Only version of these three i could try is the ATI HD5xxx. First thing i got was an error after the kernels were build successful. All needed info for analysis inside attached package. Guess you did not have ML and Lion in mind when building this app.
Joe Fox:
Hi Urs, thanks for the debug info. I'll analyze and make adjustments.
Urs Echternacht:
@JoeFox : TBar has tested also in the meantime and he couldn't run your ati app either. Neither on Yosemite or ML. (EDIT: retest with correct commandline call was successful on Yosemite.)
Awaiting your adjusted builds. If you need more help, some other tests, just ask.
Joe Fox:
Hi Urs,
Attached are updated builds. The ATI one is now running correctly on an old macbook pro that I found which exhibited the crash you saw.
Thanks
-Joe

Joe, the second app version of your seti_boinc-hd5xxx fails similarly to the first one on my Mac mini 5.2 (mid 2011 with discrete ATI Radeon HD 6630M onboard) with ML. Again i have attached the debug output and additional a comparison of your weak bound symbols and lazy bound symbols to one of my latest trys to build this app for the Mac. Mine is missing some signals, but has acceptable performance, while yours works correct but inaccepatble slow on Mavericks and Yosemite. If you check the comparison (done with OS X tool dyldinfo) you will find that weak and lazy symbols are somehow switched in the two builds. Also it still shows that your build is using "__DATA __la_symbol_ptr 0x1002DB0F8 0x00DF libSystem ___sincos_stret", which apparently is not present before OS X 10.9 (Mavericks). This makes it impossible to run your app on older OS X versions (10.7.4 (Lion) and 10.8.5 (Mountain Lion)).
