Hi!
I am building a custom module. The build is compiling fine for px4_sitl (running
make px4_sitl_default).
When I build for cubepilot_cubeorangeplus flight board(running make cubepilot_cubeorangeplus_default), I encounter the following error while I use #include <iostream> in .h header files -
FAILED: src/a.cpp.obj
