* A debugging session using a symbol file which has been created by MCS.
Let's assume we have the following C# application which we want to debug:
<pre>
using System;
public class Foo
{
public struct MyStruct {
int a;
long b;
double c;
}
public static void Main ()
{
Int32 value = 5;
long test = 512;
MyStruct my_struct;
my_struct.a = 5;
my_struct.b = test;
my_struct.c = 23323.5235;
}
}
</pre>
First of all, we need to compile it with MCS, assemble the generated .s file and
create the .il files for all referenced assemblies which were not compiled with MCS:
<pre>
$ mcs -g ./Foo.cs
$ as -o Foo-debug.o Foo-debug.s
$ monodis /home/export/martin/MONO-LINUX/lib/corlib.dll > corlib.il
</pre>
Now we can start the JIT in the debugger:
<pre>
$ gdb ~/monocvs/mono/mono/jit/mono
(gdb) r --dwarf-plus --debug Foo:Main ./Foo.exe
Starting program: /home/martin/monocvs/mono/mono/jit/mono --dwarf-plus --debug Foo:Main ./Foo.exe
Program received signal SIGTRAP, Trace/breakpoint trap.
0x081e8681 in ?? ()
(gdb) call mono_debug_make_symbols ()
(gdb) add-symbol-file Foo-debug.o
(gdb) add-symbol-file /tmp/corlib.o
` (gdb) frame
#0 Main () at ./Foo.cs:11
11 public static void Main ()
(gdb) n
Main () at ./Foo.cs:13
13 Int32 value = 5;
(gdb)
14 long test = 512;
(gdb)
17 my_struct.a = 5;
(gdb)
18 my_struct.b = test;
(gdb)
19 my_struct.c = 23323.5235;
(gdb)
20 }
(gdb) info locals
value = 5
test = 512
my_struct = { a = 5, b = 512, c = 23323.5235 }
</pre>
