Unable to run 'octave-cli' executable. Adding octave-cli path to the code.

[Eslam93]

Adding the bin folder to system path was working fine with me, but I need to use it through code for deployment purposes, but it won't work correctly with me, it always through an exception that I've added details below.

My usage goes like that

OctaveContext.OctaveSettings.OctaveCliPath = @"D:\InstalledPrograms\Octave\Octave-5.1.0.0\mingw64\bin\"; // add octave logic using (var octave = new OctaveContext()) { octave.Execute("pkg load image;");

I've tried to change the path several changes by adding the octave-cli file name with and without the .exe extension. i've copied the file into my project path, but failed in all nonetheless.

How to specify path to octave-cli binary in my code? I'm using .Net framework 4.7 and 4.6.1 in my project.

Thank you so much.

It expects the full path of octave-cli.exe.

Thank you @triforcely . but I've tried both OctaveContext.OctaveSettings.OctaveCliPath = @"D:\InstalledPrograms\Octave\Octave-5.1.0.0\mingw64\bin\octave-cli.exe" and OctaveContext.OctaveSettings.OctaveCliPath = @"D:\InstalledPrograms\Octave\Octave-5.1.0.0\mingw64\bin\octave-cli"

and it didn't work with me either ways. did I miss something?

[triforcely]

You should have similar exception message when the binary is missing. Your message only contains "octave-cli", are you sure you sent the correct error message?

[Eslam93]

Yes I'm sure, it always only gives me 'octave-cli', even if in octave object I find the path in the setting I've typed

I'm going to need repo with a reproducible example to look into this issue.

[Eslam93]

Ok thank you so much, I'll be doing that now, but I've noticed that our octave versions are different and having a different bin path inside octave, would that be the issue may be?

[triforcely]

Just tested with newest version and it works fine. But the inner exception explicitly says, that the system cannot find the file specified so it doesn't even come to the point where it runs Octave.

Finally, Thank you again @triforcely , the issue was on my side, but was a bit more about my architecture of the project not how the string is written, I figured it out while recreating the project for the online rep. my solution that I had to create a constructor that set the OctaveCliPath there, as setting it inside the function didn't apply the change for some reason.

Thank you again man.

I'm happy to hear that it works :)
