    CodeXL 1.1.1157.0 profiles teapot, on debug exits pretty promptly



      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



      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: 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



      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!
