All,
I am trying to compile KiCad with the latest compilers and libraries from
Apple. I am getting an error in common/tool/tool_manager.cpp at line 180.
[ 86%] Building CXX object common/CMakeFiles/common.dir/tool/tool_manager.cpp.o

note:

What is is complaining about is the std:stack stateStack is taking a template
parameter TOOL_STATE. However, at this point we are still in the definition of
TOOL_STATE so that TOOL_STATE is an incomplete type so the sizeof in the header
isn’t working.
Looking at the code, I don’t see a simple way to fix it. Apple’s latest library
is compliant to the C++ standard so I suspect the next version of g++ will also
complain about this usage. Any thoughts? Maybe use a pointer to the state in
the stack and then use new/copy/delete.
