I am also encountering the segmentation fault error, while clicking the geometry tab in flair. I came across this solution and subsequently, I downloaded and replaced the ‘d3layer.cc’ file in viewer sub-directory. But after issuing make command, I get a number of errors (screenshot attached). I am running Ubuntu 20.04 in VM. Is there any specific package that I need to install?
actually the patch that I posted is not compatible anymore with the last release of FLAIR where a lot of things have changed (and improved) under the hood.
In any case in version >= 3.1-3 my patch is fully integrated already.
A few things to check/try:
Which version of FLAIR did you use?
When you define your virtual machine, how many virtual cores do you allow it to use. In general I would suggest to use the maximum number you can.
Try to build the geoeditor with the following command make THREAD=no and try to relaunch FLAIR’s geoeditor. Does it still crash?
