CGMiner 3.1.0 built under linux, then segfault on execution

[ChristianRiesen]

Hello everyone. I've decided to jump head first into the boiling pot and got stuck at a rather inconvenient location.

I've tried building the miner now about a dozen different ways, no dice. The endresult is always this, if I get it to configure and compile at all that is:

Code:

# ./cgminer --benchmark
 [2013-05-11 08:37:38] Started cgminer 3.1.0Segmentation fault (core dumped)
#

I read in the official thread about adding a stacktrace with gdb cgminer core and here it is:

Code:

I went a bit further and tried installing the latest drivers.

Removed the drivers I had in before with this:
aptitude purge fglrx-updates fglrx-amdcccle-updates fglrx-updates-dev

Got the drivers here:
http://www2.ati.com/drivers/linux/amd-catalyst-13.4-linux-x86.x86_64.zip

It complained about not having X so I installed it with this:
aptitude install x11-common xserver-xorg-core

Installed it, and then rebooted.

Configure fails with this:
OpenCL...............: NOT FOUND. GPU mining support DISABLED

aticonfig fails with this:
# aticonfig -lsa
aticonfig: error while loading shared libraries: libXrandr.so.2: cannot open shared object file: No such file or directory

Fixed it with aptitude install libxrandr2. Output now is:

# aticonfig --lsa
* 0. 01:00.0 AMD Radeon HD 7900 Series

* - Default adapter

configure still fails...

[ChristianRiesen]

So it works, sort of, still needs a bit of testing, but here is how I got it to do as it should in the end:

• Installed the ati driver again.
• Killed the cgminer dir and redid that from scratch.
• Copied ADL files to cgminer.
• Copied the files from the APP sdk to the /usr/include and /usr/lib as the GPU-README of cgminer says, and of course run ldconfig
• rebooted
• ran configure on the cgminer, then make, both went through without a hitch
• Now it works...

I will retry at a later stage to see if I can reproduce the success.

Hi Christian,

Could you eventually reproduce this error and do you have a resolution for this? I experience the same message with OpenSuSE 12.2 and CGminer 3.1.0.

aticonfig --lsa recognizes my two graphi9cs cards OK, configure and make install do also work flawlessly.

Thanks

Hi

I made mistakes that far back that resulted in a rather ugly binary. I have since refined the process and can reproduce a stable version with working ADL in it on 3 different machines. I'm working on a tutorial for that as of now

[rafi365]

I've had the same problem. Hope you will make tutorial asap.
Thanks in advance.

Any reason that you're trying to build your own binary vs just downloading the precompiled linux build from the author?

I have a pretty thorough linux guide here (part 2), if it helps:

http://www.cryptobadger.com/build-your-own-litecoin-mining-rig/

Although I don't compile cgminer from source in my guide; I just use ckolivas's build.

I've used this but I get Segmentation fault when I try to run cgminer.  This has been a problem with absolutely every guide I've used.
