Re: [Boost-users] [reflection] Compilation errors

30 Oct 2007

      Thanks guys, that solved this problem.

Still I'm having compilation errors. I'm trying to compile the following code:

#include "car.hpp"
#include 
#include 
#include 

int _tmain(int argc, _TCHAR* argv[])
{
	boost::extension::reflection car_reflection( "A Car!" );

	return 0;
}

The car class is separated into a header file. The errors have
something to do with the extension namespace. Here are some examples:

1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C3083:
'extension': the symbol to the left of a '::' must be a type
1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C2039:
'reflection' : is not a member of 'boost'
1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C2065:
'reflection' : undeclared identifier
1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C2275:
'car' : illegal use of this type as an expression
1>        c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\car.hpp(15) : see declaration of
'car'
1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C2275:
'std::string' : illegal use of this type as an expression
1>c:\documents and settings\i64044\my documents\visual studio
2005\projects\reflection\reflection\reflection.cpp(13) : error C3861:
'car_reflection': identifier not found

I think the real question is what header files and compiler symbols I
need to use to have the code compiling? The documentation is a little
spares on details.

Thanks,
Christian

I think his problem is that VC++ wizard automatically uses MB-charset for
wizard generated projects. I assume the lib itself uses LoadLibrary, which
expands dependent on the MB-Setting to either LoadLibraryA or LoadLibraryW.
Right-click on the project and select Properties; in the General tree node
set the Character Set to 'Not Set' instead of Multi-Byte... Than it should
be fine.

Hi there, I just pulled the latest reflection code from the sandbox
and tried to compile the example. But unfortunately there are
compilation errors.
For example:
c:\boost-sandbox\boost\extension\impl\library_impl.hpp(37)
: error
...
C2664: 'LoadLibraryW' : cannot convert parameter 1 from 'const char *'
to 'LPCWSTR'
Is the relection lib in a usable stage?
I don't know, but try to compile using the "Multi-Byte character set" flag
to get rid of the above error (assuming that you are using VC++).
If the library only supports multi-byte mode, it should probably
explicitly
use the Ansi varieties of the Win32 APIs.
