## Re: Yet another thread on Octave on Windows.

 From: Ole Jacob Hagen Subject: Re: Yet another thread on Octave on Windows. Date: Fri, 14 Jan 2005 13:17:05 +0100 User-agent: Mozilla Thunderbird 1.0 (Windows/20041206)

```Hi, Paul.

When I start Octave like this:
```
octave --interactive --path D:\\Octave\\OctaveBin\\share\\octave\\2.1.64\\m --exec-path D:\\Octave\\OctaveBin\\libexec\\octave
```
```
Then finds the oct and m-files in these folders. But it doesn't search recursively, how can I accomplish this?
```That would be nice, so I don't have to copy ALL m-files into one directory.

```
I've recently found a readline for Win32. I will check this package shortly. ;)
```

Cheers,

Ole J.

By the way, here is a benchmark test of Octave-2.1.64 compiled with MinGW (gcc-3.2.3) on Windows XP.
```This Octave works natively on Windows.

Are these timings good enough?
