Hello,
I am stuck and need some help. I am taking the uWave embedded code that is
currently being compiled with Tornado 2.0 and 'porting' the code so that it
works with the new Tornado 2.2 (gcc 2.96 I believe) compiler (c++ code),
which is apparently more ANSI C++ compliant.
I am getting an error while trying to compile one of my project. The
problem code and the error message are below:
Code:
Raw_preproc.h:
CComQIPtr<IDspCaptureData> pIDspCaptureData;
DSPAlgsTypes.h:
template <class T, const IID* piid = 0>
class CComQIPtr
{....
where IID is:
#define IID long
Error Message:
M:\\ThomasAn_jedi_uWaveEASInstrPrivate\\igxlwc\\Platform\\Inc\\drivers\\Raw_preproc.h:55:
could not convert template argument `0' to `const long int *'
M:\\ThomasAn_jedi_uWaveEASInstrPrivate\\igxlwc\\Platform\\Inc\\drivers\\Raw_preproc.h:55:
ANSI C++ forbids declaration `pIDspCaptureData' with no type
I've tried a number of things but I can't get the above code to compile. I
have also modified DSPAlgsTypes.h to the following:
extern const IID tempNull = 0;
template <class T, const IID* piid = &tempNull>
class CComQIPtr
{...
The individual files compile but it won't link. Also, a number of other
projects (that reference DSPAlgsTypes.h) are broken. I've also tried
casting in DSPAlgsTypes.h to the following:
template <class T, const IID* piid = static_cast<const IID*>(0)>
and
template <class T, const IID* piid =(long *) 0>
and I get the following error message:
M:\\ThomasAn_jedi_uWaveEASInstrPrivate\\igxlwc\\Platform\\Inc\\drivers\\Raw_preproc.h:55:
`0' is not a valid template argument
M:\\ThomasAn_jedi_uWaveEASInstrPrivate\\igxlwc\\Platform\\Inc\\drivers\\Raw_preproc.h:55:
it must be the address of an object with external linkage
Any suggestions that you can offer would be most helpful.
Best Regards,
Anish
