[Monodevelop-devel] Running MD on .NET

[Michael Hutchinson]

I've tried running MD on .NET my combining the dependencies (MonoDoc
in particular was helpful) from Jonathan Pobst's MD zip with dlls
extracted from my trunk RPMs.

I've successfully run MD on .NET 3.5SP1 on XP32 and Vista64 without
any actual crashes, but a lot of things don't work.

There are a few caveats to getting it running:

a) On 64-bits, the MD binary has to be flagged as a 32-bit binary
using Corflags.exe
b) The WindowsPlatformService has to be build against the MD binaries
c) The path in the MonoDevelop.exe.addins has to be altered to  use \
directory separators.
d) Mono.Posix.dll 1.0 has to be installed to the GAC, because MD needs
both 2.0 and 1.0. 2.0 and PosixHelper (as per jpobsts' zip) can go
alongside MD.
e) The GnomePlatformService has to be removed

I've catalogued the errors I came across so far:


1) At startup, and when trying to load projects:

ERROR [2009-02-06 03:06:42Z]: Add-in error (MonoDevelop.Projects):

2) When closing MD, with no documents open. Prevents cleanly closing MD:

ERROR [2009-02-06 03:12:41Z]: Unhandled exception in GLib event handler.

3) Dragging pads around:

4) A message box warning of of an "Invalid path" when saving
preference of default path for new projects.


5) MD shows nonexistent language * if "New file" dialog when no .NET
language addins are present.


6) "Illegal Project Name" when creating a solution, presumably due to C:\ etc


7) GTK# error prevents opening the text editor:


System.AccessViolationException: Attempted to read or write protected
memory. This is often an indication that other memory is corrupt.   at

(I only have this on vista64/.net32 the editors open fine on my XP32 machine).


8) Addin error at startup:


ERROR [2009-02-06 03:30:26Z]: Add-in error (MonoDevelop.NUnit):

9) Failed GTK+ assertions in the open file dialog:

10) Tabs on bottom of docks are painted upside-down.


11) Theme changes of base colour propagate to the children of the
dacks, but not the base areas that the docks draw.


12) MD doesn't use native widget styles unless the windows theme is
changed while MD is running.


13) I don't have the traces right now, and I can't repro in vista64
because of (7) but the .NET VM was complaining about violated type
constraints in the history service. I wonder if gmcs is generating
invalid IL?


14) Also can't repro right now due to (7), but the text editor was
behaving very strangely, deleting random text, with some generics
errors about the Delete Action<T>.


15) At startup, an error scanning an unmanaged dll:
ERROR: There was an error while scanning assembly:
C:\Users\Michael\Desktop\MonoDevelop\bin\MonoPosixHelper.dll (The
module was expected to contain an assembly manifest. (Exception from
HRESULT: 0x80131018))


15) Querying the assembly code completion DB causes everything to fall
apart horribly (offset errors on pidbs, remoting failed to start,
MonoDoc panicking etc), so C# and ASP.NET completion are out of the
question right now. However, I did get HTML completion working despite
(14).


16) Addin error:
ERROR [2009-02-06 04:01:50Z]: Add-in error (MonoDevelop.NUnit):

17) Closing default policies window after changing settings:
