Question

我在Windows上使用带有MinGW（gcc / g ++）的CLion。我花了几个小时研究为什么我不能编译简单的程序，因为我有链接所有内容的问题。

我尝试将所有找到的解决方案结合在互联网上，应用了有助于其他人的变化。我仍然会遇到问题。

这是我的main.cpp：

#include <iostream>
#include "allegro5/allegro.h"

using namespace std;

int main(int argc, char **argv) {
    cout << "Hello, World!" << endl;

    al_init();
    return 0;
}

和CmakeList.txt：

cmake_minimum_required(VERSION 3.6)
project(untitled)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

set(SOURCE_FILES main.cpp)

LINK_DIRECTORIES(allegro/lib)
INCLUDE_DIRECTORIES(allegro/include)
add_executable(untitled ${SOURCE_FILES})

TARGET_LINK_LIBRARIES(untitled  allegro_acodec
        allegro_audio
        allegro_color
        allegro_dialog
        allegro_image
        allegro_main
        allegro_memfile
        allegro_physfs
        allegro_primitives
        allegro_ttf
        allegro_font
        allegro)


file(GLOB LIBRARIES "allegro/lib/*.dll.a")
message("LIBRARIES = ${LIBRARIES}")

TARGET_LINK_LIBRARIES(untitled  ${LIBRARIES})

这就是构建过程弹出的内容：

"C:\Program Files (x86)\JetBrains\CLion 2016.3.3\bin\cmake\bin\cmake.exe" --build C:\Users\Adrian\CLionProjects\untitled\cmake-build-debug --target untitled -- -j 8

我已经下载了Allegro 5 x64版本，从这里尝试了allegro-mingw-gcc5.3.0-x64-动态和静态：https://github.com/liballeg/allegro5/releases

谢谢

您必须使用与构建Allegro二进制文件相同的编译器版本。否则，它将无法正常工作。

将Allegro 5库与Jetbrains CLion一起使用
