开发工具包；从 hostsample.cpp 构建 mex 文件时出错

Question

我正在编写一个 c++ 文件以构建到 mex 中，但是我使用 asio 函数遇到了未解决的外部符号错误，例如 "ASIOExit"。我正在使用 mex 命令在 Matlab 控制台中构建。 我已经从 AsioSDK 中放入了所有头文件和 cpp 文件。放入一个文件夹广告中 -I 包含该文件夹。我还需要包括什么或 link?

ASIO相关的3个头文件已经添加到include中了

#include "asiosys.h" 
#include "asio.h"
#include "asiodrivers.h"

Answer 1

好的，看来我没有在解决方案中包含所有 cpp 和 h 文件。
