Compiling googletest for 32-bit target, embedded system

[DanBellmann]

Dear community members,
I want to compile googletest with a 32-bit compiler without changing the source code of googletest.
I use CMake to generate the build files. The compiler is not officialy supported by GoogleTest nor by CMake but still usable.
When executing make in the googletest-build directory I get errors like "long long" is nonstandard.

1.Question: Is there a 32-bit source code of googletest? The version has to be under 1.7.0. If not thats also okay!
2.Question: How do I avoid errors like these?

The GNU compiler gcc can do this with the option -m32, my compiler doesn't have such an option.

Thank you for your help and time!

@derekmauro what do you think it will be ok if I introduce change with stdint.h and replace things like long long to uint64_t?

It depends on the context. int64_t and long long do not have the same meaning.

int64_t is an alias type. long long is a built-in type.

Overload sets should to use long long, not int64_t, otherwise you risk defining overloads for the same underlying type twice, if aliases are setup that way.

This question is about GoogleTest <= 1.7.0, which is long out of date, and is also asking about an unsupported compiler. I'm not going to put any effort into supporting this use case.

Ah, ok. Better ask than be sorry :)
