elements of array have incomplete type

["Charles L. Farbstein" <charlie.farbstein@xxxxxxxxx>]

I am getting the following error.  I do not understand why.

charlie: 18> g++ -c test.cpp
test.cpp:10: error: elements of array `A::MTWSCommands A::X::lvcCommands
[2]' have incomplete type
test.cpp:10: error: storage size of `A::X::lvcCommands' isn't known
test.cpp:7: error: storage size of `A::X::lvcCommands' isn't known
