VSE2013: How to reduce exefile-size ?

ha

3/5/2016 12:53:00 AM

Hi

My programming language is c and cpp.

The system is Win7 Ultimate 64 Bit.


I am working with VisualStudioExpress 2013 and OpenWatcom.


The same sourcefile results with watcom in a much more smaller exefile-size
than VSE.

Is there a sort of "strip"-option, like "-s" in the gnu-compiler, for VSE ?

I tried all things, that are available via the VSE-GUI. But without success.

for sure it is\it must be compile for size\strip debug symbols\strip some startup code - those things, im not using VS at all so i cant answer directly which switches

If you're using a third party library, perhaps you've chosen the wrong one.
i.e. designed for an all-in-one solution library although you actually need
only a few functions/features of it.

No, I am using the default-configuration. It only links
the needed stuff.

How much smaller? Some compilers can just generate smaller code than others.

Try a utility such as PEDUMP or DUMPPE to look inside the executables,
and see what one includes that the other doesn't.

Maybe one statically includes a library, but the other only links to it
dynamically.

small halloworld exe should be afair of the size of 5kB or 10kB, stripped one (crt startup removed) more like 1KB

Thank you all, for answering


I forgot to say, that I disabled the c-runtime-lib in VSE.

*With* the CRT the resulted filesizes are even better than the ones, created
with watcom.


But I don't want to use the CRT in every case.

So the vse-sizes are more than almost three times big as the watcom-sizes.

Maybe, by switching off the crt, VSE uses without any cleverness all possible stuff,
so that the answer from "jj" gives the hint.

and what are the sizes (wit and without?)
i may say your post sound a bit lunatic;
for exampel are you sure that programming without crt is so easy (im not sure but does not most of things need that?)

You can choose. If you switch off crt, the linker will add the needed things automatically.

I fear, you have no idea, what crt means ? And so you say, my question is
lunatic?

on every machine, where an program which is set to "use crt" is used, you have to install that crt.

Without that, the program runs on every machine, whether it has crt installed or not.

i think we both are talking of msvcrt.dll (or equivalent)
but you seem to talking about static linking of such crt
as 'disabling' crt - which (if so) is confusing and thus not
proper i think

by switching-off/removing/disabling crt i personally mean
removing the crt from the exe (in gcc like -nostdlib is doing
that, c coding without that may be a bit harder (though probably not so much anyway))

Pay him no mind. There's at least one like him in every newsgroup.
