Hi! Now that zlib is part of the ToolKit, I would like to use it in my application too. When I link MFC and XTP statically, zlib functions like compress() uncompress() can easiely be called without any problem. But when linking MFC/XTP dynamically, I get an "error LNK2019: unresolved external symbol " Could somebody give me a hint on how to call the functions in the dll?

Hi
From dll exported only functions that marked with _XTP_EXT_CLASS
you can manually add some function in some .h file
_XTP_EXT_CLASS void ZLibCompress(..)
{ compress(...);
}

I have the same question but I cannot get Oleg's suggestion to work.
For the following function:
_XTP_EXT_CLASS int ZLibCompress( Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen){ return compress( dest, destLen, source, sourceLen);} I get the following:
error C2491: 'ZLibCompress' : definition of dllimport function not allowed |
