使用gcc和g ++分别用C和C ++文件编译项目？

标签： c++ c gcc makefile g++

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。

是否可以使用Makefile来“分离”C和C ++文件，C文件将使用gcc进行编译，使用g ++编译C ++文件并创建一个二进制文件？

这是我创建的Makefile：

这些是我执行make时收到的错误：

答案 0 :(得分：1)

尝试添加以下规则：

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

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

将主线更改为：

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

这是尝试将其集成到您的代码中。不过，我并没有这样做。
