Quote from: eck on May 01, 2011, 04:41:50 PM Having some trouble compiling this on Ubuntu 11.04 x64: Code: jwasm -DX64=1 -10 -elf64 -zcw -c -Fosha256sse.o sha256sse.asm JWasm v2.05, Mar 2 2011, Masm-compatible assembler. Portions Copyright (c) 1992-2002 Sybase, Inc. All Rights Reserved. Source code is available under the Sybase Open Watcom Public License. sha256sse.asm(48) : Error A2091: Language type must be specified sha256sse.asm(314) : Error A2142: Unmatched block nesting: CalcSha256Sse sha256sse.asm: 316 lines, 1 passes, 0 ms, 0 warnings, 2 errors make: *** [sha256sse.o] Error 1 I checked the sha256sse.asm file and found that a language type was declared on x86, but not on x64. I removed the if statement, and did the same on the other ASM file, which allows it to compile but then I get "error 80004001" if I try to use it. Obviously the language type isn't declared on x64 for a reason, but I'm just not certain what it should be on x64 (since it obviously has to be something). This also happened with the latest version of JWASM - I'm using the older one since that's what most others here are using though. Thanks in advance! On another member's advice, I simplified it from IF X64 ELSE OPTION LANGUAGE: C .XMM ENDIF to this OPTION LANGUAGE: C .XMM It compiled OK, but now I get a segmentation fault every time I try to run it (I can run the program, but as soon as I try to actually connect to a server and mine bitcoins, I get the seg fault)

Quote from: kr105 on May 23, 2011, 05:26:24 AM Hey ufasoft, I compiled your miner on ubuntu x64 and I get a segfault: Code: root@ts3:~/ufasoft_bitcoin-miner-0.10# ./bitcoin-miner -g yes -o http://deepbit.net:8332 -v -u xxxxxxxx -p yyyyyyyy bitcoin-miner 0.10 Copyright (c) 2011 Ufasoft http://ufasoft.com/open/bitcoin Mining for http://deepbit.net:8332 1 threads Using SSE2 Switching to http://j2.deepbit.net:8332 Segmentation fault (core dumped) root@ts3:~/ufasoft_bitcoin-miner-0.10# Here is the coredump, hope it helps. I just had the same problem this morning. I recompiled everything for Ubuntu 11 (Linux Mint, actually, which is basically Ubuntu under the hood) 64-bit. Ideas? Matthew P.S. It took me much less time to compile it this time, since I already had a recent version of GCC, etc. Seems that I had to do a lot less manual compiling this time around.

I apparently get a lot of Linux geek cred -- I compiled it to work on Ubuntu 10.04 (32-bit). Once you get used to compiling source, it's not that big of a deal. You just have to look at the "install" file for the instructions, etc. Often, you have to go 1 level deeper and get a prerequisite -- compile that -- then come back to where you left off, and continue. Eventually, you're able to compile the program you set out to compile And it gives you a great sense of accomplishment, I must say. I speak from personal experience here Anyhow, I'm sure Linux gives you a bit more power, since you can customize everything and can easily turn off things you don't need. I'm wondering now if 64-bit would give me any more power -- I'm upgrading my PC & vid card (whole new system, actually) and I plan on installing Mint 10 or Mint 11 -- they're supposed to be better than Ubuntu (both are based on Ubuntu). Plus it's an Irish distribution, and I have Irish heritage Anyhow, I might go with the 64-bit install. I'll have to recompile everything, but maybe I'll make a list or guide this time around, and I can post it on somewhere like this forum. Matthew

That SAPPHIRE 100297L Radeon HD 5830 (The link to NewEgg, posted above) does it have a Linux driver, specifically Ubuntu? Thanks.

I experimented with poclbm settings today -- python poclbm.py -d 0 -r 5 --user USERNAME --pass PASSWORD -w 64 -f 10 -o http://mining.bitcoin.cz -p 8332 I haven't messed with the "a" setting yet. I'm now getting 7.8 to 8.0 MHash/s between one instance of poclbm (1 thread) and one instance of bitcoin-miner (running in 2 threads) There's a bit of lag on my desktop now, so the GPU seems to be doing something. How can I check what version of NVidia driver I'm using? Also, how do I run poclbm on the GPU but not the CPU? Is that even possible? Thanks, Matthew

I'd like to spend no more than $110 or so on a video card. What's the best card at that price range?

Now ufasoft's bitcoin-miner should be doing GPU as well as CPU mining since I have it set to "-g yes". So you think that 5.5 MHash/s is CPU-only mining? I compiled and tried poclbm (Python) today, but I only got 3.2 MHash/s when I launched it twice. It was clearly using 100% of both CPU cores. I suppose Mhash/s is something that can be compared across the different programs -- they don't have different ways of computing the speed, do they? I wonder why ufasoft's miner isn't using my graphics card.

Hi everyone -- just joined the Bitcoin universe. I'm a Linux guy; I just successfully built the source for Linux (took a few hours to get all the pieces in place!) I don't think I'm getting any GPU work done. I have a nVidia GeForce 9500GT 1 GB card -- pretty fast for 3D actually (for me, I mean. Not by today's standards!), but I don't know if it's supported by most miners. Does anyone know which cards are supported? I'm getting 5.4 - 5.5 MHash/s using 2 threads. The most I ever get is 5.61 MHash/s I have a Core2Duo 2.4 GHz CPU. My machine is actually pretty old -- 2 years! I'm going to get a new one in a month or two. Nice to meet you all! Matthew
