使用任意PATH环境安装MathLink程序 [英] Install MathLink program with arbitrary PATH environment

问题描述

可以使用安装[] 启动具有自定义 PATH 环境变量的MathLink程序

Is it possible to use Install[] to start a MathLink program with a custom PATH environment variable?

我正在尝试使用 mEngine 将Mathematica连接到Windows上的MATLAB。只有当 PATH 环境变量包含MATLAB库的路径时，才会启动 mEngine.exe 。是否可以修改PATH以启动此程序 ，而不需要修改系统路径？或者有另一种方法来启动 mEngine.exe ？

I am trying to use mEngine to connect Mathematica to MATLAB on Windows. It only works if mEngine.exe is launched when the PATH environment variable includes the path to the MATLAB libraries. Is it possible to modify the PATH for launching this program only, without needing to modify the system path? Or is there another way to launch mEngine.exe?

推荐答案

acl的解决方案将mEngine.exe包装在一个批处理文件中，并临时修改PATH，可以正常工作：

@acl's solution to wrap mEngine.exe in a batch file, and temporarily modify the PATH from there, works correctly:

我将其用作 mEngine.bat ：

set PATH=c:\path\to\matlab\bin\win32;%PATH%
start mEngine.exe %*

• *％确保所有命令行参数传递到 mEngine.exe


• 开始是必要的，以防止命令窗口保持打开，直到 mEngine.exe 终止


• *% ensures that all command line arguments are passed on to mEngine.exe
• start is necessary to prevent the command window from staying open until mEngine.exe terminates

可以使用安装[mEngine.bat] 开始。

由于内核与 mEngine.exe 通信所需的所有信息都通过安装[] 作为命令行参数，我们需要做的只是la unch mEngine.exe 带有这些参数。 安装[] 不需要知道 mEngine.exe 的位置，重要的是进程使用正确的命令行参数启动，由％* 确保。

Since all the information that is needed for the kernel to communicate with mEngine.exe is passed by Install[] as command line arguments, all we need to do is launch mEngine.exe with these arguments. It is not necessary for Install[] to know the location of mEngine.exe, the important thing is that the process gets launched with the correct command line arguments, which is ensured by %*.
