链接器没有检测到我为 raylib 制作的静态库

问：

我目前正在尝试创建一个小型库来在 raylib 中制作对话框。但是，当我尝试使用我的 Makefile 时，我收到此错误。请注意，我对 c++ 有点陌生！

/sbin/ld: cannot find -ldialog: No such file or directory
collect2: error: ld returned 1 exit status
make: *** [Makefile:14: test] Error 1

这是我的其余代码，因为我不确定是什么原因导致的，因为头文件和库文件分别位于 /usr/include 和 /usr/lib 中。

对话框.cpp -

#include <cstring>
#include <string>
#include <raylib.h>

using namespace std;

class DialogueBox {
    public:
    float thickness;
    Color box_background;
    char *contents;
    bool shadow;
    Rectangle rectangle;

    DialogueBox(float x, float y, float width, float height) {
        Rectangle rectangle = {x,y,width,height};
        contents = "Hello!";
    }

    void Draw(){
        if(shadow){
            DrawRectangle(rectangle.x + 10,rectangle.y + 10,rectangle.width,rectangle.height,GRAY);
        }
        DrawRectangleRec(rectangle, box_background);
        DrawRectangleLinesEx(rectangle, thickness, BLACK);

        for(int i = 0; i < strlen(contents); i++){
            char charBuffer[2] = {contents[i], '\0'};
            DrawText(std::string(1, contents[i]).c_str(), rectangle.x, rectangle.y, 5, BLACK);
        }
    }
};

dialog.h：

#ifndef DIALOGUE_BOX_H
#define DIALOGUE_BOX_H

#include <cstring>
#include <string>
#include <raylib.h>

class DialogueBox {
public:
    DialogueBox(float x, float y, float width, float height);

    void Draw();
    float thickness;
    Color box_background;
    char *contents;
    bool shadow;
    Rectangle rectangle;
};

#endif // DIALOGUE_BOX_H

测试.cpp：

#include "dialog.h"
#include "raylib.h"

int main(void)
{
    const int screenWidth = 800;
    const int screenHeight = 450;

    InitWindow(screenWidth, screenHeight, "raylib [core] example - basic window");

    SetTargetFPS(60);

    DialogueBox dialog(5, screenHeight/4, screenHeight/4 + screenHeight/4, screenWidth - 5);
    dialog.thickness = 5;
    dialog.box_background = GRAY;
    dialog.shadow = true;

    while (!WindowShouldClose())
    {
        BeginDrawing();

            ClearBackground(RAYWHITE);
            dialog.Draw();

        EndDrawing();
    }

    CloseWindow();

    return 0;
}

生成文件：

CC = gcc
CFLAGS = -O1
LIBS = -lraylib -lGL -lm -lpthread -ldl -lrt -lX11

all: dialog.o libdialog.a install test

dialog.o: dialog.cpp
    $(CC) $(CFLAGS) -c dialog.cpp -o dialog.o $(LIBS)

libdialog.a: dialog.o
    ar rcs libdialog.a dialog.o
    rm dialog.o
test: test.cpp
    $(CC) $(CFLAGS) test.cpp -o test $(LIBS) -ldialog

clean:
    rm /usr/bin/libdialog.a
    rm /usr/include/dialog.h
    rm libdialog.a
install: libdialog.a dialog.h
    cp libdialog.a /usr/bin
    cp dialog.h /usr/include

先谢谢你！
