[cgma-dev] Large OCC subtraction time

[Jiangtao Hu]

Ok, now I also updated and make installed Lasso, but meshkit still fails to build. Any suggestions.

Hi, 

I just tried to build meshkit, with the following configure:

./configure --enable-debug --with-itaps=/mnt/disk2b/jhu/ddriv

it failed on compiling EdgeMesher

I've updated cgm, moab and meshkit, and built, installed cgm and moab, did I left something out?

Thanks.

In my case of using OCC geometry, attribute updating and removing time take too long.
It takes more than import/exporting time of the geometry.
