Problems with PCH on Windows 2000 SP4

[Paul]

Dear world,

We are having issues with Windows 2000 SP4 and Pre-Compiled Header
(PCH) files that have been previously compiled on Windows XP using
..NET 2003. Recompiling the PCH files on Windows 2000 SP4 using /Yc
does work, but we really want to ship one PCH file to our customers
that will work on all versions of Windows.

Thanks very much

Paul.

PS The compiler output is below:
cl /c /G6 /O2 /W1 /Gd /vmg /MD /GX /EHs /DNO_STRICT /I"C:\Program

AFIAK, there's no guarantee that PCH files are portable off the machine
where they were created, regardless of OS vrersion. That you've been able
to do it at all is just luck. I'd like to be proven wrong about this - but
that's my understanding.

DO NOT SHIP PCH FILES!!

They are guaranteed to work only a single machine that has nothing change in
the interim (hotfix, SP, whatever to the OS, the compiler, the CLR or
anything else basically). They are simply a dump of memory at the time we
have generated the info. Anything that changes that memory layout will make
them incompatible.

Hi Ronald + Carl,

We have been shipping PCH files for some time now, but I think you are
right that we have been very lucky that most of our clients haven't
hit compile problems until now. We will be making changes to our
product to regenerate PCH files on the target platform.

Thanks very much for the quick response guys and it's also pleasing to
see to see somebody from Microsoft replying!

Best regards,

Paul :)
