generate MAP-Elites archives error

[Hi-Ryan]

Hi, I have compiled the cullye_2015_nature repository and install depenencies for each. But when I generated the MAP-Elites, some error occurred. The error information is as follows:

dong@dong-pc:~/cully_2015_nature$ ./sferes2/build/default/exp/map_elites_hexapod/hexa_duty_text
debut run
sferes2 version: (const char*)"c1079efedd1d21b602e3ba02af37b6058ad5ddc3"
seed: 1540378784
Segmentation fault (core dumped)

So..can you give me some advice and tell me your compile environment such as the version of ODE and system version?
I run on Ubuntu 14.04 and the version of ODE is 0.13

Can you run the binary with gdb or valgrind and send us the trace corresponding to the segfault?

In addition, please note that we have a new version of this algorithm here: https://github.com/resibots/ite_v2

They are as follow:

It seems to be the same error as: resibots/robdyn#7

Unfortunately, we have no fix as we did not use this code (based on ODE) for years. The best option is to switch to ite_v2: https://github.com/resibots/ite_v2
