[Monetdb-developers] MonetDB project will move to monetdb.org

by Fabian Groffen

We would like to inform you that as of Januari 2013, the monetdb project on SourceForge will be removed. All services that SourceForge has kindly provided us with in the past will be migrated to our monetdb.org infrastructure. Currently, the only remaining services hosted on SourceForge are the three mailing lists monetdb-announce, monetdb-users and monetdb-developers. As of this message, these lists are migrated to their equivalents on monetdb.org. The new lists are as follows: monetdb-announce(a)lists.sourceforge.net -> announce-list(a)monetdb.org monetdb-users(a)lists.sourceforge.net -> users-list(a)monetdb.org monetdb-developers(a)lists.sourceforge.net -> developers-list(a)monetdb.org We invite you to subscribe to the new lists on monetdb.org at your earliest convenience. Any posts to the old lists are rejected from now on. Posts to the new lists at monetdb.org are forwarded in batches to the old lists until the end of this year. The MonetDB team would like to take this opportunity to thank SourceForge for the services provided over the past years. We hope to welcome all current subscribers on our new lists at monetdb.org, see: http://mail.monetdb.org/mailman/listinfo The MonetDB team

[Monetdb-developers] MonetDB on windows(visual studio 2010)

by 李珀瀚

Hi : I am a new user and I downloaded the newest version ( MonetDB-11.11.7 ).Because my main work is under windows , I want to test and use MonetDB on windows, too.I know that you supplied MonetDB5-SQL-Installer-x86_64-20120813.msi for users to install on windows and I tried it, it worked. But my question is that I want to explore the source code of MonetDB , I download MonetDB-11.11.7.zip<http://dev.monetdb.org/downloads/sources/Latest/MonetDB-11.11.7.zip> and there is a directory named NT,I entered and then enter the directory install64 , in there I found MonetDB5-SQL-Installer.sln and I I think this is the source which I can use to create a visual studio project. So I used Visual Studio 2012 to open it and then compile. The result is that I failed. So my question is :(1) how to trace MonetDB's source code on windows with VS 2010 ,do you have any suggstion? (2)After I installed MonetDB server and client , how could I debug the server(the problem is pretty much the same as the first)? Thank you! Pohan Li
