[Mono-dev] How to use cross compiler arm-linux-gcc to build mono for ARM?
Hi, I've build my own board using Samsung S3C2410 ARM9 CPU, and it can run Linux 2.6.14 now. I have only the cross-compiler arm-linux-gcc that running in i386, and I found there is someone has ported mono to Nokia 770, I want to know How to use cross compiler arm-linux-gcc to build mono for ARM?

[Mono-dev] gtkSharpNotification and PKG_CONFIG_PATH help
This is my first posting to the list, so hello, and hope I'm not out of line with anything. I'm in the midst of putting together an OSX/Win application and am new to Mono/Gtk/Cocoa development (although not new to c/++/# or windows development). I'm receiving the following error when trying to run mono TrayTest.exe from the following source (after downloading both and compiling). http://www.mono-project.com/GtkSharpNotificationIcon unhandled exception : system.dllnotfoundexception:gdk-x11-2.0 in Egg.TrayIcon:gdk_x11_display_get_display 1) I have mono version 1.1.14 installed. 2) I'm using cygwin, have all -devel packages installed and can see gdk-x11-2.0.pc in /lib/pkgconfig. 3) PKG_CONFIG_PATH is set and looks like this : /usr/X11R6/lib/pkgconfig:/lib/pkgconfig:/bin/Mono-1.1.14/lib/pkgconfig (mono is installed in c:/cygwin/bin) 4) If I run pkg-config --libs gdk-x11-2.0, I get "Package gdk-x11-2.0 was not found in the pkg-config search path." 5) I turned on PKG_CONFIG_DEBUG_SPEW, and I get the following as a dump : "Cannot open directory '/usr/X11R6/lib/pkgconfig:/lib/pkgconfig:/bin/Mono-1.1.14/lib/pkgconfig' in package search path: No such file or directory. I've scoured the web and read through the blogs of the authors and the only thing I've found is to have the correct libraries installed. I found a few things in gnome to install both the gtk+ devel and glib -devel libraries, but I have (I believe), all the .pc files installed (from the error messages it just looks like pkg-config isn't looking in the right spot). Or if anyone has another idea as to how to get a notification area up and running on win/osX, I'd be much obliged. Any help or advice would be greatly appreciated. Thanks! ...Dave ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

[Mono-dev] remoting after ip change
I have problem that when I change the IP of the system doing remoting to itself some parts of remoting fail. The error I get is at the bottom. What is really strange is that part of the remoting works, as far as I can tell I can retrieve the remoting object using Activator.GetObject and I can make a method call which returns an array of Marshalbyref objects. The error doesn't happen until I start looping those Objects and printing out values from them. If I kill the code and run it again then it works just fine, this only happens when the IP changes while the code is running. Any ideas?

Safe and unsafe are used for different meanings between languages (e.g. C#) and the framework base class library. In this case, like many times it's used in the FX BCL, the Unsafe prefix means that special security requirements for this method makes it dangerous to use with non fully-trusted code (see MSDN documentation for more details). So unless you are using "mono --security" to activate the (partial and unsupported) security manager this *doesn't* affect you at all (as all your code is *always* executed under FullTrust). -- Sebastien Pouliot <[EMAIL PROTECTED]> Blog: http://pages.infinit.net/ctech/ ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list
Re: [Mono-dev] "safe" way about Marshal.UnsafeAddrOfPinnedArrayElement
Hi,
Unsafe code usually means code that uses pointers. But that unsafe code has
to use the fixed statement when accessing objects that can be moved. fixed
statement pins the object so that GC will not move it within the block of
fixed statement. (As far as I know Mono still uses non-moving GC but that
will change in the future and MS.NET uses moving GC.)
Marshal.UnsafeAddrOfPinnedArrayElement is unsafe in addition to pointer
operations because it assumes that the array is already pinned so it won't
(an in fact can't as it has no scope) pin the object so the GC can move it
that can result in invalidation of the returned pointer so has to be used
carefully. (When the array is moved by the GC you can overwrite some other
object that can have unpredictable results.)
Marshal.UnsafeAddrOfPinnedArrayElement is intended to be used with a pinned
GCHandle. (Or alternatively on an array that is already pinned using fixed
statement but in that case you have a pointer to an array element so you
probably don't need this method.)
If you have a non-pinned array you should use fixed statement instead as
Jonathan explained it.
So Marshal.UnsafeAddrOfPinnedArrayElement is even more unsafe than unsafe
code when used on a non-pinned array.

It's "unsafe" because you need to be careful. :-)
An alternative is to use *real* unsafe code, e.g.
FooStruct[] array = ...;
unsafe {
fixed (FooStruct* pArray = array) {
FooStruct* element = &pArray [index];
}
}
I'm not entirely sure what your problem is though. "Unsafe" code (like
the above `unsafe' block) just means that you're possibly executing
without a net, which could result in memory corruption and abortion of
the process. :-)
Marshal.UnsafeAddrOfPinnedArrayElement isn't even in an unsafe C#
context, it just has "Unsafe" in the name.
Here's a hint of truth: ANY time you do a P/Invoke, you're potentially
doing something unsafe. :-)
(Especially considering that you're invoking external code which could
really do anything, such as overwrite the entire GC heap, which would
cause the process an ugly death in the future...)
However, I'm not sure why you need
Marshal.UnsafeAddrOfPinnedArrayElement in the first place.
epoll_wait(2) takes a `struct epoll_event' array parameter, so unless
you wanted to only send a subset of your array, the default marshaling
rules which convert a managed array to an array pointer should be fine.

What usually happens is that when a rebuild is requested, not all of the other packages which depend on the rebuilt one are rebuilt. The reasons can be many fold. Normal users (those using core) don't see this very often, but it's something those using the developer branch (rawhide) have to put up with a lot.

It's normal to have problems like these ones when using the latest versions of packages, because unstability increases. In my humble and personal opinion, if you are very interested in the Mono platform and like to try the latest releases of the Mono tools, try the SUSE distribution because it's the closest to this software. Since I use SUSE I don't have any problems with package dependencies or stability of the latest versions of the Mono packages.
