pragma message

[tb2000]

Just trying to get a handle on porting some libs to CE I woudl like to be
able to have #pragma message print out compiler directives like _MSC_VER or
UNDER_CE or (would be best) be able to dump any of those constants or
settings when invoking the compiler, just to check and debug the compile
environment.
Does anybody have an idea / suggestions?
I tried #pragma message ("and:" _MSC_VER ":")
but I am getting
C:\test\try1\testheader.h(6) : warning C4081: expected ')'; found 'constant'
from the compiler.
Thanks from a newbie!

Try this

x.c:
#define T(a) #a
#define S(a) T(a)
#pragma message (S(_MSC_VER))

c:> cl /c x.c
Microsoft (R) C/C++ Optimizing Compiler Version 14.00.50802 for MIPS
R-Series
Copyright (C) Microsoft Corporation. All rights reserved.

x.c
1400

The "#" is the stringify operator, it needs to be wrapped when applied to
macros.

Hope it could help,
benedetto

Thanks, I though there must be a way! That was helpful!

My 23 Feb 04 contribution to a thread called "Howto: place CPU-Type en
CE version in version header of the exe?" in
microsoft.public.windowsce.embedded.vc includes use of a pragma to
spit out info about the build. The line using pragma is way at the
bottom.

You can get the IDE to spit out most of the info. For eVC, it is
Project->Settings->C/C++->Customize->Suppress startup banner...
You want to uncheck the box, so you _don't_ suppress the banner.
