[Mono-dev] gtksourceview: compilation error and strange runtime behaviour/errors

[Quandary]

Hi,

I'm now trying to get SQL Syntax highlighting to work with GTK.
And I already had 2  problems just getting the gtksourceview sample to
work...

Problem 1 (file: gtksourceview/generated/SourcePrintJob.cs):
[Obsolete]
protected SourcePrintJob(GLib.GType gtype) : base(gtype) {}

This gives a compilation error, because this constructor still is used
(in the sample, I guess)...
Now obsolete or not, as long as it still is used, this has to be:
public SourcePrintJob(GLib.GType gtype) : base(gtype) {}

or else:

Problem 2:
Does the example use the 2.0 version of gtksourceview-sharp ?
Without looking into the makefile: it doesn't seem that way.

********
root at IS1300-1:/etc/ld.so.conf.d# cat gtksource*

# mono needs you
/usr/local/lib/mono/gtksourceview-sharp-2.0

# mono needs you
/usr/local/lib/mono/gac/gtksourceview-sharp

# mono needs you
/usr/local/lib/mono/gac/gtksourceview-sharp/1.0.0.2__35e10195dab3c99f

root at IS1300-1:/etc/ld.so.conf.d# /sbin/ldconfig
********

And it still doesn't find the dll.
Furthermore, if I copy
/usr/local/lib/mono/gac/gtksourceview-sharp/1.0.0.2__35e10195dab3c99f/1gtksourceview-sharp.dll
into the sample directory, it starts working.

This is strange, because this should have started working the moment the
directory was included in /etc/ld.so.conf.d/ and /sbin/ldconfig was run.
Besides, the dll always was in the gac...

It seems to require localcopy, even if the dll is in the gac and/or in
the ld-paths.


My interpretation is that:
A) The sample is compiled referencing an old version of gtksourceview

B) Mono seems to ignore ldconfig settings, at least for non-native dll's.

and since it looks like it doesn't consider
/usr/local/lib/mono/gac.
but only
/usr/lib/mono/gac

C) that either the install directory or the lookup of it is wrong.

and

D) that it (=mono/ld-linux) gladly ignores export
LD_PRELOAD="/usr/local/lib/mono/gac/gtksourceview-sharp/1.0.0.2__35e10195dab3c99f/1gtksourceview-sharp.dll"
