No, there was no actual support for it in the OpenCL code.
i thought the original already had lookup gap
I added support for LOOKUP_GAP to the scrypt-chacha kernel. This allows higher intensities and higher efficiency. I'm getting 35% more khashes/s out of my 7790.
scrypt-chacha.cl with support for LOOKUP_GAP
https://mega.co.nz/#!l0sixSoQ!Xzzic2-GwMfGu3kefL8A1HmZuC8fuE3tlKiHdVO8-7M
How to use:
1. Download the new kernel file.
2. Rename to scrypt-chacha.cl.
3. Copy to your GPU miner folder.
4. Delete any .bin files.
5. Restart your miner.
6. Adjust intensity.

It's not easy task 
You can try rollback the changes and compile and run, to see if have these errors.
Then add the set of changes, one by one, when adding each one, compile & run, to see if have these errors.
This will help you identify which step you make a mistake. Then trying to correct it. I'll go sleep now ...

Add static modifier to these multiple definitions.
For example,
static void GetNfactor(...)
static int nChainStartTime ...
wow, that got it to compile thanks....but hehehe it refuses to play ball

... have changed the anything about the kernel parameters? Did you just download the yaminer-beta-src-2.zip and modify?
Yeah i used he one you uploaded

how to tweak for onecoin?
I found it needs some work for onecoin, onecoin uses salsa mixing not chacha mixing. Hash function is same both are keccak-512.
so is it feasible or maybe not worth the effort?
It's of course feasible. I just hope there're some one else can hack it if he's interested. Because my kernel is presented in a very clear way.
Just replace the chacha core with the salsa core, I think just that easy. After that, the Nfactor calculation needs to be changed also.
Because I don't have any onecoin position, I don't really have intention to do that.
i'll give it a crack, any pointers on where to look?
CL kernel file: scrypt-chacha.cl, find the function `static void chacha_core(uint4 state[4])`, trying to replace it with the function `static void salsa_core_basic(uint32_t state[16])` from file scrypt-jane\code\scrypt-jane-mix_salsa.h
scrypt.c, driver-opencl.c: GetNfactor(unsigned int nTimestamp), change to the function in onecoin.
I think basically these two places, other parameter to the scrypt hash seems to be the same like the rfactor, pfactor both are 0.
ok i got the first part and third part done but i cant find the function GetNfactor(unsigned int nTimestamp) in scrypt.c (onecoin)
It's in the main.cpp? Or search for it.

thanks a lot, never messed with cgminer before, i'll tell you if i'm succesful and if i mine a few coin i'll throw some your way.
Cool, if you met some difficulty, let me know.
One last thing: the chacha_core in scrypt.c should also be replaced to salsa_core_basic.
