Cartesian Interface Solver segmentation fault

[lia2790]

Hi @liesrock @alaurenzi ,

I have updated all my Linux to ubuntu 20.04 from scratch and re-install all.

Now, I occur a segmentation fault in a point on the code which did not happen before. In particular, when I call

https://github.com/ADVRHumanoids/VariableImpedanceModulation/blob/3658daa515208d9f7dca29c30ba12593068d507c/utils/cartesio.cpp#L137

I also run the code with gdb and I obtain

Thread 3 "nrt_control" received signal SIGSEGV, Segmentation fault.

(gdb) 

How could I fix it?

thank you!

So, here I have wrongly installed libmatlogger2. I had two versions on my pc, the one installed automatically with xbot2 and one installed through the binaries where the last one installed the library inside the directory /usr/local/lib/ which actually originated that issue.

Then, thanks a lot to @liesrock we fixed all removing the version installed through the binaries and everything worked as the same.

Thank you again.

Solved.
