[Mono-list] Web Services and native shared objects: System.DllNotFoundException

[Miquel Ramírez]

Thanks for the tip, but I fixed it by 'exhaustive search' i.e. reading
exhaustively all mono manpages :) Then I realized I had forgot to add
the following:

<configuration>
        <!-- snipped -->
        <dllmap dll="CsharpFrontend.dll" target="libCppBackend.so"/>
</configuration>

libCppBackend.so was already placed in a "smart" place: $(MONO_PREFIX)/lib.

Thanks!

Miguel.

PS: I solved the logging issue (to some extent) by relying on log4net
[http://logging.apache.org/log4net]. Better than having
Console.WriteLines all over the place ...
PS2: Also tried the <trace> feature in the web service 'descriptor'
but it just traced the messages passed forth and back the server :(
