未定义的引用 '[从GLEW库中各种事物]'联GLEW与MinGW64 - 未定义参考`__imp_glewExperimental”和'__imp___glewGenVertexArrays'
这是我的CMakeLists.txt：
cmake_minimum_required(VERSION 3.7)
project(newerOpenGLTest)
set(CMAKE_CXX_STANDARD 11)
set(SOURCE_FILES main.cpp)
add_executable(newerOpenGLTest ${SOURCE_FILES})
find_package(OpenGL)
# tell it where to look for glew
set(CMAKE_PREFIX_PATH "F:/glew-2.0.0")
set(CMAKE_LIBRARY_PATH "F:/glew-2.0.0/lib/Release/x64")
find_package(GLEW REQUIRED)
if (GLEW_FOUND)
message(${GLEW_INCLUDE_DIRS})
message(${GLEW_LIBRARIES})
# Detect and add SFML
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake_modules" ${CMAKE_MODULE_PATH})
#Find any version 2.X of SFML
#See the FindSFML.cmake file for additional details and instructions
find_package(SFML 2 REQUIRED graphics window system)
if(SFML_FOUND)
include_directories(
${GLEW_INCLUDE_DIRS}
${SFML_INCLUDE_DIR}
)
target_link_libraries(
newerOpenGLTest
${GLEW_LIBRARIES}
${SFML_LIBRARIES}
${SFML_DEPENDENCIES}
${OPENGL_gl_LIBRARY}
)
endif()
endif()
这是C进行输出：
F:/glew-2.0.0/include
F:/glew-2.0.0/lib/Release/x64/glew32.lib
-- Found SFML 2.4.2 in F:/SFML-2.4.2 for GCC 6.1.0 MinGW (SEH) - 64-bit/include
-- Configuring done
-- Generating done
-- Build files have been written to: F:/Users/Doug/CLionProjects/newerOpenGLTest/cmake-build-debug
一切看起来鳍我在那里。它找到GLEW并找到包含文件和库的位置。
这是我的main.cpp：
#include <GL/glew.h>
#include <SFML/Window.hpp>
int main() {
sf::Window window(sf::VideoMode(800, 600), "openGL");
window.setVerticalSyncEnabled(true);
window.setActive(true);
// Initialize GLEW
glewExperimental = true;
if (glewInit() != GLEW_OK) {
fprintf(stderr, "Failed to initialize GLEW\n");
return -1;
}
GLuint VertexArrayID;
glGenVertexArrays(1, &VertexArrayID);
glBindVertexArray(VertexArrayID);
bool running = true;
while (running) {
sf::Event event;
while (window.pollEvent(event)) {
if (event.type == sf::Event::Closed) {
running = false;
}
}
}
return 0;
}
这里是从连接的输出：

未定义参考3个GLEW元件。
注意，它并没有说undefined reference to '__imp_glewInit'
所以它是连接一些GLEW的，但不是万能的。
我运行glewinfo.exe和输出有glGenVertexArrays: OK 我认为这意味着我的驱动程序支持该功能。
