我需要在 C 程序中从 C++ 程序中调用一些方法。

但我只有一个共享库 ( .dll) 来使用这些方法。

为此，首先在 C 中创建一个包装器，以调用dll要在 C 程序中使用的方法。我有注意，我确保我声明函数extern "C"以避免名称修改。

但是当编译时我有一组错误（如下所示），当链接墙时.o：

g++ -o bonnie++ bonnie++.o bon_io.o bon_file.o bon_time.o semaphore.o sync.o thread.o bon_suid.o duration.o rand.o util.o utils.o super.o pcm_file.o inode.o iname.o dir.o pcm.o -lpthread -L./ -lSmart

有人知道我做错了什么吗？

您是否在包装方法源文件中包含外部“C”函数声明头文件？如果没有，就会出现这个错误
