Re: [Yade-dev] can't launch yade

2010-11-26 Thread Giulia Macaro 
It worked! there was also a problem while it was compiling (qt4 was missing
in the scons.profile-default file, but then Chia added it).

Thank you very much!

 Oops, that was a typo on my part, it should have been just -x (without the
 slash), sorry.

 Excellent! Had you run with --debug, you would get backtrace, but this is
 good enough already! I think I fixed it in the latest revision (2573). Do
 bzr up and re-compile, it should work. In the unexpected case that it does
 not, run again in the debugger and inside (gdb) run yade with --debug (with
 or without -x, that does not make much difference).

 Explanation: since there is only one int division in OpenMPAccumulator
 constructor (by the constant CLS, cache line size, hardware-defined property
 of the CPU), it is apparently CLS that is not assigned correctly by
 sysconf(_SC_LEVEL1_DCACHE_LINESIZE) for your processor: it should be
 something like 32, 64, 128 but in your case it gives zero -- I guess that
 your processor model is too new for the system lib to know it (ubuntu 9.10
 you said, right?). I added a check for zero value there, in which case 64
 will be used as fallback.

 Cheers, Vaclav
