[Mono-dev] EntryPointNotFoundException with __Internal method

[Marcelo Zabani]

When embedding Mono within Nginx, I received the following exception:

*Unhandled Exception: System.EntryPointNotFoundException:
log_error_core_wrapper*
*  at (wrapper managed-to-native) Nam.NginxMethods:ngx_log_error
(uint,intptr,int,string)*
*  at Nam.NginxMethods.LogInfo (IntPtr log, System.String msg) [0x00000] in
<filename unknown>:0 *

The DllImported method is this:

*[DllImport ("__Internal", EntryPoint="log_error_core_wrapper")]*
*public static extern void ngx_log_error(uint level, IntPtr log, int err,
string msg);*

As for the executable:

*$ nm nginx | grep log_error_core_wrapper*
*0000000000463267 T log_error_core_wrapper*

Please note that log_error_core_wrapper is a function of mine that calls
another nginx function.

What am I missing here?
Also, I keep getting
*Marshal.SizeOf(typeof(some_non_empty_class_with_layoutkind_sequential))
== 0*. Are there any hints as to what this could be?

Thanks a lot.
