Undefined symbols for architecture x86_64

For the following code:

#include <GL/glew.h>
#include <GLFW/glfw3.h>
#include <stdio.h>

int main() {
    // start GL context and O/S window using the GLFW helper library
    if (!glfwInit()) {
        fprintf(stderr, "ERROR: could not start GLFW3\n");
        return 1;
    }
    // uncomment these lines if on Apple OS X
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    GLFWwindow *window = glfwCreateWindow(640, 480, "Hello Triangle", NULL, NULL);
    if (!window) {
        fprintf(stderr, "ERROR: could not open window with GLFW3\n");
        glfwTerminate();
        return 1;
    }
    glfwMakeContextCurrent(window);
    // start GLEW extension handler
    glewExperimental = GL_TRUE;
    glewInit();
    // get version info
    const GLubyte *renderer = glGetString(GL_RENDERER);
    const GLubyte *version = glGetString(GL_VERSION);
    printf("Renderer: %s\n", renderer);
    printf("OpenGL version supported %s\n", version);
    // tell GL to only draw onto a pixel if the shape is closer to the viewer
    glEnable(GL_DEPTH_TEST); // enable depth-testing
    glDepthFunc(GL_LESS); // depth-testing interprets a smaller value as "closer"
    /* OTHER STUFF GOES HERE NEXT */
    // close GL context and any other GLFW resources
    glfwTerminate();
    return 0;
}

And the following conanfile:

[requires]
glew/2.1.0@bincrafters/stable
glfw/3.3@bincrafters/stable

[generators]
cmake

And following the tutorial for running conan on CLion, when I debug it executes the following command:

"/Users/brianyeh/Library/Application Support/JetBrains/Toolbox/apps/CLion/ch-0/192.7142.39/CLion.app/Contents/bin/cmake/mac/bin/cmake" --build /Users/brianyeh/CLionProjects/glfw_template/cmake-build-debug --target glfw_template -- -j 4

which generates the following error:

Am I doing something wrong or is this an issue with conan or the libraries? Also I’m running this on OSX.

It’s a linking issue, profile seems alright. Have you tried the https://github.com/lasote/clion-conan-consumer? I also noticed that the tutorial doesn’t mention this line: https://github.com/lasote/clion-conan-consumer/blob/master/CMakeLists.txt#L13 Please make sure you have it in your CMakeLists.

Thanks a lot, @Minimonium, for attending this issue ❤️

I think it’s been resolved, but feel free to open it again if needed.

Thanks!
