LNK2019 error still, after added libraries to linker additional dependencies

2020-09-23T19:12:32+00:00

Hi,

I was trying to start up a new simple project with GUI in a new solution using the bullet library. I created this solution by adding existed porjects (Bullet3Common, BulletCollision, BulletDynamics, LinearMath, and OpenGL_Window). Initially I was having a lot of linking errors but I resolved some of them by reading lots of posts here (thanks!), here's what I have done so far:

I added those imported projects as References, to set up project dependencies

I added the libraries path to my linker, specifically in "Configuration properties->Linker->Input->Addtional Dependencies", like below

../../bullet3-master/bin/Bullet3Common_vs2010_debug.lib
../../bullet3-master/bin/BulletCollision_vs2010_debug.lib
../../bullet3-master/bin/BulletDynamics_vs2010_debug.lib
../../bullet3-master/bin/LinearMath_vs2010_debug.lib
../../bullet3-master/bin/OpenGL_Window_vs2010_debug.lib

However, I'm still getting LNK2019 error somewhere:

Code:

ErrorLNK2019unresolved external symbol "public: __thiscall OpenGLGuiHelper::OpenGLGuiHelper(struct CommonGraphicsApp *,bool)" (??0OpenGLGuiHelper@@QAE@PAUCommonGraphicsApp@@_N@Z) referenced in function _mainApp_ExampleApp_Example.obj1ErrorLNK2019unresolved external symbol "public: virtual __thiscall OpenGLGuiHelper::~OpenGLGuiHelper(void)" (??1OpenGLGuiHelper@@UAE@XZ) referenced in function _mainApp_ExampleApp_Example.obj1ErrorLNK2019unresolved external symbol __imp__wglCreateContext@4 referenced in function "protected: void __thiscall Win32OpenGLWindow::enableOpenGL(void)" (?enableOpenGL@Win32OpenGLWindow@@IAEXXZ)App_ExampleOpenGL_Window_vs2010_debug.lib(Win32OpenGLWindow.obj)1ErrorLNK2019unresolved external symbol __imp__wglDeleteContext@4 referenced in function "protected: void __thiscall Win32OpenGLWindow::disableOpenGL(void)" (?disableOpenGL@Win32OpenGLWindow@@IAEXXZ)App_ExampleOpenGL_Window_vs2010_debug.lib(Win32OpenGLWindow.obj)1ErrorLNK2019unresolved external symbol __imp__wglMakeCurrent@8 referenced in function "protected: void __thiscall Win32OpenGLWindow::disableOpenGL(void)" (?disableOpenGL@Win32OpenGLWindow@@IAEXXZ)App_ExampleOpenGL_Window_vs2010_debug.lib(Win32OpenGLWindow.obj)1ErrorLNK11205 unresolved externalsApp_ExampleApp_Example.exe1

There seems to be something wrong with OpenGL_Window_vs2010_debug.lib?
Did anyone have similar problems?

update:
I manually added these source files to my project:

"examples/ExampleBrowser/OpenGLGuiHelper.cpp"
"examples/ExampleBrowser/GL_ShapeDrawer.cpp"
"examples/ExampleBrowser/CollisionShape2TriangleMesh.cpp"
"examples/ThirdPartyLibs/glad/gl.cpp"

I got following new link errors:

Code:

Looks like it cannot resolve btShapeHull, btCollisionShape, etc... which should be included in the libraries? I don't understand
