How to run a command from a program while having only .rpm file ?

GoldenDracoa · 03-20-2016, 05:27 AM

Hi ! I don't really know where to post this

So, here is the context :
I'm coding a steganography program blablabla, and I want it to run under windows AND linux. The only problem is about Steghide (you can find it here : steghide.sourceforge.net ) I downloaded the windows AND the linux pack. So, when I call the function, I call the .exe version (of course). But, I don't know how I can call the steghide from the .rpm function

Do I have to install the package via my program ? Or is there a way to make it run easier ?

Thank for reading, I hope it was correctly said

waiting for your answer ! <3

Could you give us a little more information?
We can probably help more if we know which linux distro you are using.

rpm's are" RedHat Package Manager " compresed archives

somewhat like a zip or a rar or a Microsoft .msi

you install them on redhat based operating systems

also looking at that SF page
this thing is ANCIENT
the rpms are for suse 8 from 2003
they are 13 YEARS OLD

and will not run on modern operating systems

WHY do you need such a OLD and out of date program ?

petelg : Here my machine is a windows, but the program has to be able to run under debian linux (wheezy or jessie)

It's a Java program, here is the part of code concerned if you need to read it :

Code:

        System.out.println("Starting Extraction");
        File tmp = new File ("resources"+p+"embedMsg.txt");
        String[] cmd = new String[]{"","extract", "-sf resources"+p+"receiv.bmp", "-xf resources"+p+"extractMsg.txt", "-p "+passphrase};
        if (os.contains("Windows")) {
            System.out.println("Windows OS detected");
            cmd[0]="resources"+p+"steghide"+p+"steghide.exe";
        } else {
            System.out.println("Other OS detected");
            cmd[0] = "resources"+p+"steghide"+p+"./steghide"; //HERE i don't no what to write, so I wrote this. There is only the .rpm here
        }

John VV : I didn't know about this :s It's because it's the file I found, I thought I just had to use it... :s

If you're trying to run a rpm on debian you will have great difficulty anyway. But as JohnVV points out it's not been touched for 13 years so is not going to work even on an rpm system like Red Hat or openSUSE.

I'm not sure why you want a linux program for an MS Windows system though.

petelq :
Well, it's a project I have to do :P and, I'm coding on windows, but there is a risk that my teacher will test it on linux.. And, I can't execute steghide.exe in linux xD not automatically xP

Well, anyway, it there really is no way to use it, I will find a way to force him to help us >.<

Microsoft Windows *.exe files will NOT run on a linux Operating system
just like they will not run on Apples OSX mac's

you could build this ancient 13 year old source code
but with it being 13 years out of date , it is something i my self would NOT do because it will be a HUGE pain in the rear end
-- hemorrhoids pain ---

https://sourceforge.net/projects/ste...teghide/0.5.1/

the source
steghide-0.5.1.tar.gz

read the README file for the prerequisites like
libmhash
libmcrypt
libjpeg
zlib
but you are going to need the 13 year old VERSIONS of these programs
