This looks like MSVC won't like it.

Status Meeting (October 2013)
by Aleksey Bragin 31 Oct '13

31 Oct '13

Hello, Let me invite you to the monthly status meeting taking place last Thursday of this month, 31st of October, 19:00 UTC. Put that into your calendars so you don't forget. That's the last day of this month too and that's tomorrow! IRC service will only be started shortly before the meeting. Your participation passwords and server address will be emailed to you shortly before the meeting starts, and they are going to be different once again as they are not stored in any database. Hopefully it's not much of inconvenience. If someone still is not getting passwords sent before a meeting - please email Pierre or Colin (depending who will handle this meeting) before the meeting started to get one. The agenda will be posted shortly before the meeting, suggestions are welcome (send them to me shortly before the meeting starts). Regards, Aleksey Bragin

Servers unexpected downtime
by Pierre Schweitzer 29 Oct '13

29 Oct '13

Hi, North of Europa is facing a major storm. Currently, it is hitting Sweden where it is really violent. Unfortunately, some of our servers are there as well. Our datacenter has been affected (likely power issue) and two servers are currently offline and cannot be rebooted remotely. Our local sysadmin cannot make a move to the datacenter following the authorities recommandations to stay at home. So far, the following parts of our infrastructure are offline: -> Doxygen -> cppcheck -> ISO download -> ISO upload -> VMware testbots As a side effect, I will take the Linux builder & KVM testbot offline given it is impossible to upload any ISO at the moment. We will do our best to get the infrastructure back online as fast as possible. We will keep you informed. We are sorry for the caused inconvenience. With my best regards, -- Pierre Schweitzer<pierre at reactos.org> System Administrator ReactOS Foundation

Building and installing ReactOS on newer computer
by Thomas Mueller 28 Oct '13

28 Oct '13

How can I build and install ReactOS on a new computer? Can I install to a USB stick or to a 1.2 GB IDE hard drive in a USB 2.0 hard-drive enclosure? Main hard drive is Western Digital Green 3 TB, GPT-partitioned. I would have to build from FreeBSD or less likely NetBSD or Linux. I downloaded the installation ISO for ReactOS 0.3.15, but it failed to boot, also failed to boot on an old computer. I already have subversion (svn), built from FreeBSD ports. Tom

Thanks for response. Linux and the BSDs are not so fussy about where they are installed on, USB stick is OK. But I remember DOS, Windows and OS/2 were fussy. Do you use MinGW in Windows? MinGW, subversion, ninja and GCC are all available in FreeBSD ports collection. >From what I read, I think ReactOS might not get along with USB 3.0 and GPT, hence the desire to use a USB stick. FreeDOS also is difficult to install, many failed attempts on my computer perhaps related to modern hardware. FAT32 file system is not really good for making use of today's big hard drives. But keeping up with NTFS is difficult because NTFS is a moving target (I believe). I really feel more at home now with Linux and FreeBSD than with DOS, Windows or OS/2. Tom
