unity_fixture.h macros???, GCC differences to (VC++ and Softune)

Hello,

Thank you for an excellent book, I am now reading and testing at the same time.

I am using VC++ 2008 Express for testing

the CppUTest works fine! but when I am trying the Unity I get compile errors both on my target (softune compiler for a Fujitsu mcu) and in VC++

I have found out that GCC accepts a function declaration just before a call to the declared function inside another function, see below:
I have manually done the macro prepossessing that are defined in unity_fixture.h, am I missing something here?

TEST_GROUP_RUNNER(LedDriver)
{
// RUN_TEST_CASE(LedDriver, LedsOffAfterCreate); 
   void TEST_LedDriver_LedsOffAfterCreate_run(); 
   TEST_LedDriver_LedsOffAfterCreate_run();

// RUN_TEST_CASE(LedDriver, TurnOnLedOne); 
   void TEST_LedDriver_TurnOnLedOne_run(); // this is row 30 that the compiler reports an error for, see below 
   TEST_LedDriver_TurnOnLedOne_run();
}

—-—-- compile error in VC++ 2008 express --—-
code/unity/LedDriver/LedDriverTestRunner.c(30) : error C2143: syntax error : missing ’;’ before ‘type’
-—-—-—-—-—-—-—-—-—-—-—-

To get this to work in VC++ and Softune, I had to move out the 2 function declarations above the function.

Perhaps I have missed to set some compiler switches to allow these declarations or what am I doing wrong?

Kind regards

Hello again!

Now I have come up with a fix that is working in VC++ and Softune but NOT in GCC :(

I have changed the following in unity_fixture.h:

-------- old macro -----
#define RUN_TEST_CASE(group, name) \
        DECLARE_TEST_CASE(group, name);\
    TEST_##group##_##name##_run();

//Call this from main
#define RUN_TEST_GROUP(group)\
    void TEST_##group##_GROUP_RUNNER();\
    TEST_##group##_GROUP_RUNNER();
------ end of old macro ----------

----- new macro ----------------
#define RUN_TEST_CASE(group, name) \
    { DECLARE_TEST_CASE(group, name); } \
    TEST_##group##_##name##_run()

//Call this from main
#define RUN_TEST_GROUP(group)\
    { void TEST_##group##_GROUP_RUNNER(); } \
    TEST_##group##_GROUP_RUNNER()
-------- end of new macro -------------

Kind regards
Anders

That is odd. Though the VS compilers are converging on the standard. VS2010 might be more compatible.

Hi James,

Big fan!

I’m trying to port the examples supplied in the Unity distribution to use your unity_fixture from extras in Visual Studio 2010 Professional and I’m getting the same error. :/

The changes above fixed my problem as well.

Any suggestions on how to make this work across the platforms? I’d be willing to submit a pull request to Unity, but I’m not sure the best way to solve the incompatibility. To be honest I don’t think I understand the incompatibility :)

Thanks in advance for your thoughts / advice!
