Hi all.

I've got an problem with C++ and JCom.

I want to compile an JCom - cpp file with MinGW C/C++ compiler.
In the first step of compiling i will get an *.obj file which will be after linking an *.dll file

My Problem is a failure by including the headerfiles.
here the commandlineerrors.

..\jcom\test>C

mingw\bin\g++ -IC

j2sdk1.4.2_07\include\ IUnknown.cpp
In file included from atlbase.h:69,
from IUnknown.cpp:9:
atlconv.h: In function `OLECHAR* A2WBSTR(const CHAR*, int)':
atlconv.h:199: warning: passing NULL used for non-pointer converting 6 of `int MultiByteToWideChar(UINT, DWORD, const CHAR*, int, WCHAR*, int)'
In file included from IUnknown.cpp:9:
atlbase.h: At global scope:
atlbase.h:73: warning: malformed '#pragma pack(push[, id], <n>

' - ignored
atlbase.h:79: warning: `selectany' attribute directive ignored
....
....

Maybe anyone could help me?
Thanks
Peter

those messages are no errors, only warnings. I think you can ignore them

hi.

thanks for your answer, and i'm sorry for posting a discarched code.
the warnings are repaired and the main errors (which i already meant last time) are the following:

filecode:
____________________________________
template <class T, const IID* piid = &__uuidof(T)>
____________________________________

the resultant errorcode:
____________________________________
In file included from IUnknown.cpp:9:
atlbase.h:568: error: expected primary-expression before ')' token
atlbase.h:568: error: there are no arguments to `__uuidof' that depend on a temp
late parameter, so a declaration of `__uuidof' must be available
atlbase.h:568: error: (if you use `-fpermissive', G++ will accept your code, but
allowing the use of an undeclared name is deprecated)
atlbase.h: In member function `HRESULT ATL::CComQIPtr<T, piid>::CoCreateInstance
(const CLSID&, IUnknown*, DWORD)':

Thanks Peter

it could be possible that your gcc version does not accept those template definitions, perhaps 0xdeadbeef or someone else can help you with it, I'm not very fit in templates and gcc
