Hi there,
This patch is to blame (seems to, just this) or another...
But trunk is broken: build stops with these messages:

Are you sure?
http://www.reactos.org/getbuilds/  has rev53904 built.
Your issue might be compiler or build system specific ofcourse.
53901 (Debug, Cmake, BootCD) worked fine for me in VMWare (with
exception of Gecko failing to install on 64MB yet succeeding at 128MB).

You need to clean freeldr_arch and freeldr_base.
Or use cmake :)

Initially I cleaned these directories, then cleaned all, by make
clean. ...same result.
Maybe all of you use cmake? :)
BTW is switching to cmake already performed?

I had the same issues. Just run "clean" and that will fix it (at the expense of
a full rebuild). I also tried "make freeldr_clean (and setupldr) with no luck. I
think the problem is from how weird the freeldr rbuild files are done.

Why are there still 2 build systems?
It's been like this for 3 or 4 months now and you still have the problem
where some people are using rbuild and some people are using cmake.
Is it because writing an OS is too easy and you all need more of a
challenge?
You now have the following developer configurations:
Build System    Compiler        Platform
rbuild          gcc             windows
rbuild          gcc             linux
cmake           gcc             windows
cmake           gcc             linux
cmake           msvc            windows
Add to that 4 different flavours of developer virtual machine and it's no
wonder you're constantly tripping up over each other.
I'm sure you all don't want to hear me rant about best practice and how this
should be fixed, but someone needs to step in and try to define some sort of
base development platform.

If you were

No, we don't want to hear you to rant.
Ranting is something we can prefectly do ourselves, and it doesn't help
fixing the problem, believe me, I've tried ;-)
Instead you could have come up with a practical solution month ago. Or
even better fix the issue.
Hint: it's not like BEs fall from the sky and buildbot scripts are
generating themselves.

Timo

Very helpful. Thanks for the explanation Alex.

Well maybe it would help to fix the problem if someone pointed out why this
is a bad idea instead of ranting about things like "you broke the cmake
build" or "well it works fine with rbuild on windows" or "someone
broke the
linux build machine again"

I'll fix the issue quite simply. Until cmake is ready, it shouldn't be used
by anyone for development.
If it's still work in progress then it's not part of the official toolset
and should be treated as being broken.
You can't have half of the developers using one thing and the other half
using another.
Everyone working on reactos should be using the same build environment,
which is also the build environment that the build machine should be using.
Anyone who chooses to move away from this environment is more than welcome
to, but any issues this brings are for those people to solve along with the
help of the willing community.

I will try an educated guess:
