Hi, So I've finally succeded in building some libs I need for Windows CE, using STLPort. One of those libs is thread. It builds fine, but when I try to use it from a simple sample I get some link errors (see below). What I wonder is if threads is even possible to use under WinCE? Looking at the code, theres only a folder for pthreads and one for win32, but inside the win32 files there's some UNDER_CE switches. Anyone had success using it under wince? The link errors I get is: Error 1 error LNK2019: unresolved external symbol tss_cleanup_implemented referenced in function "void __cdecl boost::`anonymous namespace'::create_current_thread_tls_key(void)" (?create_current_thread_tls_key@?A0x78389a16@boost@@YAXXZ) libboost_thread-vc80-mt-sgdp-1_40.lib Error 2 error LNK2019: unresolved external symbol gmtime referenced in function "public: static struct tm * __cdecl boost::date_time::c_time::gmtime(unsigned long const *,struct tm *)" (?gmtime@c_time@date_time@boost@@SAPAUtm@@PBKPAU4@@Z) libboost_thread-vc80-mt-sgdp-1_40.lib Thanks!
