[LINUX MINING] bfgminer segmentation fault

[audricd]

hello,

Id like some help setting up bfgminer on linux, more precisely OpenSuse 13.1.

Ive been following this guide:
http://wiki.tiker.net/OpenCLHowTo

And expect a few minor changes because its slightly outdated (pretty much download links and versions numbers) i did everything it tells.

yet whenever i run bfgminer (even with the -S opencl:auto tag) or guiminer i get a segmentation fault.

OpenCL seems to be installed correctly, because prior to this, the error message i had was from guiminer saying i had no opencl devices in an alert window. now i dont even get to that.

i ran aticonfig --initial, blacklisted the opensource radeon driver and this is my fglrxinfo output:

audric@linux-soqy:~/poclbm> fglrxinfo
display: :0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon HD 5700 Series
OpenGL version string: 4.4.12874 Compatibility Profile Context 14.10.1006

any help please?

You probably won't get too much help here in the beginner section, try asking a mod to move this thread to the "Mining Support" section (or post it there yourself, now that you have a high enough activity).

Just a heads up that a segmentation fault could very likely be a lack of RAM.

hello all, and thanks for the replies.

I come with updates.

So apparently the segmentation fault was due to the fact my icds were misplaced. so i added them (it seems) by taking a shot in the dark doing files likes this in opt/vendors/OpenCL

filename:
amdocl32.icd

content:
/opt/amd-opencl-icd-VERSION.MINOR/lib/libamdocl32.so


i have done this for amdocl64.icd, amdoclcl64.icd, aticalc.icd, aticaldd.icd, and aticalrt.icd. All the icds i could make of the libs provided by the amd sdk.

also, two shortcuts were automatically made by installing the sdk:
libamdocl64.so
libaticalcl.so

they both point to /opt/amd-opencl-icd-VERSION.MINOR/lib/

when i did that, bfgminer told me it couldnt find/read phatk121016.cl, so i made it for him by downloading and adding it from the source:
https://github.com/fcicq/cgminer/blob/master/phatk121016.cl
into my bfgminer folder. it worked.

after that, unfortunately, i have yet another error, this is the new and latest output:

it seems its definitely a step forward as the gpu appears to be detected

also I forgot to mention we are talking about a ati 5780 1gig, the rest of the rig is a amd phenom quad 3ghz, 4gigs of ram ddr2.

im making progress but im stuck again.

Good to know; I thought the requirement had been reduced from 5 posts in the beginner section to 1, not removed entirely. Thanks for the info!
