Ok I am sure someone is going to be able to tell me that there is something else I can do here to reduce the size from 367KB.

I compiled dmc hello -o+space & dmc hello -o

both file sizes were almost the same, the -o+space was slightly higher by a few bytes.

I know in GCC you can pass -s to the linker to strip symbols to reduce the exe, is there something similar in dmc or is 367KB the best I can hope for in a 5 line console ??

I am not overly bothered size isnt everything <g> as I discovered a slightly larger program 10 lines does not increase excessivley over the 367KB

Any ideas please ?

You have a file called "hello" containing the source? Are you using the C runtime or C++ iostream for output?

If it's C++, you have your answer...the implementation. I still have not found a mildly-sized C++ iostream. Use printf instead.

I wrote a hello world with printf and then with iostream, using stlport and dmc 8.35:

printf:  38 KB
cout:   366 KB

You can try the printf/cout test with most compilers, and I guarantee that you will mostly get higher footprints for the iostream use. Bjarne Stroustrup says (in The C++ Programming Language), that this is a misconception and it's all based on your library provider. Well, I've used a lot of different compilers/libraries and always have seen the same thing. Think about printf/scanf over the cout/cin family.

Oh c'mon!
I used the STL included with DMC.

dmc hello.cpp -Nc -6 -o

With my stubborn Hello program, result:

.exe 48156 bytes
.obj 829 bytes

With a standard hello world:
.exe 47132 bytes
.obj 376 bytes


Stubborn Hello Source:
--- 8< ---

#include <iostream.h>

int main (int argc, char *argv[]) {
    char quit = '\0';

    while (quit != 'q')     {
        cout << "Hello ! This is a very simple but stubborn console app." << endl;
        cout << "\tPress q to quit " << endl;
        cin >> quit;
    }

    return 0;
}

--- >8 ---

-i.

Are you using the default SGI Library or STLPort?

Nope you are correct iostream in C++

Indeed I a also using the STLPort library thanks for taking the time to check it out.

Like I say I am not to bothered, as larger programs do not grow exponentially only very small increments

Thanks

Hmmm

Much fiddling later in IDDE and I have managed to get exe to 18kb

How?

In project settings set use dll runtime library ans et voilla 18kb however if you use the system ( "PAUSE" ) ; in program it crashes ouch but if you use cin >> some int ; it doesn't, anyone know what causes this ???

cheers

So you use IDDE. Command-line rules!

Walter already said the DLL RTL support was broken.

I was considering to make the compiler use Microsoft DLL RTL which is delivered with Windows - because it is the only way to make the compiler qualify for 64k-demos. If not RTL issue, DigitalMars would be the best compiler for such things around!

-i.

<g> yes, I could get prog to compile in about 18kb with command line before, but wanted to use the idde, well if you got it use it, I say <g>

Sorry I missed that one dute

googled for this bit about rtl dll broken, could not find owt on it though, is it planned to be fixed in th future ?
