow("Hello world :D"); glutDisplayFunc(displayMe); glutMainLoop(); return 0; } ``` Now i get an error in the returning function, so this is the error i get: > ## Compiling single file… > > - Filename: C:\Documents and Settings\Eigenaar\Bureaublad\GLUT Test.cpp > - Compiler Name: TDM-GCC 4.9.2 32-bit Release > > ## Processing C++ source file… > > - C++ Compiler: C:\Program Files\Dev-Cpp\MinGW64\bin\g++.exe > - Command: g++.exe “C:\Documents and Settings\Eigenaar\Bureaublad\GLUT Test.cpp” -o “C:\Documents and Settings\Eigenaar\Bureaublad\GLUT Test.exe” -m32 -I"C:\Program Files\Dev-Cpp\MinGW64\include" -I"C:\Program Files\Dev-Cpp\MinGW64\x86\_64-w64-mingw32\include" -I"C:\Program Files\Dev-Cpp\MinGW64\lib\gcc\x86\_64-w64-mingw32\4.9.2\include" -I"C:\Program Files\Dev-Cpp\MinGW64\lib\gcc\x86\_64-w64-mingw32\4.9.2\include\c++" -L"C:\Program Files\Dev-Cpp\MinGW64\lib32" -L"C:\Program Files\Dev-Cpp\MinGW64\x86\_64-w64-mingw32\lib32" -static-libgcc -m32 > C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x1c): undefined reference to `_imp ____ glutInitWithExit@12' C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x3e): undefined reference to `\_imp\_\_\_\_glutCreateWindowWithExit@8’ > C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x60): undefined reference to `_imp ____ glutCreateMenuWithExit@8' C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x7b): undefined reference to `\_imp\_\_glClear@4’ > C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x8c): undefined reference to `_imp__glBegin@4' C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0xb0): undefined reference to `\_imp\_\_glVertex3f@12’ > C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0xd4): undefined reference to `_imp__glVertex3f@12' C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0xf8): undefined reference to `\_imp\_\_glVertex3f@12’ > C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x11c): undefined reference to `_imp__glVertex3f@12' C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x126): undefined reference to `\_imp\_\_glEnd@0’ > C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x12d): undefined reference to `_imp__glFlush@0' C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x168): undefined reference to `\_imp\_\_glutInitDisplayMode@4’ > C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x181): undefined reference to `_imp__glutInitWindowSize@8' C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x19a): undefined reference to `\_imp\_\_glutInitWindowPosition@8’ > C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x1ba): undefined reference to `_imp__glutDisplayFunc@4' C:\DOCUME~1\Eigenaar\LOCALS~1\Temp\ccDvQv6O.o:GLUT Test.cpp:(.text+0x1c4): undefined reference to `\_imp\_\_glutMainLoop@0’ > collect2.exe: error: ld returned 1 exit status > > ## Compilation results… > > - Errors: 1 > - Warnings: 0 > - Compilation Time: 1,17s I am an newbie with OpenGL and i use Dev C++ for it…, Please can anyone help me to correct my code ?..

Your link line is missing references to the GLUT and OpenGL libraries. Try adding the arguments “-lglut32 -lopengl32”. If you still have unresolved “glut” symbols", try -lfreeglut instead of -lglut32. For more possible solutions, websearch “devc++ glut unresolved reference”. For instance: [ul] [li][Undefined references using GLUT with MinGW](https://stackoverflow.com/questions/14411960/undefined-references-using-glut-with-mingw) [/li][/ul]
