Hello everybody

 

Because I need share sources from C#-Windows and Xamarin-Android, I’ve
decided try to compile Firebird sources in Visual Studio Cross-Platform and
test it.

>From the Windows version projects structure, I’ve used the sources list of
makefile Linux projects and the auto generated sources files of Mariuz
method.

Actually, I’ve been able to compile ok, making a few changes on source code.

On the other hand, I’ve compile de .NET provider to Android too making a few
changes on source code.

I’ve three goals:

Goal 1: Android client and Windows/Linux server -> Compiled, running and a
few test.

Goal 2: Android embedded server -> Compiled and debugging 

Goal 3: Android server and any platform client -> Compiled but not tested
yet

 

The Goal 2:

 

I’ve been able to create a new Database and afterward the program crash. The
Database integrity is ok. I’ve pulled it from Android Virtual Machine and
put into Windows server to confirm it.

I’ve been able to open the created Database and afterward the program crash.

 

The status vector returned to the NET Provider, tell me “isc_bad_db_handle =
335544324L”. After a few time debugging, I’ve seen that the handle returned
from “isc_...” functions like create or attach database, is not reusable for
isc_detach_database (is called after create,  then crash -commented above-)
or for isc_database_info (is called after open, then crash -commented
above-).

>From the NET Provider, the “ref _handle” seems be ok before the call to
native libfbclient.so into why.cpp file (values 1 or 2 are shown by Visual
Studio debugger) . In Windows debug, the value stored in the handle continue
being the same after native call. However, the handle value stored in
Android debug is 0, and exception/error is raise in status vector.

 

Any ideas?

Thanks
