DocKimbel 23-Aug-2012 [1212x4] | Works fine here. I'm testing with: Red/System [ ] i: 56 foo: func [a [integer!] return: [integer!]][a + 1] #export [foo i] |
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. | |
Rebolek 23-Aug-2012 [1216x4] | 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) | |
DocKimbel 23-Aug-2012 [1220] | 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 |
Rebolek 23-Aug-2012 [1221] | Hm, I'll try with 2.7.6, I'm using 2.7.8 this may be the problem. |
DocKimbel 23-Aug-2012 [1222x2] | 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. | |
Rebolek 23-Aug-2012 [1224] | 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. |
DocKimbel 23-Aug-2012 [1225x4] | 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) | |
Rebolek 23-Aug-2012 [1229] | No, W7. I will try this under virtual XP |
DocKimbel 23-Aug-2012 [1230x3] | 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? | |
Rebolek 23-Aug-2012 [1233x2] | 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 | |
DocKimbel 23-Aug-2012 [1235x5] | 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. | |
Rebolek 23-Aug-2012 [1240] | 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 :) |
DocKimbel 23-Aug-2012 [1241x2] | :-) |
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. | |
Pekr 23-Aug-2012 [1243x2] | 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 ... | |
Rebolek 23-Aug-2012 [1245] | Petr, can you please try loading the DLL I provided, so we're sure it's just som eproblem with my setup? |
Endo 23-Aug-2012 [1246] | I've successfully loaded the temp.dll, R2 2.7.8 on XP/Pro. |
DocKimbel 23-Aug-2012 [1247] | It's strange that it didn''t work for Rebolek even on its WinXP virtual image...do you have an antivirus installed there? |
Endo 23-Aug-2012 [1248x4] | 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. | |
MagnussonC 23-Aug-2012 [1252] | lib: do load/library %temp.dll ** Script Error: MZ€ has no value ** Near: lib: do load/library %temp.dll |
Endo 23-Aug-2012 [1253] | You are trying with Rebol/Core I think. it doesn't support library. Try with View instead. |
MagnussonC 23-Aug-2012 [1254] | Ah.. |
Endo 23-Aug-2012 [1255] | Rebolek: You are using View, right? |
MagnussonC 23-Aug-2012 [1256] | I'll try with view ... |
Rebolek 23-Aug-2012 [1257x3] | 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 :) | |
MagnussonC 23-Aug-2012 [1260x2] | 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. | |
