sure mate here it is
http://www.linuxfromscratch.org/blfs/view/7.4/postlfs/openssl.htmlHello mate,
do you mind sharing which website you have downloaded and copied that file (bn.h) in detail (if possible with steps, may help other users too).
Thanks

One Page back...I sorted the issue by downloading openssl 1.0.1 from their website and copying the "bn.h" after install to \usr\local\include\openssl
It then builds without issue. Hope it helps

Thanks both of you, I've managed to build it too, if any one interested happy to share step by step detail

Would be great if you could post a how-to here!
This is how it worked for me, increase is quite nice plus 3-4 MH/s vs palgin mod, getting 29-30 MH/s with 1070.
To avoid error I needed to update one openssl file to past version:
wget http://www.openssl.org/source/openssl-1.0.1e.tar.gz
tar -xvzf openssl-1.0.1e.tar.gz
cp /usr/local/include/openssl/bn.h bn.h.backup
sudo cp openssl-1.0.1e/crypto/bn/bn.h /usr/local/include/openssl/
git clone https://github.com/krnlx/ccminer-skunk-krnlx.git
cd ccminer-skunk-krnlx/
sudo ./build.sh
Now test it and if it works, stop miner (pkill -e miner) and copy over and wait for miner to restart and Voilà!

pkill -e miner
./ccminer
sudo cp ccminer-krnlx/ccminer-skunk-krnlx/ccminer TPccminer/
If it works and you wish to thank me, go and check out my project
https://cryptopanic.com/Thanks for posting this info - I banged my head against a wall for quite a while trying to figure this error out before giving up on it. This worked like a charm for me.
Though I think I'm still getting really low hashrates for skunk - whattomine thinks I should be getting 450mh/s with 5 1080 Tis and 7 1070s but I was only getting around 300mh/s. With the new krnlx miner I'm still only getting about 370Mh/s, which still seems pretty low. My miner also restarts with the watchdog reporting under utilization. My 1080 Tis are only running at about 60% and 1070s at 80-85% capacity. Can't figure out what's causing that.
EDIT: I added the '-i 25' flag to the command line and boosted core clock on the 1070s to +125 now I'm up at 480mh/s =)
