Hello JamesYou may be able to make your code work with cmocka in both environments using various pre-processor controls. Here is an article that includes testing problems and the the preprocessor controls that can be used to solve those problems. I am not sure if these really apply to both your issues or not. It probably could help with the typedef problem. I consider the pre-processor the last tool to use when getting code into a unit test harness. But sometimes it is the only option where you do not need to change the code under test.
Something we did with CppUTest, another open source test harness I contribute to, is to separate system dependent code. The makefile would choose the appropriate platform files to build depending on the platform. We have a PlatformSpecific.cpp file that would provide system dependent functions.

Hey Andreas, a couple of comments. The background for this is that I amrunning tests using both GCC (for CI) as well as using an embeddedcompiler compiling to a simulator target (for the sake of developers using the same IDE as primary development). This may not be within the scope ofyour development, but may be useful to other users, portability wise.CMocka seems to make some assumptions at compile time, more or less thatthe target environment is Unix-like/GCC compiled or Windows-like/VS compiled. This breaks compilation for me in a couple ways.1: My embedded compiler defines some, but not all of the exception signalsin the array in cmocka.c:281. This is not new to cMocka 1.0, for now Ihave added in a compiler flag to change the definition of this array. It would be nice to have an option to be blind of exceptions at compile time(sort of like 'handle_exceptions', but at compile time rather than runtime). 2: I had some problems with the 'uintptr_t' logic in cmocka.h:101. Probably nothing unique about that type, except that it was defined inanother header file. Unfortunately I have no way of "informing" cmocka.habout my other 'stdint.h' file, and a re-def of uintptr_t makes thecompiler sad. Again, this is not new to cMocka 1.0. It might be nice to have some sort of user defined includes? Something like the following atthe top of the headers?: #ifdef _CMOCKA_USER_INCLUDES #include "cmocka_user_includes.h" #endif3. This one actually is new to cMocka 1.0. My compiler defines time.h, but does not define the struct 'timespec'. Similar to my exceptions comment,there is some handling for targets not supporting test timing, howeverthis is not completely transparent at compile time. I could fill in thedefinition of timespec, however I dont really have any way of lettingcmocka.c know where to find it (modifying my compiler's time.h is not an option). It would be nice to have a compiler flag to completely excludethe timing component.Up to now I've just fixed items 1 and 2 in little hacks of the file thatare "good enough" for my compiler, though likely not very useful orportable. It would be nice to see these supported in mainline development,if you have any ideas.Please let me know if you have any questions, would like these filed as tickets for addressing later, or have any changes you would like me to tryout.
