Question

我目前在使用SDL2 TTF模块时出现问题，我使用sudo apt-get安装了dev文件，并使用了CMake

这是我的代码：

#include "SDL.h"
#include "SDL_image.h"
#include "SDL_ttf.h"

int main(){
    SDL_Init(SDL_INIT_EVERYTHING);
    IMG_Init(IMG_INIT_PNG);
    TTF_Init();
    return 0;
}

这是我的CMakeLists.txt文件。

cmake_minimum_required (VERSION 3.5)

project (MyProject)

set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Werror -Wno-unused-variable -std=c++14")
set (source_dir "${PROJECT_SOURCE_DIR}/src/")

file (GLOB source_files "${source_dir}/*.cpp")

add_executable (MyProject ${source_files})

INCLUDE(FindPkgConfig)

PKG_SEARCH_MODULE(SDL2 REQUIRED sdl2)
PKG_SEARCH_MODULE(SDL2IMAGE REQUIRED SDL2_image>=2.0.0)
PKG_SEARCH_MODULE(SDL2TTF REQUIRED SDL2_ttf>=2.0.0)

INCLUDE_DIRECTORIES(${SDL2_INCLUDE_DIRS} ${SDL2IMAGE_INCLUDE_DIRS} ${SDL2TTF_INCLUDE_DIRS})
TARGET_LINK_LIBRARIES(${PROJECT_NAME} ${SDL2_LIBRARIES} ${SDL2IMAGE_LIBRARIES} ${SDL2TTF_LIBRARIES})

这是输出
