My system is Windows vista and I have installed the newest version of MinGW to compile the project. then set the permission of your file to 777 then execute it. I've been making my way through the CUDA by example book but hit a snag. It says there's an undefined reference to 'Card::Card()', undefined reference to 'pcl::PCDWriter::resetLockingPermissions(std::basic_string<char,std::char_traits<char . But it returns some 'Undefined References' to all the functions that i have used in my pgm. I attempting following the guide at ntu's Programming OpenGL in C/C++ (I can't link it due to an inadequate post count) site and added the freeglut, glu32 and opengl32 libraries, although there are still several undefined references and the bad reloc address remaining. sudo apt-get install freeglut3 sudo apt-get install freeglut3-dev sudo apt-get install libxmu-dev sudo apt-get install libxi-dev dpkg -L freeglut3-dev. Hello there! undefined reference to 'glClearColor@16' undefined reference to 'glClearDepth@8' undefined reference to 'glClear@4' undefined reference to 'glClearDepth@8' undefined reference to 'glClear@4' VERSIONS AND COMPUTER SPECS IDE: Code Blocks 16.0.1 SDL: SDL2-2.0.4 GLEW: glew-1.13.0 Operating System: Windows 7 LINKING: glew32s.lib glew32.lib. The trick is to remember that if you use any functions from included header files that …. 楼主找不到的这些函数实现，比如glClear，都在 libopengl32.a 里面，链接时加上 -lopengl32 应该就行了。 另外 MinGW 的 OpenGL 不含 glut . So add -lglaux -lglu32 -lglut32 to the linker options. I tried example 1.2 "hello" but i have lots of [linker error] undefined reference to. Here is what I get from the compiler: Water.o(.text+0x2aa):Water.cpp: undefined reference to _imp__glPolygonMode' Water.o(.text+0x2b8):Water.cpp: undefined reference to_imp__glEnable' Water.o(.text+0x2d0):Water.cpp: undefined reference to _imp__glPolygonMode' Water.o(.text+0x2de):Water.cpp . undefined reference to 'glClear'. After I switched to MinGW64 I still got some errors. In there, you would need to add glee.lib, glut32.lib, libopengl32.a and libglu32.a. Here are the commands I have tried so far. Sorry for the horrible formatting, I don't know why the text has turned a large size and has been cropped. I attempting following the guide at ntu's Programming OpenGL in C/C++ (I can't link it due to an inadequate post count) site and added the freeglut, glu32 and opengl32 libraries, although there are still several undefined references and the bad reloc address remaining. undefined reference to 'glColor3f'. voila mon problème , j'ai eu l'erreur ' undefined reference to ' malgré que j'ait cernais tout les probs , dans mon projet j'ai deux fichiers source (main.c et exo_joueurs.c ) et j'ai aussi le fichier header (exo_joueurs.h),bref mon code lis. Thank you for your time. But this time other errors. - Errors or unexpected behaviour. Postby lucebac » Sun Aug 27, 2017 4:47 pm. c++ - Undefined references [SOLVED] | DaniWeb. rahul@rahul-System-Product-Name:~$ g++ -lGL -lGLU -lglut nrs1.c /tmp/ccIsCRgh.o: In function `myInit ()': nrs1.c: (.text+0x2a): undefined reference to `glClearColor' nrs1.c: (.text+0x37): undefined reference to `glPointSize' nrs1.c: (.text+0x43 . You will presumably have something like this then: In there, you would need to add glee.lib, glut32.lib, libopengl32.a and libglu32.a. Using Windows 8.1, Code::Blocks 13.12 (MinGW 32), GLFW 3.0.4 0. Try using this: g++ -LC:/MinGW/lib helloGL.cpp -lopengl32 -lglu32 -lglut32. Clockowl 56 Posting Whiz. raw download clone embed print report. Hi, I am new on using ubuntu with g++. Salut, Bon, je ne vais pas répéter la plus grosse partie d'un message que je n'ai écrit qu'il y a quelques heures. 0. Ah yes, I am trying to program using OpenGL (should've mentioned that earlier). I am getting undefined reference errors. Similar problem to this, except I'm not using CMake. undefined reference to 'glLineWidth'. Every time when I build the source code I get the following errors: D:\c++_project\build-OGLQuad-Des. I have used the following command to compile the : clang++ main.cpp -lglfw -lGL -lX1 … Remarks. I'm making sure to link to opengl32 and glu32 . Likewise if you need glut or glu library functions you want -lglut -lglu respectively. g++ -o olcExampleProgram olcExampleProgram.cpp -lX11 -lGL -lpthread -lpng -lstdc++fs. i installed the dev pack for glut so i thing this is not the problem and i think i have not to add some lib to linklist in project->options etc etc. Re: Linker error: undefined reference to symbol 'glClear'. Hello everyone, I am attempting to compile my first OpenGL program, but I run into the following errors: $ gcc hellok.c hellok.c:49:2: warning: no newline at end of file /tmp/ccQrLcMW.o(.text+0xe): In function `display': : undefined reference to `glClear' /tmp/ccQrLcMW.o(.text+0x2d): In function `display': : undefined reference to `glColor3f . 3)In the other linker options, add this code, exactly as it is below: I'm completely new to OpenGL, and still relatively new to programming. For almost any file in my 'Include' headers, I make sure I have the right '.lib' file listed. I know similar questions exist, but I have pretty much looked at all of them and I couldn't find an answer that worked. Compiling a "hello world" program works like a charm. Here is the code I'm using and to compile I'm using this command (I'm following the tutorial as it's written) g++ -std=c++11 -o main -lglfw -lGLEW -lGL main.cpp. You need to link to the GL library.

