Re: [Mono-dev] Mono on DD-WRT or OpenWrt
Hi, Rodrigo Kumpera wrote: Well, OpenWrt runs mostly or arm based devises, so mono should work. The issue will be building a small enough runtime to fit the flash card. Sorry not mentioning the architecture. The devices I'm interested in use the MIPS32 architecture. I've found few documentation on the status of MIPS support on the home page. The disk space problem can be solved by using an external hard drive connected via USB. (Other solutions involve hardware modification.)

Re: [Mono-dev] System.Drawing.Graphics ignores InterpolationMode
Hello, Cairo, on which libgdiplus depends for graphics, has much less interpolation options than MS GDI+ defines in its API. So libgdiplus maps many to few options in this case. Cairo is also known not to downscale images very well (but some Cairo people are looking at this). Google cairo's mailing-list if you want to know more about the issues.

[Mono-dev] SEGV in mono_class_is_assignable_from in gmcs
I'm getting a SEGV in the function `mono_class_is_assignable_from' when
trying to compile some internal code. I can't get the location in my
source code where the error occurs, but I'll add some info from GDB to
this email. Has anyone seen something like this before?
This is with a mono/gmcs from the mono-2-0 branch, revision 110293. I
*think* the class being compiled is of the form class FooT :
IComparableFooT, but I've been unsuccessful in getting a simple
test case so far.

Running gmcs under the mono debugger got me further: I was able to find the code causing the issue. There were two methods in a class that had the form: private static XXXT FindRelevantT(XXXT[] candidates); private static object FindRelevantT(IComparable[] candidates); And the type XXX is 'public class XXXT : IComparableXXXT'. These FindRelevant methods are called in various places in the containing class, always with an argument of type XXXT[].
