I asked something similar a while back. I've pasted the contents of that discussion below. Max --- begin pasted discussion --- On 13.12.2010, at 09:54, Stéphane Ducasse wrote:

Guys

we should create a nice documentation for the OSProcess please please spend some time on the collabactive book because we need more documentation.

OSProcess, which I am learning to like more as I learn more about it, is not well supported on Windows. Dave recently advised me to use ProcessWrapper on Windows; if he is saying that, then it must be the better path for now.

I have done FFI on both Windows and Linux. I have not (yet anyway) done any one task in a cross-platform way. So far, I have not seen anything horrible that would prevent it. I have zero interest (at least so far) in moving my numerical analysis adventures back toward Windows (they started there and moved to Linux where I am quite happy). I have a .so interface to Acces IO A/D hardware and a DLL interface to Ascension Technology's 3D tracking software. Ultimately, I hope to be able to use both of them on either platform (the software exists on both), but have not yet made the connections.

I transparently use OutputDebugString() on Linux and syslog() on Linux, but that does a test on platform and calls completely different code, so it does not count here.

Sorry I can't be of more help. I urge you to wade into it and ask for help as you get stuck. For creating libraries, you might want to have a look at Code::Blocks; I don't push it very hard, but I have no complaints. The "default" is to install MinGW on Windows (last time I looked at least) and it uses gcc on Linux.

With OS Process you can run scripts. That should work identical on Mac and Unix systems; probably also Windows, but I haven't tried.

With FFI and Alien you can call C libraries. I have not much experience with those, but normally it should be possible to use them on all platforms.

Hi guys

I was wondering if it is true that executing a file from within Pharo is platform dependent. I don't actually need to execute a file; it's more a theoretical question and I have no idea what the mechanisms are that would be used. To give you a clearer picture: Imagine you have C, sh, and perl files. What I'm thinking about is that I would have some data in the image that I would want to process with the code in one of those files. I would then wait for the result and process the result in the image.

So my questions are: is there a platform independent way to execute C, sh or perl files from Pharo? Does the VM handle the platform dependencies? Are there any other issues with the idea I described?

Don't go out of your way to find answers, please. But I'd be happy to hear your thoughts.

Cheers, Max

I think you will find that OS Process work on mac an Linux and NOT on Windows, but ProcessWrapper does work there. A test on the OS should let you interchange them well enough to get by.

What is the best option?

I need call executable files of OS. I see various options, but I´m not sure. I believe don´t understand correctly.

I need:

-Call executable files from system. -Call associated programs of links, for example, I could pass 'http://google.com'. The result must be open the default browser of user with that link. -Call commands or .BATs files from OS. -I need use that on any OS, must be cross-platform, is very important.

If that is not implemented on Pharo, is possible create a .exe file with another language, where I call functions of OS, and invoke from Smalltalk that exe?

Regards.
