Linux下OpenGL的安裝與cmake編譯OpenGL程序

OpenGL安裝

安裝命令如下：

$ sudo apt install build-essential

$ sudo apt install libgl1-mesa-dev

$ sudo apt install libglu1-mesa-dev

$ sudo apt install freeglut3 freeglut3-dev

cmake編譯OpenGL程序

project

├── MeshLib

│ └── core

│ └── bmp

│ └── RgbImage.cpp

├── MyDemo

│ ├── main.cpp

│ ├── CMakeLists.txt

│ └── build

│

其他頭文件的路徑直接在.cpp里體現出來，如：

在main.cpp中：

#include

#include"../MeshLib/core/viewer/Arcball.h"

#include"../MeshLib/core/bmp/RgbImage.h"

#include"../MeshLib/core/Geometry/quat.h"

否則，如果直接寫 #include “Arcball.h” 之類的，就需要在CMakeLists.txt中包含所有頭文件路徑(如glut.h就需要指定路徑 OpenGL_INCLUDE_DIR)

若使用freeglut的話

MyDemo/CMakeLists.txt

cmake_minimum_required(VERSION 2.6)

add_compile_options(-std=c++11)

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_CURRENT_SOURCE_DIR}/build/CMakeModules/")

project(MyDemo)

find_package(OpenGL REQUIRED)

include_directories(${OpenGL_INCLUDE_DIR})

find_package(FREEGLUT REQUIRED)

include_directories(${FREEGLUT_INCLUDE_DIR})

add_executable(${PROJECT_NAME} ${PROJECT_BINARY_DIR}/../../MeshLib/core/bmp/RgbImage.cpp main.cpp )

target_link_libraries(${PROJECT_NAME} ${OPENGL_LIBRARY} ${FREEGLUT_LIBRARY} ${OPENGL_LIBRARY})

但是光這樣還是沒辦法的，因為找不到freeglut庫，這時候需要再寫一個搜索package frerglut的CMakeLitsts.txt

在build目錄下mkdir一個CMakeModules, 新建一個文件名FindFREEGLUT.cmake的文件，編輯內容如下(為什么是在build目錄下新建而不是在MyDemo目錄下？因為我們是進入build中，執行命令”cmake ..“的)

# Try to find the FREEGLUT library

#

# FREEGLUT_INCLUDE_DIR

# FREEGLUT_LIBRARY

# FREEGLUT_FOUND

FIND_PATH(

FREEGLUT_INCLUDE_DIR GL/freeglut.h GL/gl.h GL/glu.h GL/glew.h

${CMAKE_INCLUDE_PATH}

$ENV{include}

${OPENGL_INCLUDE_DIR}

/usr/include

/usr/local/include

)

SET(STORE_CMAKE_FIND_FRAMEWORK ${CMAKE_FIND_FRAMEWORK})

SET(CMAKE_FIND_FRAMEWORK NEVER)

FIND_LIBRARY(

FREEGLUT_LIBRARY

NAMES freeglut_static freeglut glut GL

PATH

/opt/local/lib

${CMAKE_LIBRARY_PATH}

$ENV{lib}

/usr/lib

/usr/local/lib

)

SET(CMAKE_FIND_FRAMEWORK ${STORE_CMAKE_FIND_FRAMEWORK})

IF (FREEGLUT_INCLUDE_DIR AND FREEGLUT_LIBRARY)

SET(FREEGLUT_FOUND TRUE)

ENDIF (FREEGLUT_INCLUDE_DIR AND FREEGLUT_LIBRARY)

IF (FREEGLUT_FOUND)

IF (NOT FREEGLUT_FIND_QUIETLY)

MESSAGE(STATUS "Found FREEGLUT: ${FREEGLUT_LIBRARY}")

ENDIF (NOT FREEGLUT_FIND_QUIETLY)

ELSE (FREEGLUT_FOUND)

IF (FREEGLUT_FIND_REQUIRED)

MESSAGE(FATAL_ERROR "Could not find FREEGLUT")

ENDIF (FREEGLUT_FIND_REQUIRED)

ENDIF (FREEGLUT_FOUND)

若使用glut的話

則則比較簡單：

cmake_minimum_required (VERSION 2.6)

project(OpenGL)

find_package(OpenGL REQUIRED)

include_directories(${OPENGL_INCLUDE_DIR})

find_package(GLUT REQUIRED)

include_directories(${GLUT_INCLUDE_DIR})

set(CMAKE_CXX_FLAGS "-g -Wall")

add_executable(OpenGL Main.cpp)

target_link_libraries(OpenGL ${GLUT_LIBRARY} ${OPENGL_LIBRARY})

可能出現的錯誤

if you use `-fpermissive’, G++ will accept your code, but allowing the use of an undeclared name is deprecated

解決方法 add_compile_options(-fpermissive -std=c++11)

undefined reference to symbol …

這類錯誤通常是鏈接.so, .a文件失敗產生的，但是都會給出具體是哪個lib沒有：”/lib/x86_64-linux-gnu/libz.so: error adding symbols: DSO missing from command line”

解決方法，

1.用各種方法把libz.so放到指定目錄下(方法太多了自行查詢)

2.若目錄下已有libz.so，則在target_link_libraries中加上該libz.so( ${PROJECT_SOURCE_DIR}//libz.so)
