Compilation Problems

[Eduardo Hernández Guerra]

I have been using and gtest and gmock for testing embeded SW for a
while, using Green Hills C/C++ compiler (v5). I only had to do minor
modifications to the code to make work, mostly related to OS calls.

However when I try to use the ElementsAreArray() matcher, I get the
following compilation errors:

1>gmock-1.6.0\Include\gmock/gmock-matchers.h(2533): error #276: name
1> followed by "::" must be a class or namespace name

I've tried to work around these but nothing seems to work. Can you
help?

If I had to guess, the matcher expects a value_type typedef in the class  internal::StlContainerView<RawContainer>::type.

Eduardo -

The ElementsAre and ElementsAreArray match containers, mainly STL-like ones. They can match a container passed in as tuple(pointer, size) as described in http://code.google.com/p/googlemock/wiki/CheatSheet#Container_Matchers, but you are apparently not passing in the size.

It's hard to give you concrete advice without seeing your code, but in general, the size must be passed into the function together with the pointer and you should use the Args selector to give ElementsAre the right set of arguments to match.

What changes did you have to make in order to get GTest to build under Green Hills?
