从C调用Octave解释器-问题编译和运行示例

问题描述

按照此答案Call GNU Octave functions in C?所示的示例，我正在尝试从C实现调用八度。

我正在Linux上的Nebeans中尝试此操作。

根据示例，我已经创建了文件calloctave.cc，calloctave.h，main.c和myfunction.m。指向链接并包括到正确的位置（在我的情况下为/usr/include/octave-5.2.0/octave/和/usr/lib64/octave/5.2.0）。我选择了C ++ 11作为标准。在代码中，没有突出显示任何错误，并且似乎可以找到所需的所有内容，并且没有任何内容突出显示为丢失。

当我尝试对其进行编译时，只会出现如下一系列错误...。

似乎没有以某种方式理解mex界面。我对C / C ++不太了解，所以对如何进行此处很困惑。是什么原因导致这些错误，我该如何解决？
