[Mono-list] PDF Creaation Library for Mono

2004-10-17 Thread mono-list . 1 . tracyanne 
What I would like to know is how did you get iTextSharp to compile under
Mono. I've used it and compiled it successfully under .NET, but never
Mono.

When I attempt to compile it under Mono (Mono 1.0.2) I get the following
error messafges


[Task:File=/home/tracy/Mono/iTS4/iTextSharp/text/rtf/RtfRow.cs,
Line=222, Column=-1, Type=Error, Description=Expecting `;'(CS1002)

But I am unable to find anything wrong with the code.

it compiled with mono without any problems - seems to be quite feature

What about listing the complete directory and growing an Hashtable with
keys="lowercase name" and value="original name" ?  I think samba and
wine do something similar.

The default mode has to be case sensitive, but a --case-insensistive
mode for mono would probably be useful to run uncareful closed-source
assemblies.

Re: [Mono-list] Cross platform app on usb drive

2004-10-17 Thread Dmitry Kostenko 

I have tried something similar, but on Windows only. It worked.
For quick testing you can make use of SUBST'ed drives in Windows.
e.g. You create a drive as
> mkdir D:\env1
> subst S: D:\env
and install Mono onto it.
Now you can 'hide' installed mono by 
> Subst S: /D

Let's pretend you make a distribution onto drive Z:
You clean drive Z:
Install mono into Z:\mono
Fix the .BAT files and remove all references to Z: from them.
Now mono works on Z: only by starting \Mono\mono
Copy you application into Z:\YourApp
Put .bat file into root:
@cd \YouApp
@\mono\mono YouApp.exe

To test whether installation is drive-independent (on Windows) you can
use different substed drive letters.

Under Linux it should be easy too: 
Let's pretend, that your mountpoint it /mnt/flash (which is the same as
Z:\ under Windows).
Package mono-linux into /mnt/flash/mono-linux.
Put startup .sh script into /mnt/flash 
#!/bin/sh

# WD is rooted path to working directory/mount point
WD=`basename $0`
if [ -z "$WD" ] ; then WD=`which $0`; fi
if [ "$WD" = "./" ]; then WD=$PWD; fi

export LD_LIBRARY_PATH=$WD/mono-linux/lib
export MONO_PATH=$WD/mono-linux/lib:$WD/mono-linux/lib/mono/1.0:
$WD/mono-linux/lib/mono/gtk-sharp

$WD/mono-linux/bin/mono $WD/YourApp/YourApp.exe $*

Most probably you use Gtk+ 2.4 or newer under Linux (You should have with 
Glade 2.6.x).
And AFAIK Gtk# officially supports (and is distributed with) Gtk+ 2.2, which 
does not support those classes or properties.

Most probably you have declared a Gtk.ToolButton widget in your window, and 
you reference it in the code. And since Gtk+ 2.2 does not have such class, 
your widget pointer is initialized with null, and that's why you receive the 
exception.

Either use Glade compatible with Gtk+ 2.2 (I use Glade 1.1.3). Or get Gtk+ 2.4 
binaries from sf.net (see http://sf.net/projects/gaim ;) ).

I will try to dig up the tests or to recreate them.

You are probably correct that this is not a very large problem in practice. As 
I recall, I had to make the number of iterations quite large to see a 
substantial difference in time.

On the other hand, I did this test because I have a program that needs to 
perform a large number of three-way decisions like this.

Have you instaled devel libraries of glib-dev? (I don't know what is the
exactly name). Devel libraries of packages have the .pc files you need
for compile some gtk-sharp programs. If you have installed the libraries
and the problem continues, you can try to set the PKG_CONFIG_PATH
variable with the directory pkgconfig where are .pc files.

echo $PKG_CONFIG_PATH
/usr/local/lib/pkgconfig/:/lib/pkgconfig

Good Luck!

In the case of .NET it has to be installed in the machine.

With Mono it is possible to run from the drive.

It's also cpu-dependent: some processors may not do branch prediction
with indirect branches generated by a switch, but they do it with
conditional branches generated with if/else.
We may add the code to turn a switch with less than 3-4 destinations
to a if/else sequence, but I'm not sure if this is really a speed 
problem in practice. Marcus reported behaviour may be due to different IL code 
generated by the compiler: I'd like to see the actual IL code
to determine what actually caused the performance issue he reported.

blargh, sorry, not thinking straight. What I meant was 1 + 1/3 = 1. I
believe I was right on the big-picture stuff, I just stuffed up a number
in the example.

Sorry,

However, when you have switch in the CIL, it's up to the JIT how to handle
it. And choosing between the if-else and the jump-table implementation
can be machine dependent, performance wise.

According to the spec -- it's not. You simply cannot have tailcall if
any ldloca/ldarga are involved. Since then you would have to pass
managed pointer to the called function, which is not permitted in the
verifiable CIL. So the ,,rationale'' for the tail prefix listed there
seems bogus.

ld{loc,arg}a loads address of a value in the current stack frame.
Which you're going to destroy with the tail call.
