连接到Matlab引擎从C在Linux中 [英] Connect to Matlab engine from C in Linux

问题描述

我试图在Linux（Matlab的r2009a，Ubuntu 9.10的）一​​个C程序编程调用Matlab引擎。

I'm trying to call the Matlab engine programatically from a C program on Linux (Matlab r2009a, Ubuntu 9.10).

我有我自己的code（这在Windows工作），但现在我只是试图让Matlab的engdemo.c计划在Linux上运行。我已成功地编译和放大器;其链接（包括大约15后 -l＆LT; LIB＆GT; 切换GCC命令行），甚至解决了所有通过某些ldconfig的魔法运行时动态链接

I've got my own code (which works in Windows), but for now I'm just trying to get the Matlab "engdemo.c" program to work on Linux. I have managed to compile & link it (after including about 15 -l<lib> switches on the gcc command line), and even resolved all the runtime dynamic links via some ldconfig magic.

不过，当程序运行时，我刚刚得到的无法启动Matlab引擎的错误消息，并且程序结束，没有指示失败的原因。

But, when the program runs, I just get the "Can't start MATLAB engine" error message and the program ends, with no indication of why it failed.

有没有人做这项工作？我有什么忘了怎么办？

Has anybody made this work? What have I forgotten to do?

P.S。我本来问这个超级用户，因为我认为这是配置相关的，但我看到其他Matlab引擎相关的？是在这里，所以我想我给它一个去。

p.s. I originally asked this on SuperUser because I think it's configuration related, but I see other Matlab engine-related ?'s here so I thought I'd give it a go.

推荐答案

您应该在你的C程序运行 strace的，看看那里出问题。通常情况下，我发现大部分归结为时间之一：

You should run strace on your C program to see where things go wrong. Typically, I found that most of the time it comes down to either:

• 不具有 CSH 安装


• 具有环境设置错误，有时 LS_COLORS 螺丝钉的事了 CSH

• Not having csh installed
• Having the environment set wrong, sometimes LS_COLORS screws things up with csh
