Thanks… I got this working on Centos 7, here’s what I did…

As advised, I made width and height public in ./zxing/LuminanceSource.h

As Centos 7 (and Red Hat) lack the ec_curve cipher in openssl, I applied this patch to src/key.c

http://pastebin.com/raw/iFYJsgus

Then I manually replaced all remaining occurrences of

EC_KEY_new_by_curve_name(NID_secp256k1);

with

EC_KEY_new_by_curve_name_NID_secp256k1();

Surely an ugly hack, but the wallet is now syncing…

Note: I cloned zxing from https://github.com/glassechidna/zxing-cpp.git into the Feathercoin subdir then
cd src/qt
ln -s …/…/zxing-cpp/core/src/zxing zxing

I am interested in building a Point Of Sale ledger on a blockchain.

I have 25+ years experience in wholesale/retail databases.

I am willing to build each POS a full node with a decent GPU.

Have been watching Syscoin, but they seem to be suffering from feature bloat and regular hard forks. I’m a keep it simple (and efficient) kind of guy.

The ledger would have accurate inventory and sales data tracked by FTC address. A ‘warehouse’ would distribute and restock via small FTC transactions. Product sales would also be processed by a small transaction. Miners could profit by prioritizing these transactions.

Roughly 1000-2000 transactions per day for my current pool of 30 POS systems. Average transaction size is 80 bytes.

Any interest here?

Portions of our code would require NDA (I didn’t write it).

Edit: Mirrax, if you steal this concept, I’ll hate you forever. Patent it if you will, I want half. Software patents (IMHO) suppress progress and the evolution of innovation.

@aciddude

I’ve been running various wallets and patches on Centos 7 for quite a while now and this is a great example that can be applied to many many coins.

Thanks for the detailed step by step, this will simplify many wallet upgrades for me!

THANKS!

Back to mining FTC…

@mirrax Just being sarcastic, it’s in our blood here in Upstate NY. I’m also one of the ‘nice guys’. Stay calm and mine on! ;)

Holy crap, 5k stream processors? Make sure you post your hash rate, that’s a monster.

PS: My condolences on the dog, lost the wife 6 weeks ago and the dog keeps me going. Remember we’re pioneers in mining.

I am also having issues compiling on linux. After finally getting zxing installed, I am now getting several of these errors.

./zxing/LuminanceSource.h:31:13: error: ‘const int zxing::LuminanceSource::width’ is private

Advice? Guidance? Beer?

@AmDD Technically the GPU would only have to mine enough FTC to support it’s own transaction flow, so a lower end card would possibly work. Another option would be to use a small SHA256 ASIC miner and auto-exchange to FTC.

Good information. Thanks everyone!

I’ve got a dev box at home with 14.04 LTS installed on it. Would getting this working on that help at all? If so, what version should I try?

I managed to get my primary wallet running on Centos 7 but that was a totally different scenario.

Just trying to help out, the wife passed 6 weeks ago and I’m trying to keep busy. I’ve been pretty active with Syscoin lately so a lot of this is pretty fresh to me.

I’d go 7870.

I’m getting these #s now:

HD 6950 - 80 kHash/s
HD 7950 - 380 kHash/s

I’d estimate HD 7870 at around 200k, but I could be completely wrong. I was considering buying one myself just to find out.

Thanks… ;)
