[Qt-interest] Re :: Error in OpenMp with QThread

[satyanarayana reddy]

hi,
 I am running a Qt application in which I have used openMP to parallelise a
for loop. Its working fine with both windows and Ubuntu..

Now I need to show and update the progress of the loop calculation. So I am
using QThread. and keeping the calculation part in run() function of
QThread. Its working fine with Ubuntu but in WinXp its giving a problem.
Help me with this

The application is crashing at this line of code::
omp_set_num_threads (2);

Its giving the following error::


Program received signal SIGSEGV, Segmentation fault.
[Switching to thread 2672.0x940]
