我正试图在Ubuntu 20.04上集成librealsense C CLion项目。< br >在终端中单独编译Librealsense可以正常工作。
项目如下所示:
RS_Pipeline . ├── build ├── main.cpp ├── CMakeLists.txt └── librealsense // the integrated lib ├── CMakeLists.txt ├── third-party // libs like GLFW and GLAD which are use in the examples ├── examples // | ├── example.hpp // with class to generate OpenGL Window └── ...
克马尔主义者。基本文件夹中的txt看起来相当简单:
cmake_minimum_required(VERSION 3.2) project(RS_Pipeline LANGUAGES CXX C) set(CMAKE_CXX_STANDARD 11) set(OpenGL_GL_PREFERENCE LEGACY) add_executable(RS_Pipeline main.cpp librealsense/examples/example.hpp) add_subdirectory(librealsense) target_link_libraries(${PROJECT_NAME} realsense2)
当我试图将子模块包含到我的CLion项目中时,我得到了大量的:< code>main.cpp:(。text 0x23c):对glViewport错误消息的未定义引用,在基目录中构建my main.cpp失败。
不知何故<代码> #包含
另外:librealsense库中包含的示例也可以毫无问题地编译。(他们使用完全相同#include“librealsense/examples/example.hpp”。
看起来,CLion只是没有在我自己的main中找到正确的openGL。分别为cpp。如果我从example.hpp中包含它。

@Botje多谢了,真快!现在,它正在与以下CMakeLists合作:
cmake_minimum_required(VERSION 3.2) project(RS_Pipeline LANGUAGES CXX C) set(CMAKE_CXX_STANDARD 11) set(OpenGL_GL_PREFERENCE LEGACY) find_package(OpenGL REQUIRED) add_executable(RS_Pipeline main.cpp librealsense/examples/example.hpp) add_subdirectory(librealsense) target_link_libraries(${PROJECT_NAME} realsense2 glfw OpenGL::GL glfw OpenGL::GLU )
看起来这个话题已经可以结束了。
这些示例都包含此文件,而您没有:
find_package(OpenGL REQUIRED)
set(DEPENDENCIES realsense2 glfw ${OPENGL_LIBRARIES})
这使得< code>realsense2库依赖于GLFW和您的OpenGL堆栈。
将以下内容添加到CMakeLists.txt中:
find_package(OpenGL REQUIRED)
target_link_libraries(${PROJECT_NAME} glfw OpenGL::GL )
我只是想让OpenGL在我的机器(Windows 7 64位)上使用GLFW工作。 我得到了单一的链接器错误: 我试图编译的代码是最简单的(在Test.cpp文件中)。 我正在使用一个简单的Makefile来尝试编译: 其他信息: 使用g编译(MinGW32) lib文件夹包含glfw3.dll、libglfw3. a和libglfw3dll. a(从GLFW网站下载的Win32版本-Window
