Segmentation fault of dcemakeversion while ./waf build

[Emilín Amy Hao Jingjing]

Hello Everyone and Experts,

I met a problem haunted for very long time. It occurs segmentation fault while I am trying to use ./waf to build the directory ~/ns3-dce-workspace/bake-test/source/ns-3-dce. It seems the trouble from dcemakeversion, but I don't know what to do to help such situation to pass build and to run examples.

Thank you in advance of solving this problem as quick as possible.

Best,

Emilin Amy
