I'am using log4cxx with g++ for about one and a half year, without any problema at all...
But now I have to develop something in Windows, and I must use VS2008... I read a lot of messages in the list, and I get that I have to build the library as a static library, but I do think I am not doing it the proper way... Two steps: 1) I build the library itself... I select the static library option, /MTd and I do set the preprocessor to these values: OBS: apr, apr_util and xml projects use the /MDd option... I choosed not to change that at first (at least, no one said it should be done). And I do guess that is not important at all... OBS2: note that with VS2008 at least, it is not possible to specify another libraries that lib4cxx.lib has dependencies... well, the compiler does not return any error messages anyway... it does build the lib right away... ORIGINAL VALUES: _DEBUG _USRDLL DLL_EXPORTS LOG4CXX APR_DECLARE_STATIC APU_DECLARE_STATIC WIN32 First try: _DEBUG _USRDLL DLL_EXPORTS LOG4CXX_STATIC APR_DECLARE_STATIC APU_DECLARE_STATIC WIN32 Result: a log4cxx.lib file with 37MB Second try: I delete anything that shows DLL.. :) _DEBUG LOG4CXX_STATIC APR_DECLARE_STATIC APU_DECLARE_STATIC WIN32 Result: a log4cxx.lib file with 37MB It is important to notice that in both cases the library is built by the compiler with no complaints at all... 2) I try to build my applications.. I do use the LOG4CXX_STATIC preprocessor directive and I do include the indicated libs... (advapi32.lib, mswsock.lib, shell32.lib, WS2_32.lib, log4cxx.lib) OBS: I also tried to insert APR_DECLARE_STATIC and APU_DECLARE_STATIC in the directives (I guess it is not necessary at all), but with no change... But no matter what I do, I always get a lot of messages complaining about apr and apr_util, just like these: 1>log4cxx.lib(serversocket.obj) : error LNK2019: unresolved external symbol _apr_p...@20 referenced in function "public: class log4cxx::helpers::ObjectPtrT<class log4cxx::helpers::Socket> __thiscall log4cxx::helpers::ServerSocket::accept(void)" (?acc...@serversocket @help...@log4cxx@@qae?av?$objectp...@vsocket@help...@log4cxx@@@2...@xz) 1>log4cxx.lib(socket.obj) : error LNK2019: unresolved external symbol _apr_socket_conn...@8 referenced in function "public: __thiscall log4cxx::helpers::Socket::Socket(class log4cxx::helpers::ObjectPtrT<class log4cxx::helpers::InetAddress> &,int)" (??0soc...@helpers@log4cxx@@q...@aav ?$objectp...@vinetaddress@help...@log4cxx@@@1...@h@Z) 1>log4cxx.lib(datagramsocket.obj) : error LNK2001: unresolved external symbol _apr_socket_conn...@8 1>log4cxx.lib(socket.obj) : error LNK2019: unresolved external symbol _apr_sockaddr_ip_...@8 referenced in function "public: __thiscall log4cxx::helpers::Socket::Socket(struct apr_socket_t *,struct apr_pool_t *)" (??0soc...@helpers@log4cxx@@q...@pauapr_socket_t@@PAUapr_pool_t@@@Z) 1>log4cxx.lib(inetaddress.obj) : error LNK2001: unresolved external symbol _apr_sockaddr_ip_...@8 Notice that there are LNK2019 and LNK2001 errors. Does anyone have any idea on what am I doing wrong? As I understand those messages the linker is complaining about a function from apr...... but when I do build the lib4cxx static library, I guess those apr and apr_util functions are built in together with lib4cxx... I also tries to simply put the apr and apr_util libs in the lib path, and even include directly on my project.. no success and no change in behavior... I did not buils apr and apr_utils before log4cxx, cause (I guess) it is not necessary.. simply building log4cxx from the VS project does that. Best regards, Ricardo