Open the codeblocks editor and open your file/project. Hi, I am new on using ubuntu with g++. Also, I'm not sure about the prebuilt libraries with MinGW. I am able to run the sample bump.c code in tutorial section both in serial and parallel. text 0.67 KB. 0. Goto Project->Build Options. You need to start using both. I'm going to go out on a limb here and say it's got something to do with you not telling it which directories to look in for the libraries (I've had quite a few issues with it myself, which is why I just get CodeBlocks to do everything for me now). After compiling this I get the exact undefined references as my engine. 120. the most functions that he probably does not recognise have prefix gl what i have to do ? But trying to compile with them throws me compile errors like undefined reference to 'glad_debug_glClearColor' and undefined reference to 'glad_debug_glClear'. Welcome! Answered by Stinomus 11 in a post from 12 Years Ago. It's possible I'm missing something basic and/or obvious here. Update: Installed other version of MinGW, this time gcc --version gives me MinGW.org GCC-6.3.0-1 instead of x86_64-posix-seh-rev0, still not working . I'm compiling the lastest SFML (commit 4a30054) from source with MinGW which goes fine (I guess -- I get .a files) for use in CodeBlocks (CB). Just to make things clear, its supposed to be compiled as nvcc julia_gpu.cu -lglut -lGLU -lGL. .objs\main.o:main.c:(.text+0x48): undefined reference to `glClear@4' > clairement une mauvaise configuration du linkage. You're specifying a file. g++ ./path/to/files.cpp ./path/to/allfile.cpp -o outputfile -lGL -lglut. The projects hirachy. Compiling a "hello world" program works like a charm. I fixed them by compiling it with This isn't specific to OpenGL, linking is necessary for pretty much every library you'll ever use. [Linker error] undefined reference to glClear@4' [Linker error] undefined reference toglColor3f@12' I had the code: #include <cstdlib> #include <iostream> #include <GL/gl.h> #include <GL/glu.h> #include <GL/glut.h> #include <windows.h> #include <stdlib.h> #include <stdio.h> #include <vector> // #include <libiberty.h> using namespace std; int . These provide OpenGL support for the example programs that use OpenGL. (Be aware the forums do not accept user names with a dash "-") Also, logging in lets you avoid the CAPTCHA verification when searching . Relire le cours de M@teau sur la SDL (comment rajouter des options à l'édition des liens) + donc rajouter -lopengl32 Meme sans carte 3D ça compile. If this is your first visit, be sure to check out the FAQ.You will have to register before you can post in the forums. I have tried switching the position of the libraries around as this had fixed previous issues . #!/bin/bash. stefu. I understand this could result from a number of issues including a compiler mismatch, but I wanted to ask here to make sure I wasn't just doing something wrong linking. Oftentimes projects will only supply prebuilt MSVC binaries for Windows. For GLUT, it needs 'glut32.lib', etc. Hi @harshmittal2210 The first thing I would like to check if whether you built librealsense from source code. Goto "Project"->"Project Options" and add to the Linker Options/Optional Libraries line following: -lopengl32 -lglu32. The glClear function sets the bitplane area of the window to values previously selected by glClearColor, glClearIndex, glClearDepth, glClearStencil, and glClearAccum.You can clear multiple color buffers simultaneously by selecting more than one buffer at a time using glDrawBuffer.. i have tried to compile the code using nvcc heat.cu -o heat but i am getting a ton of errors … The glClear function sets the bitplane area of the window to values previously selected by glClearColor, glClearIndex, glClearDepth, glClearStencil, and glClearAccum.You can clear multiple color buffers simultaneously by selecting more than one buffer at a time using glDrawBuffer.. Using Visual C++, I check under Project->Settings, and hit the Link tab. Cancel. so every time when i use openGL i should put those flags Yes. Hi, please help. I'm trying to compile this: For example, for #include <gl/gl.h> I make sure I have 'opengl32.lib' referenced. Probably related: #21299.
