twain.h with C++Builder

[efrenba]

Hi there,

When I try to compile a project under C++ Builder6 with twain.h the compiler shows me the error:

[C++ Fatal Error] twain.h(130): F1003 Error directive: Unrecognized compiler

I read in the C++Builder’s help that __BORLANDC__ is a global identifier, not __BORLAND__.
I tried changing the identifier __BORLAND__ for __BORLANDC__ but the errors increased:

[C++ Error] twain.h(1863): E2257 , expected
[C++ Error] twain.h(1864): E2238 Multiple declaration for ‘huge’
[C++ Error] twain.h(1863): E2344 Earlier declaration of ‘huge’

[C++ Warning] _epilog.h(38 ): W8059 Structure packing size has changed

I downloaded the twain19.h and with it I could compile the project.

Is there a solution that allows me to use twain.h with C++Builder6?

thanks in advance,
Efren

I don’t know if you tried this,　but type this BEFORE including twain.h:

#undef __BORLANDC__

#define __BORLAND__

Otherwise, modify this line in twain.h

#else

#error Unrecognized compiler

to

#else

#define TWH_CMP_BORLAND

#define TWH_32BIT

Note this breaks the compiler portability of twain.h

Hope that helps.
