[boost::asio] link errors using boost 1.44.0 on 32-bit
Hi, I am mainly using boost::asio and I get a link error when I try to build my project on 32-bit release VC8.0 saying (The according 32-Bit libs are correctly included): error LNK2019: Verweis auf nicht aufgelöstes externes Symbol ""class boost::system::error_category const & __cdecl boost::system::system_category(void)" (?system_category@system@boost@@YAABVerror_category@12@XZ)" in Funktion ""class boost::system::error_category const & __cdecl boost::system::get_system_category(void)" (?get_system_category@system@boost@@YAABVerror_category@12@XZ)". error LNK2001: Nicht aufgelöstes externes Symbol ""class boost::system::error_category const & __cdecl boost::system::system_category(void)" (?system_category@system@boost@@YAABVerror_category@12@XZ)". However, compiling my project in 64-Bit release works just fine (according 64-bi libs included) and I don´t get these errors. Anybody knows what´s going on here? :-/ I searched the boost list for previous problems but none of the topics I found helped. Thank you in advance Samir

Boost.Asio depends on Boost.System library, and it seems that the linker can't find this lib.

thanks first of all. Yeah, that´s what the compiler says (well, actually it says that they are not defined not that the lib cannot be found) but what is the reason for it? All the 32bits libs are in the same directory. Just as all the 64bits libs are in the same directory and the system libs are definetly available in both directories (all possible configurations in there even the dlls...hehe, just to be sure) and the directory is correctly set in the project settings (for both), just that the 64-bit built works and the 32-bit one doesn´t. That is why I am stuck here. What could be the reason for it not finding the definitions in 32-bit but in 64-bit? That kind of doesn´t make sense. The system lib is definetly there.
