Hi,
I just started using botan library. I work on Windows XP SP2 OS. I have
compiled it under MS Visual C++ 2005 express to .lib file. I tried to run
some examples from botan-1.6.1\doc\examples catalgo, but in both
compilators, Borland C++ 6.0 and compilator mentioned before, i got linking
error. I followed instructions included in building.pdf, library and include
paths are set on catalog where is botan library file and \include\botan\
catalog with headers.
Example of error reports during compilation of hash.cpp from doc\examples\
under? Borland C++ 6 :
[C++ Warning] exceptn.h(22): W8058 Cannot create pre-compiled header:
initialized data in header
[Linker Error] Unresolved external
'Botan::LibraryInitializer::deinitialize()' referenced from
D:\DOKUMENTY\PROJEKT\BOTAN-1.6.1\DOC\EXAMPLES\HASH.OBJ
[Linker Error] Unresolved external 'Botan::Pipe::~Pipe()' referenced from
D:\DOKUMENTY\PROJEKT\BOTAN-1.6.1\DOC\EXAMPLES\HASH.OBJI have included file
of all errors for this compilation.
It seems compilator can't find library but path library is set. I don't
where else i can include botan library.
the rest of of linking errors almost the same for all examples
I made more tries to link programs with botan library. I hope it will help
more to solve my problem, i am really a bit hurry..
Error report during compilation underVisual C++ 2005 express:

I tried also to link botan library manualy by '#pragma comment(lib,
"libbotan.lib")' and i got errors:

LINK : fatal error LNK1104: cannot open file 'libbotan.lib'

I also made a try to link example hash.cpp in Borland C++ 6 with the same
'#pragma...' and got such error:
[Linker Error] 'D:\DOKUMENTY\PROJEKT\BOTAN-1.6.1\DOC\EXAMPLES\LIBBOTAN.LIB'
contains invalid OMF record, type 0x21 (possibly COFF)
Any idea what can be wrong?

Please help.
