Re: [Mono-dev] EntryPointNotFoundException with __Internal method
hmm Thanks Robert! I was only adding --export-dynamic to generate the
intermediary .o files. Now I've added it to create the *nginx* executable.
Do you have any hints on the problem of Marshal.SizeOf returning 0 (zero)?
This is the class whose size is said to be zero:
*[StructLayout(LayoutKind.Sequential)]*
* public class NginxChain {*
* public NginxResponseBuffer buf;*
* public NginxChain next;*
* }*
NginxResponseBuffer is another class with sequential layout, although its
size is non-zero when calculated through Marshal.SizeOf.

You must link the main executable (nginx) with the the
-Wl,--export-dynamic
option, otherwise the dynamic linker won't expose its symbols to dlopen.
