在dll${pathToDir}\demoGame.exe中找不到过程入口点_ZdlPvj 我试图建立SDL2来创建一个Windows的C++游戏。当我只使用一个源文件运行下面的make文件时，不会出现错误，程序也可以运行。当我尝试使用多个源文件运行make文件时，编译会顺利进行，但当我尝试运行程序时，会出现标题中显示的错误。只有在尝试在第二个源文件中创建类的实例，并尝试访问成员或实例函数时，才会出现这种情况

我已经尝试过重新下载和设置我的环境，更新mingw（尝试没有什么坏处），并对我的代码进行三重检查。我已经包括了makefile，以及我正在使用的源文件。谢谢你的帮助

编辑：似乎是主函数中的删除调用导致了此错误。。。不确定这是巧合还是原因就在那里

#OBJS specifies which files to compile as part of the project
OBJS = src/*.cpp src/*.hpp

#CC specifies which compiler we're using
CC = g++

#INCLUDE_PATHS specifies the additional include paths we'll need
INCLUDE_PATHS = -Iinclude/SDL2

#LIBRARY_PATHS specifies the additional library paths we'll need
LIBRARY_PATHS = -Llib

#COMPILER_FLAGS specifies the additional compilation options we're using
# -w suppresses all warnings
# -Wl,-subsystem,windows gets rid of the console window
COMPILER_FLAGS = 

#LINKER_FLAGS specifies the libraries we're linking against
LINKER_FLAGS = -lmingw32 -lSDL2main -lSDL2

#OBJ_NAME specifies the name of our exectuable
OBJ_NAME = demoGame

#This is the target that compiles our executable

我认为这是因为游戏从

路径中的一些随机位置拾取了它所依赖的
.dll的错误版本。将
SDL2.dll
复制到
.exe
所在的目录。此外，从编译器的
/bin
目录中，复制
libgcc_s_seh-1.dll
，
libstdc++-6.dll
，
libwinpthread-1.dll
（名称可能略有不同，取决于您的MinGW发行版）。@HolyBlackCat非常感谢您，似乎已经修复了它！！：）
