You're sure that you're in `dyn-lib-emitter` branch?

(just in case)

If you still can't make it work, send me a copy of your DLL, I'll 
see what's wrong with it.

Yes, I'm in dyn-lib-emitter branch, otherwise compiler throws #export 
directive not found (or something like that)

My DLL is almost same as your example ('i is missing and function 
is called 'f1 instead of 'foo but otherwise it exactly same :)

RED/System[
	Title: "RED/System inline compilator test"
]

f1: func [a [integer!] return: [integer!]] [a + 1]
#export [f1]

(FYI: I'm trying to implement your make-native example)

Your code works fine here (REBOL 2.7.6): 

>> lib: load/library %builds/test.dll
>> f1: make routine! [a [integer!] return: [integer!]] lib "f1"
>> f1 123
== 124

Hm, I'll try with 2.7.6, I'm using 2.7.8 this may be the problem.

Works here from 2.7.8 too. Try from a freshly cloned repo.

Or just send me a copy of your DLL at [nr-:-red-lang-:-org], I should be 
able to quickly see what's wrong.

The DLL is here: http://box.lebeda.ws/~rebolek/temp.dll
source is here: http://box.lebeda.ws/~rebolek/temp.reds
But I guess it's just some stupid mistake on my side.

Let see that...

Works fine here: 

>> lib: load/library %builds/temp.dll
>> f1: make routine! [a [integer!] return: [integer!]] lib "f1"
>> f1 123
== 124

Are you running it under Windows XP?

(I wonder if it's not an OS compatibility issue)

No, W7. I will try this under virtual XP

I'm running it under W7 too, should be ok.

Mystery deepens...:-)

Are you preloading other DLL in your REBOL session before loading 
temp.dll?

Same under WXP (virtual) with both 2.7.6 and 2.7.8 . It's probably 
some bad day :)

>> lib: load/library %temp.dll
** Access Error: Cannot open temp.dll as library
** Near: lib: load/library %temp.dll

No, clear session

hmm...

Try with following C executable:  http://static.red-lang.org/tmp/loadlib.exe
(or .zip if you have issue downloading the exe).


Put it in the same folder as temp.dll and run it from DOS shell, 
you should have something like: 

C:\Dev\Red\red-system\builds>loadlib
error: 0
hModule: 268435456				;-- library handler
error: 0
&f1: 10001a85				;-- f1 function address
124						;-- f1(123)
error: 0

If it works, the DLL should be ok and the issue would be with your 
REBOL instances.

This is the source code for loadlib.exe: https://gist.github.com/3435800

Also, if someone else could test loading Rebolek's temp.dll lib, 
that would help.

Guess what. That works:

c:\code\Red\red-system\builds>loadlib.exe temp.dll
error: 0
hModule: 268435456
error: 0
&f1: 10001a85
124
error: 0

So it's probably really a bad day here for coding/testing :)

:-)

The only cause I can think of is because the DLL produced by Red/System 
are not (yet) relocatable, they can be conflicting with other loaded 
DLLs (but shouldn't happen with a fresh REBOL session), or are triggering 
something in anti-virus or Windows security sub-systems.

One thing - between some versions, there was change in syntax of 
"renturn". One version used the colon, the other did not. Just an 
idea ...

but if the same code works for Doc, problem is elsewhere ...

Petr, can you please try loading the DLL I provided, so we're sure 
it's just som eproblem with my setup?

I've successfully loaded the temp.dll, R2 2.7.8 on XP/Pro.

It's strange that it didn''t work for Rebolek even on its WinXP virtual 
image...do you have an antivirus installed there?

I have Avast on my PC.

Rebolek: if you have a antivirus, can you disable it and try?

Can it be msvcrt.dll version?

Try to watch what happens when loading the dll using Process Monitor 
and File Monitor from System Internals.

lib: do load/library %temp.dll
** Script Error: MZ€ has no value
** Near: lib: do load/library %temp.dll

You are trying with Rebol/Core I think. it doesn't support library. 
Try with View instead.

Ah..

Rebolek: You are using View, right?

I'll try with view ...

Endo, Nenad: no antivirus. Yes, I'm using View.

Anyway, if it works for everybody else, it's just probably some problem 
with my setup. I'll investigate it and let you know.

Sorry for the false alarm :)

I don't get any output, just a question if I'm allowing to open a 
port for read/write ...

I'm on Win 7 x64 & rebol-view-278-3-1... Never mind me, I'm just 
fooling around with this.

I am getting the same problem as REBOLEK
