Odd. Is that on a Mac?

Linux

Which GCC version?

Red/System (current master, g0c9c1bf): 2.5s
GCC 4.8.1 -O0: 1.9s
Clang 3.3 -O0: 1.6s
Clang 3.3 -O2: 0.6s
GCC 4.8.1 -O2: 0.5s

So there's a much bigger difference between optimised and unoptimised 
versions than in previous tests

I was on an older GCC version then, 4.1.2 or 4.2.3

Xie is on Windows, and his compiler is apparently called cl. XieQ, 
is that CLang? Which version?

That's MSVC.

Perhaps GCC has gotten better at optimisation

Compared to 6-year old GCC 4.1.2, it certainly has improved a lot.

Just dug one of your Fibonacci results from back in Feb-2012, that 
used GCC 4.43.

dug up*

Oh, don't remember that

Ah, it must have been GoboLinux's GCC

You mentioned the benchmarks running on Syllable Server.

Yes, that's why I thought 4.2.3. But I would have tried them on Syllable 
Workstation on top of Syllable Server

That's an unreleased GoboLinux-on-Syllable-Server FrankenLinux

So it's a pretty big difference in optimisation, and MSVC doesn't 
show it

I use VS2012 and it's MSVC ver 17.

Thanks

We

 are a team! Yoho!! According to Frank Ruben on the Red mailinglist. 
 He has a question about interfacing a C app in Red/System.

Now in Red/System, we can't pass a function as parameter to Red/System 
FUNC,
but we can pass it to external C FUNC, right?


cmp-func!: alias function! [left [byte-ptr!] rihgt [byte-ptr!] return: 
[integer!]] 
quick-sort: func [
	base	 [byte-ptr!]
	n		 [integer!]
	size	 [integer!]
	cmp-func [cmp-func!]	
][
	; can't use cmp-func in this function
]

XieQ, that should work too.

You should try passing the function! pointer as integer! then type-cast 
it inside the function. IIRC, function! cannot be  yet used in a 
Red/System func spec block.

(But as you mentioned, function! is accepted for external functions)

I write a simple test  try to understand it, it's can be compiled, 
but the output is not expected

Red/System []


cmp-func!: alias function! [left [byte-ptr!] right [byte-ptr!] return: 
[integer!]]

cmp-int: func [
	left [byte-ptr!] right [byte-ptr!]
	return: [integer!]
	/local a b
][
	a: as int-ptr! left
	b: as int-ptr! right
	a/value - b/value
]

bar: func [
	cmp-func [cmp-func!]
][
	a: 1
	b: 2
	print cmp-func :a :b
]

bar :cmp-int

XieQ - that's what Doc stated, no? you use cmp-func! function type 
in func spec block, which is not allowed (except the external functions, 
whatever that means). Sorry if misunderstood on my side, just trying 
to point that out ...

it's print a memery address ( 00401A8F in my windows 7)

Pekr, I will try again

Yes, because the compiler is not yet able to process `cmp-func [cmp-func!]` 
correctly. Try to declare an integer! there and then type cast it 
to a cmp-func! inside the body.

Got the right result! Thanks Doc

bar: func [
	cmp-func [integer!]
	/local compare result
][
	a: 1
	b: 2
	compare: as cmp-func! cmp-func
	result: compare as byte-ptr! :a as byte-ptr! :b
	print result
]

bar as-integer :cmp-int

I guess I should complete the function! support at some point before 
starting on Red/System 2.0.

New try for the Red port on Android demo:
http://static.red-lang.org/hello2.apk


This time it should work fine on all devices, please let me know 
if you find any issues. Just be sure to uninstall previous version 
before installing this one (just to be sure you won't report false 
positives).

Source code for the demo: http://pastebin.com/R5ySC8sw

I'm happy to confirm that this now works on my Nexus 4 :)

Great! :)

Nice! works fine on all my devices (my phone 2.3.7 and my pad 4.1.1)

Good, so we're almost ready to start infecting the Android world 
with the Red virus. ;-)

Works on Samsung S3 Galaxy, Android 2.3.6

doesn't work on my 4S 5.01  ;-)

Actually it does even on your 4S using iAndroid emulator: http://www.youtube.com/watch?v=gehh6zIijXM
;-)

Endo, thanks for testing it.

It still won't install on my Galaxy Nexus with 4.2.2.

AdrianS: do you have a previous version already installed? What is 
the installation error message?

It's a very nondescript message - "App not installed"

The only reasons I can think of for that issue are:
1) Not enough internal memory available for new apps.
2) You have a debug version of the same app already installed.

Also, you might want to check if you have allowed installation of 
apps from "unstrusted sources". You need to have that option checked 
to be able to install apps coming from outside of the PlayStore.
