openMP issue with Poisson Reconstruction

[jonathanbyrn]

Hi,
I am trying to use the poisson reconstruction plugin but every time I try to apply it I get this error:
CloudCompare: symbol lookup error: /usr/local/CloudCompare/plugins/libQPOISSON_RECON_PLUGIN.so: undefined symbol: omp_get_num_procs

extensive googling seems to indicate that this is a compile time requirement, rather than something missing at runtime but when I run cmake everything builds perfectly.
I am using the latest version on github and running it on ubuntu 14.04, the other plugins I build like the pcl library are running correctly. Any help would be greatly appreciated

This error means that your compiler doesn't support OpenMP (which is strange for gcc/ubuntu but who knows...).

You have to deactivate the 'POISSON_RECON_WITH_OPEN_MP' option in CMake.

That confused me aswell, if it compiles correctly with gnu and the -fopenmp flag then surely it should find the methods at runtime. Anyways I rebuilt it without openMP and now it is working correctly. Thanks again for your help and I will post on the github bug tracker in future.
