Hi,
Been interested in GPGPU for some time
Can see a use running robot mapping routines
Installed new GPU, battled with catalyst ended up back on stock drivers with updates
and then installed AMDAPP ran some examples,
Progressed to CodeXL
saw looked great tried! WOOPS! on debug
So been using pyOpenCL which suits me whilst learning
problem
when you load teapot, start debug CodeXL the GUI exits quickly,
when starting CodeXL from a terminal you do get a Segmentation Fault which is included below, The seg value varies a bit depending on what exactly you did to go into debug mode
dump file very small
Profiling Works!
Good news though profiling teapot works when run as a $user not when sudo or "root".
teapot runs from the command line as an application
Error Message and Dump File
Seg error codexl exit after attempting debug values vary depending on how you tried to enter debug
----------------------------------------------------------------------
./CodeXL
./CodeXL: line 41: 3113 Segmentation fault (core dumped)

CoreDump file
following log file open teapot, run debug:

Sometimes you see a caught qt exemption error illegal etc!

Cannot for the life of me get newer cat drivers working without stripping out kernel, sad to say AMD GPU's are not in the state anyone should expect in 2013, maybe in 1994 aceptable!
------------------
AMDAPP 2.8
CodeXL 1.1.1157.0
OpenGL seems to work fine
gcc 4.6
-----------------------------------------------------------------------------------------------------------------------------------------
ETC
OpenCL AMDAPP examples work,
CodeXL teapot works from terminal command line launch
python and pyOpenCL ok
---------------------------------------------------------------------------------------------------------------------------------------
Tried launching from different folders, inc /opt/AMD/CodeXL/bin/./CodeXL-bin same exits
Tried different $LD_Library_PATH, same or worse profiling stops working or issues with libGL.so
including adding /usr/lib/fglrx and /opt/AMD/codex/binl and /opt/AMDAPP/.....
tried hardcoding LD_LIBRARY_PATH in CodeXL, this seems to break things
---------------------------------------------------------------------------------------------------------------------------------------------
CodeXL Install Method
Original install was a rpm -> deb via "alien" , ubuntu software manager
Tried installing from a gz extract,
Tried overlay of gz file over the installed app folders
Tried alt location of extracted .gz file
Tried different users,
root or sudo seems to loose path to OpenGL as you launch profiler on "teapot", a graphics popup which promptly disappears & u never see the teapot,
profiling continues, not sure the full results are put to screen. when you select debug error popup about missing libGL.so.1, and despite all efforts to path to copy link cannot fix that one!
---------------------------------------------------------------------------------------------------------------------------------------
Libraries and Paths
Had some problems with AMDAPP with libOpenCL.so .... et al so ln -s to /usr'lib/libOpenCL.so
libOpenCL.so libOpenCL.so.1 libOpenCL.so.1.2 there seem to be lots of versions of the file and links not sure what is what there!
libGL.so libGL.so.1 libGL.so.1.2 there seem to be lots of versions of the file and links not sure what is what there!
AMDTTeaPot-bin runs from a terminal when run from the local folder, does not when invoked from file-manager click.
Tried using lib file in .../CodeXL/bin/spies .....CodeXL will not launch
have set the path /usr/lib/fglrx everywhere
-----------------------------------------------------------------------------------------------------------------------------------------
Thanks in advance!
