Hi,
I am trying to embed mono... and I ran into a problem with the code:
monoMethodDesc = mono_method_desc_new("Script:Main", 0);
method = mono_method_desc_search_in_image(monoMethodDesc,
monoEngine->image);
It is returning a method on the cs code:
public class Script
{
static public void Main ()
{
ScriptEngine.report("--Main Called ");
}
}
but it is also returning a method on the cs code (with the wrong class
name):
public class Script*2*
{
static public void Main ()
{
ScriptEngine.report("--Main Called ");
}
}
while it should only return for:
monoMethodDesc = mono_method_desc_new("Script2:Main", 0);
Am i doing something wrong or is this a bug? It seem that
mono_method_desc_search_in_image is returning a value if the actual
class name is starting with the given class name.... so, the same
method is returned if I look for "Script:Main" but the declared class is
"Script:Main", "Script_test:Main" or "Script2:Main"...
and a question:
is there a way to know if mono_domain_unload was successful or not?
I am creating an app domain per script so that I can recompile and
reload the script at will...
I do not detect any error, but the new script seems not to replace the
old one...
Basically, I am doing:
res = mono_domain_set(rootDomain, FALSE);
mono_domain_unload(monoEngine->domain);
monoEngine->domain =
mono_domain_create_appdomain("ScriptEngine-sub", NULL);
data = readFile(f, &dataLen);
fclose(f);
monoEngine->image = mono_image_open_from_data_with_name(data, dataLen,
TRUE /* copy data */,
&status,
FALSE /* ref only */,
monoEngine->fileName);
free(data);
if (status != MONO_IMAGE_OK || monoEngine->image == NULL)
{
return FALSE;
}
// load the assembly
monoEngine->assembly =
mono_assembly_load_from_full(monoEngine->image,
monoEngine->fileName,
&status, FALSE);
if (status != MONO_IMAGE_OK || monoEngine->assembly == NULL)
{
mono_image_close(monoEngine->image);
return FALSE;
}
but it does not seem to work. The code that runs is always the first
loaded one!!
I also added the following code to my engine:
mono_trace_set_log_handler(monoLogCallback, NULL);
mono_trace_set_print_handler(monoPrintCallback);
mono_trace_set_printerr_handler(monoPrintCallback);
mono_trace_set_level_string ("debug");
but it is reporting debug info only on the first run... is there a way
to having it working on every run?
Lastly, Is there a way to compile cs source without launching a
system("msc.code.cs -target:library");
thanks in advance
Pierre
