Why did everyone suddenly decide TCC is the best compiler for demos / size optimized executables? It's not!

Everyone? It's only me using it!
Everyone else is suggesting me to use other compilers with full size optimization and stuff, but I'm just that retarded and confused that I stick to TCC

But... but... IT'S TINY!

I don't know why zeeky said it's probably not meant to optimize size.. that's one of its goals.

Its the easiest to use tho, I just tried compiling hello world with gcc and the commands -Os -fno-inline -nostdinc -fomit-frame-pointer as told in the WDYNHW thread and it says it cant fint stdio.h
using -Os only made the exe 19kb while tcc makes it 1.2kb

[ThePuska]

If you included -s in that list of commands, or ran strip yourself after gcc, you would notice that the filesize drops significantly. GCC gave me something like 6kb without much work on my part, the same as Visual C++ without any extra work. Replacing Visual C++'s linker with Crinkler dropped the filesize below 1kb.


edit:

This without any previous experience with GCC or Visual C++ or even the C language

-nostdinc

it cant fint stdio.h

lol

Edited:

if you don't get the hint, -nostdinc means no standard library inclusion meaning it's not supposed to find stdio.h with that option.

Haha yea i got that, but in that case its a pointles command. Most if not all programs would use the standard library somewhere.

I'm more interested in 64k demos and demos without size limits.

I'm sure I've posted ASD Lifeforce before in some WAYWO, but here it is anyway, because I love it; especially the music:

http://www.pouet.net/prod.php?which=31571
Other demos by ASD are also very nice.

My personal favorite from last year:

This is one that you might want to watch on your own hardware, if you've got a high-end graphics card with a lot of memory that is.
http://www.pouet.net/prod.php?which=55558

And one of my favorite 64k's:

If you watch this one on your own PC, beware of false anti-virus positives. I assume it's because the packer it uses has been used to pack malware in the past.

wtf just use vc++

Edited:

also, anyone know how i can make a .net assembly as small as possible without compressing it? i'm shoving assemblies into object files to see how crinkler handles them. i took a small winforms app and managed to compress the cil from 9436 to 3972 with metadata intact.

eventually i want to figure out how to invoke the clr on it.

Finally decided to read this thread. For those of you on Windows trying to get the smallest executable, take a look at this

It's done in the same spirit as the tiny elf (for Linux and FreeBSD) and the tiny mach-o (For Darwin based operating systems) projects.

You'll learn a lot, I promise. :)

Edited:

You may also find these pdfs interesting.
(Yes I realize the Mach-O link is to html. just go with it)

This thread is awesome.
I love how this shit started with the cracker scene (Razor, Skidrow, etc) and evolved into it's own scene.

Is his use of "what" a valid English dialect somewhere, or does he just have some vendetta against the word "which"?

[Darwin226]

It says he's not a native English speaker right there on the first page.

Not sure how I missed that.

Went to Assembly Summer last year, biggest demoscene/lan party in Finland. Going there again this year.

Demos are nice, but they're even nicer on a big-ass fucking screen that's measured in meters instead of inches.
(Note: they're not nice on the big screen if you're in the audience trying to fucking sleep).

The Finnish indie game industry and demoscene is small. There's some overlap between the makers of Zen Bondage and Zen Bound.
