c++ - 使用 gcc 和 g++ 分别编译包含 C 和 C++ 文件的项目？

Question

我有一个包含 C 和 C++ 文件的项目，我创建了一个 Makefile 来编译这个项目。

是否可以有一个 Makefile 来“分离”C 和 C++ 文件，C 文件将用 gcc 编译，C++ 文件用 g++ 编译并创建一个二进制文件？

这是我创建的 Makefile:

这些是我在执行 make 时收到的错误:

Answer 1

尝试添加这些规则:

%.o: %.c
     $(CC) $(CFLAGS) $<

%.o: %.cpp
     $(CPP) $(CFLAGS) $<

并将您的主线更改为:

$(NAME): $(OBJ) $(OBJCPP)
     $(LD)  $^ -o $@ $(LDFLAGS)

这是将其集成到您的代码中的尝试。不过，我没有运行它。
