Arnold, there is not one account for red.esperconsultancy.nl. Each 
Fossil repository under there has its own account system. But you 
don't need accounts for reading; they're public repositories

Yes I understand now. Is it possible to have a page linking to all 
the Red repositories? 

Alternative is have a special Red-info group with all of the links 
to various Red sites. The repositories, Issue list, Wish list etc 
etc.

The incomplete Contributions page on the Red site is all there is 
so far

I was going to set up a bindings site, but Doc wanted me to work 
on Android support

However, as I've explained before, all repositories follow the same 
naming pattern. If a dependency is #included from a common/ directory 
it's in the Red-common repository

And there's a complete list of all my repositories in my download.r 
script, which you can use to download and update them all in one 
go:

Great work on Android, Doc, and nice tweak, Petr :-)

I am surprised that sometimes I can be somehow usefull :-)

:-)

Kaj, thanks! We're about half-way to the full Android Red support 
I have in mind, but it's already usable if you don't mind going through 
the Android API. Fortunately, we'll make that part vanish too with 
some nice high-level abstractions.

Doc, Henrik asks about RPi support, in case it runs Android. Will 
it run?

It's in the FB group ....

The Raspberry hardly runs Android

They say it runs a little, but I've tried it and it's so bad you 
might as well say it doesn't run

Inasfar as it does run, there's no reason Red wouldn't run on it 
now

Doc, what's your timeline on the full support you have in mind?

I need to have objects and ports implemented first, so don't expect 
it before September most probably.

Thanks. So it's not as if it is next year. Where can I see the red 
code for your second hello?

I've renamed it to `eval`, it's in red/bridges/android/samples/eval/.

Thanks for the help everyone, esp. Kaj.  Changing to 'allocate was 
all I needed for my program to work.  Thanks to Doc for the debugging 
hint (run from MS-DOS console).  Don't know why I didn't think of 
that on my own.

Doc, I must be in some other world. Where is red/bridges?

I checked the pastebin link and saw the code.

It's in the dyn-lib-emitter branch. I guess you were looking in master?

https://github.com/dockimbel/Red/tree/dyn-lib-emitter/red/bridges/android/samples/eval

Kaj, thanks. Yes, I was in master! Perfect.

Almost the same as another world ;-)

When you're lost it is exactly the same. The problem with me is that 
I come in and out of these conversations and so end up not building 
on top of previous knowledge. Every trip into red-landia is a new 
one :-)

While I am at it, I'm on the dyn-lib-emitter page, is there something 
I click on to download the entire dyn-lib folder?

Nevermind. I just created an account and now see the zip button.

I thought it worked without an account. But I haven't been logged 
out for a long time

I don't know if I am using it correctly but I attempted to run the 
build.r file (w/o any arguments...I think it builds the "eval.red"). 
I end up with:
Signing apk...
'jarsigner' is not recognized as an internal or external command,
operable program or batch file.
Aligning apk...
Unable to open 'builds\eval-signed.apk' as zip archive

It should have downloaded the jarsigner and other tools

Do you have a JDK installed?

Interesting, the lines for downloading that are commented out. I 
will try it again. I do have the JDK installed as I was doing some 
driod app stuff a while back.

Seems a mistake

Wonder how it worked for Petr

Getting closer. I now have jarsigner but the cmd expected to see 
it in the root dir. So I just placed jarsigner there along with the 
jli.dll.  That may not be a good idea because it seems to do its 
thing but finally dies with:
Signing apk...

Error: Could not find or load main class sun.security.tools.JarSigner
Aligning apk...
Unable to open 'builds\eval-signed.apk' as zip archive

Looks like Doc and Petr had jarsigner already installed with their 
tool suite

At this point I am stuck on the sun.security.tools.JarSigner file 
issue.

OK.  Next enigma about Red/System that I ran into.  Consider the 
two following sets of code and output.  Why are they different?

Code 1:
	im1: as-integer ((img1/r / 3) + (img1/g / 3) + (img1/b / 3))

 print-line as-integer ((img1/r / 3) + (img1/g / 3) + (img1/b / 3))

Output 1:
...
96
99
107
111
105
104
100
99
100
98

Code 2:
	im1: as-integer ((img1/r / 3) + (img1/g / 3) + (img1/b / 3))
	print-line im1

Output 2:
...
4260192
4260451
4260203
4260207
4259945
4259944
4259940
4260451
4260196
4260194

The example is not complete. How do you get more than one value?

This is a loop that processes raw binary image data.  'r, 'g, and 
'b are incremented through an 'until loop until the data is all consumed.

But what is troubling to me is that

print-line im1

is not equal to


print-line as-integer ((img1/r / 3) + (img1/g / 3) + (img1/b / 3))

They should be equivalent.

It could be a Red/System bug, or it could be a result of the code 
you're not showing. Can't tell

Are you doing this on the Raspberry? Doc recently made fixes to the 
ARM code emitter. It was less mature than the x86 emitter

I am running this on Windows currently.  XP 32-bit.  Here's the complete 
code:

#include #../C-library/ANSI.reds

img1: as-binary 0
size1: 0

img1: read-file-binary "img1.bin" :size1

i: 0
r: 0
g: 0
b: 0
im1: 0
until [
	r: i + 2
	g: i + 3
	b: i + 4
	im1: as-integer ((img1/r / 3) + (img1/g / 3) + (img1/b / 3))

 print-line im1 ;as-integer ((img1/r / 3) + (img1/g / 3) + (img1/b 
 / 3))
	i: i + 4
	i >= size1
]

If I change the line


 print-line im1 ;as-integer ((img1/r / 3) + (img1/g / 3) + (img1/b 
 / 3))

to


 print-line as-integer ((img1/r / 3) + (img1/g / 3) + (img1/b / 3))

I get the expected output.

It could be caused by differences in the auto-casting between a simple 
assignment and a call to print-line.

Being conservative I would have written:


im1: (((as integer img1/r ) / 3) + (as integer img1/g) / 3) + (as 
integer img1/b) / 3)
