Can not compile when using std_msgs/Int8MultiArray
Hi, I'm trying to use an array topic but I get the following error when compiling :

There seems to be a problem with MultiArrayLayout.h causing the compilation of all arrays topics to fail. I've tried to modifiy it but I wasn't able to find the fix. Maybe it's a cpp compiler version issue.
I'm going to use another solution for now but it would be great if anyone knows how to fix this.

I am facing the same issue. Did somebody find a solution for how to use any MultiArrays based on MultiArrayLayout.h in rosserial with ESP-IDF?
