Like I've already said in this thread, using a process to run uname is
senseless overhead. Use p/invoke like in XplatUI.cs

Re: [Mono-list] Detecting if platform is Mac
argg, sorry chris , i would like to send this to the list :
declare a "string Platform = "win";"
use :
if(environment.platformid == unix) to use a process with redirect
output and start
process.start("uname -a");
then parse the response with .indexof

My favorite method of dealing with platform-specific native libraries is to find a function in the libraries that doesn't do anything, or that you can feed invalid input to cause it to do nothing (but obviously not crash). Specify a P/Invoke definition for each, then call them until you find one that doesn't throw DllNotFoundException. Then that's your library/platform. -- Chris Howie http://www.chrishowie.com http://en.wikipedia.org/wiki/User:Crazycomputers ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
Re: [Mono-list] Detecting if platform is Mac
So, the reason I want to detect if we are running MacOS is I am writing Mac OpenGL bindings for the OpenTK project. On MacOS we need to make appropriate AGL calls instead of GLX or WGL calls in order to construct an OpenGL context. Perhaps a better solution would be to check the type of the XPlatUI driver to see what it is, although I'd like to avoid writing code which depends on private mono internals.

Of course, I don't care about the Xbox value I am just > interested in being able to detect whether my code is running on MacOS > or Linux. We added support for reporting this value back, but it turned out to break too much code in both Mono and our own modules, so we took this patch out. A lot of code assumed that it was Unix if the value was Unix, and when we returned the new value assumed it was running on Windows. We will continue to monitor progress on third party code and eventually make this change. But in general, the PlatformID is a poor way of detecting the platform, and instead you should base your code on other parameters like path separators for example. ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list

This works, but I don't know if there's a better way. Dont spawn uname, p/invoke it.

[Mono-list] Detecting if platform is Mac
Apparently in .NET 3.5 Microsoft added two members to the System.PlatformID type, called Xbox and MacOSX. Is there any support in Mono for these? Of course, I don't care about the Xbox value I am just interested in being able to detect whether my code is running on MacOS or Linux. Otherwise, is there another recommended way to detect if running on MacOS? Currently we are spawning uname and checking to see if the output is "Darwin". This works, but I don't know if there's a better way. ___ Mono-list maillist - Mono-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list
