Hi there,

I've tried this a few times now on mint and ubuntu (various versons18,20,22 etc) and never got it working.
If any one can help me get this working i'd love to give it a try.
I'm pretty dumb, so a full step by step guide is needed...

Thanks
J

It transpires that j0nn9 left us “an exercise for the reader” in the GapMiner rev5.1 code, just here:
https://github.com/gapcoin/GapMiner/blob/2f66e908e52dab503de77835f31ac1603b1c23fc/src/HybridSieve.cpp#L398

Code:
sieve_t min_len     = log_str(mpz_get_d(mpz_start)) * d_difficulty;

should read

Code:
sieve_t min_len     = log(mpz_get_d(mpz_start)) * d_difficulty;

The difference was causing GPU builds of the GapMiner rev 5.1 to segfault (on both AMD and nVidia).

I fixed that (along with some other compilation-blockers) and re-worked the Makefile so that it can be used to create either CPU or GPU miners (AMD and nVidia) without having to be edited to do so.

I've cloned gapcoin-project's GapMiner repos here https://github.com/gjhiggins/GapMiner, check out the README for details of how to compile gapminer and gpugapminer on Linux. When I'm satisfied that it works for people, I'll raise a PR on the gapcoin-project GapMiner repos and update that.

Thanks to benxy031 for providing that nVidia-compatible fermat.cl code, I've included it in the gpu subdirectory as fermatnv.cl and adjusted the miner code to load whichever OpenCL source file is compatible with the detected platform.

Cheers

Graham

What problem are you experiencing? Are you not getting a successful compilation? Does it compile okay but won't run? Does it run but can't connect to client?

Cheers

Hi Everyone,

I'm new to Gapcoin.
I have my wallet synced but i'm not sure which miner i should use (i found different version)
Does anyone would post here the link to the correct updated version.

Another question is : Is it pointless to mine on CPU or not. I couldn't find really how fast i'm "hashing" on the miners i found.

Thanks.

Hey,

sorry for the delay.

The Gapcoin is definitely CPU friendly.
Mining from the wallet is a good way to get the best hashrate. A 3900x cpu will give you ~3M PPS (mining at shift 25-32). A rx580 gpu will give you ~1.6M PPS (mining at shift 64). It's all an 'efficience' question.
If you're more interested with the Maths behind and the CRT miner (shift 64-1024), feel free to come on Discord ! ((:
I'll give you more information about the different ways to mine the Gapcoin, and the related places, with pleasure.

Also see the Website made by Mr. Higgins :

Cheers !

Hi,

Thank you for these info.

Seems like the only recommended pool is a desert.
Is it better to mine form the wallet solo ?

I'm on the discord under the same name.
