[aspectc-user] Problem with static member variable in template class

[Jens Schedel]

Hi,

i have an problem with the following piece of code:

================================================================================
#include <stdlib.h>
#include <stdint.h>

template<typename _OPMODE_T, uint16_t _GROUP> class Test {
    private:
        static _OPMODE_T opMode;

    public:
        void setOpMode(_OPMODE_T newMode);
};

template<typename _OPMODE_T, uint16_t _GROUP> void Test<_OPMODE_T, _GROUP>::setOpMode(_OPMODE_T newMode) {
// Error: error: invalid statement near token `='
    Test<_OPMODE_T, _GROUP>::opMode = newMode;

// Works
//  opMode = newMode;
}

template<typename _OPMODE_T, uint16_t _GROUP> _OPMODE_T Test<_OPMODE_T, _GROUP>::opMode = _OPMODE_T();

================================================================================


Compiling the code with: ag++ --real-instances results in the following error message:
error: invalid statement near token `='

As you see in the code, if i remove the type in front of opMode then ag++ stops complaining.
g++ has no problem with both variants.


I just wanted to reduce the code and removed the second template parameter and
figured out that the following pieces of code also compile without errors:

================================================================================
#include <stdlib.h>
#include <stdint.h>

template<typename _OPMODE_T> class Test {
    private:  
        static _OPMODE_T opMode;

    public:
        void setOpMode(_OPMODE_T newMode);
};

template<typename _OPMODE_T> void Test<_OPMODE_T>::setOpMode(_OPMODE_T newMode) {
    Test<_OPMODE_T>::opMode = newMode;
}

template<typename _OPMODE_T> _OPMODE_T Test<_OPMODE_T>::opMode = _OPMODE_T();

================================================================================
#include <stdlib.h>
#include <stdint.h>

template<uint16_t _GROUP> class Test {
    private:
        static uint16_t opMode;

    public:
        void setOpMode(uint16_t newMode);
};

template<uint16_t _GROUP> void Test<_GROUP>::setOpMode(uint16_t newMode) {
    Test<_GROUP>::opMode = newMode;
}

template<uint16_t _GROUP> uint16_t Test<_GROUP>::opMode;

================================================================================

Jens
