品牌中未定义的参考 [英] Undefined reference in make

问题描述

我正在编译包含许多文件的代码，其中一些位于本地MATLAB安装文件夹中.为此，我在g ++中添加了一个include，显然它不能很好地解决，因为我得到了所有MATLAB-C ++函数的未定义引用(我正在尝试使用MATLAB C ++ Engine)，在以下屏幕截图中显示:

I'm compiling a code with many files and some are located in the local MATLAB installation folder. For this I've added an include to g++ which apparently doesn't resolve well because I get an undefined reference to for all MATLAB-C++ functions (I'm trying to use the MATLAB C++ Engine) as shown in the following screenshot:

Makefile非常短，因此:

The Makefile is very short and as such:

我已经检查了引用目录，它确实包含了 constraints.cpp 引用的"Engine.h"，通常足以执行MATLAB-C ++引擎功能.

I've checked the referenced directory and it does include the "Engine.h" referenced by constraints.cpp which is generally enough to execute the MATLAB-C++ engine functions.

关于此问题可能来自何处的任何想法?

推荐答案

您需要与MATLIB库文件链接.您的代码正在引用它们，但是链接器不知道它们是什么.

You need to link with the MATLIB library files. Your code is referencing them, but the linker doesn't know what they are.
