[Mono-list] Fatal error when running a simple application under Mono
I am running a small, simple application using SVN release 128627 of Mono. This application used to work fine under earlier (ie pre 2.2) releases of Mono but has began to crash when using the newer version. When it runs I can interact with the widgets for a while and then it crashes with the below errors: [0x7fd27edb6720: 75.88669 15] LEAVE: INV_MainWindow:OnButtonExecuteClicked (object,System.EventArgs) [0x7fd27edb6720: 75.88670 14] LEAVE: (wrapper runtime-invoke) INV_MainWindow:runtime_invoke_void__this___object_object (object,intptr,intptr,intptr)[OBJECT:(nil)] [0x7fd27edb6720: 75.88671 13] LEAVE: (wrapper managed-to-native) System.Reflection.MonoMethod:InternalInvoke (object,object[],System.Exception&)[OBJECT:(nil)] [0x7fd27edb6720: 75.88673 12] LEAVE: System.Reflection.MonoMethod:Invoke (object,System.Reflection.BindingFlags,System.Reflection.Binder,object[],System.Globalization.CultureInfo)[OBJECT:(nil)] [0x7fd27edb6720: 75.88674 11] LEAVE: System.Reflection.MethodBase:Invoke (object,object[])[OBJECT:(nil)] [0x7fd27edb6720: 75.88675 10] LEAVE: System.Delegate:DynamicInvokeImpl (object[])[OBJECT:(nil)] [0x7fd27edb6720: 75.88675 9] LEAVE: System.MulticastDelegate:DynamicInvokeImpl (object[])[OBJECT:(nil)] [0x7fd27edb6720: 75.88676 8] LEAVE: System.Delegate:DynamicInvoke (object[])[OBJECT:(nil)] [0x7fd27edb6720: 75.88677 7] LEAVE: GLib.Signal:ClosureInvokedCB (object,GLib.ClosureInvokedArgs) [0x7fd27edb6720: 75.88678 6] LEAVE: GLib.SignalClosure:Invoke (GLib.ClosureInvokedArgs) [0x7fd27edb6720: 75.88679 5] LEAVE: GLib.SignalClosure:MarshalCallback (intptr,intptr,uint,intptr,intptr,intptr) [0x7fd27edb6720: 75.88680 4] LEAVE: (wrapper native-to-managed) GLib.SignalClosure:MarshalCallback (intptr,intptr,uint,intptr,intptr,intptr) Stacktrace: at (wrapper managed-to-native) Gtk.Application.gtk_main () <0x0006d> at (wrapper managed-to-native) Gtk.Application.gtk_main () <0x> at Gtk.Application.Run () <0x00027> at Investment_Returns.MainClass.Main (string[]) <0x00097> at (wrapper runtime-invoke) Investment_Returns.MainClass.runtime_invoke_void_object (object,intptr,intptr,intptr) <0x> Native stacktrace: mono [0x481506] mono [0x4b28dd] /lib/libpthread.so.0 [0x7fd27e0b6a80] Debug info from gdb: = Got a SIGSEGV while executing native code.

[Mono-list] Built GTK, GTK-SHARP and MONO from SVN - issue running MONO applications
Yesterday I fetched the latest versions of GTK and GTK-SHARP from SVN and built them. All seemed to go OK and files installed in various directories under /opt/mono. I keep GTK etc in here to keep in separate from my 'system' GTK. Today I fetched MONO from SVN and it also compiled fine. Again it went into /opt/mono so that I keep it separate from my system MONO. I am running Debian/Squeeze on a 64 bit machine and previous SVN builds have not caused me any problems. However, today when I try to run any mono applications they freeze and do not start up at all. When I ran mono --trace on one of them it goes OK until it hits the following: [0x7f2ea8f1c720: 3.49731 6] ENTER: (wrapper managed-to-native) Gtk.IconTheme:gtk_icon_theme_load_icon (intptr,intptr,int,int,intptr&)(0x1b05910, 0x1a0c2e0, 16, 0, [BYREF:0x7fffb0f38c18], ) which seemed to indicate an issue with either GTK or GTK-SHARP or MONO - so I have posted to both lists as I don't know which is more appropriate for the above problem. I am running version 22426 of GTK, version 128288 of GTK-SHARP and version 128288 of MONO . I do a make clean before each build and have also tried a make uninstall and then another make install to no avail. Any help would be much appreciated as I am unable to run my development environment MonoDevelop which depends on GTK, GTK-SHARP and MONO. Brett Senior.

My apologies for posting this twice but when I posted it the first time I was not subscribed to the Mono mailing list and thus has not been sent there and has been waiting to be moderated for a couple of days. So have re posted this one.

[Mono-list] Problem enumerating all mono processes on the system.
The following is some code that I have written to determine if the currently
running program is already running. The way that I tackled it was to search
for all mono processes and then within the process module collection to see if
any of them match the name of the program (minus the directory part of the
filename) then I increment a counter. If the counter is greater than one then
the program returns true, otherwise false.
Problem is that even if I have multiple instances of program 'xxx' running
using mono, only one mono process is returned. Within this process then only
one instance of 'xxx' is found in the process module collection. So the below
is unable to detect multiple instances of the program.
Can someone look at the below and point out what I am doing wrong ?
internal bool Is_Application_Already_Running()
{
int pc;
string pn1;
string pn2;
string [] cla;
System.Diagnostics.Process [] pra;
System.Diagnostics.ProcessModuleCollection pmc;
//
//Now using the command line (and its arguments), determine the
name of the .exe
//that was run.
//
cla = System.Environment.GetCommandLineArgs();
pn1 = cla[0];
pn2 =
pn1.Substring(pn1.LastIndexOf(System.IO.Path.DirectorySeparatorChar) + 1);
//
//Now obtain all processes that are running this program. Note: As
these programs are
//run under MONO, we must find all processes running this and then
determine via the
//name whether we should terminate them.
//
pc = 0;
pra = System.Diagnostics.Process.GetProcessesByName("mono");
//
//Now loop and kill each of the above processes - but not ourself.
//
for (int ix = 0; ix <= pra.GetUpperBound(0); ++ix)
{
//
//First obtain the modules associated with the process so we can
//then determine if it is running PN2.
//
pmc = pra[ix].Modules;
//
//Now loop and check the filename associated with the process
module
//and if we find a match then count up the number of instances.
//
for (int jx = 0; jx < pmc.Count; ++jx)
{
if (pmc[jx].FileName.EndsWith(pn2))
{
pc++;
}
}
}
//
//Now return true to indicate that the process is running elsewhere
if the
//process count is greater than one.
//
return (pc > 1);
}

[Mono-list] Failure to initialise ZLIB
I have an application written in MD/Mono and it uses GZipStream. The application runs fine for a while, performing file compression etc, but after about 10,000 files processed, I get the following error: Failed to initialize zlib. You probably have an old zlib installed. Version 1.2.0.4 or later is required. I have checked my zlib version and it is 1.2.3.3. To make sure things were OK I went into Synaptic (I run Debian/Lenny) and re-installed the libary. I recently downloaded the mono source and performed an update to what I'd had which was a version that came down via apt-get. Is the above an issue when processing large numbers of files using GZipStream - or is my application buggy in some way. Thank you, Brett Senior.
