Hi all,
I have been running Windows 7 beta for a few weeks now at home (being
the eternal early adopter at heart :-) ), and I just tried to compile
and run OSG on it. Everything seems fine in debug, but I'm hitting one
little snag in release mode.
The exact problem is discussed at length on this page:
http://www.wintellect.com/CS/blogs/jrobbins/archive/2009/01/24/the-case-of-the-corrupt-pe-binaries.aspx
(note that I'm using Visual Studio 2005 SP1, but the problem is exactly
the same)
The short version is that after linking executables, when mt.exe is
called to include the manifest into them, the executables somehow get
corrupted (see the link above for the exact explanation) and I get the
following error message:
mt.exe : general error c101008d: Failed to write the updated manifest to
the resource of file "<executable file name>". The binary is not a valid
Windows image.
This happens for every executable, every time.
According to that same link above, there are two ways to work around
this apparent bug:
1. Enable /DYNAMICBASE in the linker options (the bug happens when using
/DYNAMICBASE:NO, which apparently is the default in our case)
2. Include an empty RC file in each project.
I'd like to add /DYNAMICBASE into the CMake config (perhaps only for
Windows 7 if that can be detected, and perhaps conditionally so we can
remove the workaround when/if the bug gets fixed), but I wanted to get
opinions. What do others think would be the best course of action (other
than waiting for the official release of Windows 7 ;-) )? Are there any
drawbacks to specifically linking with the /DYNAMICBASE option? I'm not
familiar with this option, and the MSDN page does not have any
recommendations of when to use it and when not to, it just describes it.

If I get no opinions I'll just submit a modified CMakeLists.txt that
includes /DYNAMICBASE.
Thanks in advance,
J-S
