Hi Hesham, I was too brief describing the last step. You must make getopt.h and getopt.c look like other PJLIB headers, sources. I.e. begin getopt.h with PJ_BEGIN_DECL (I think you have to #include <pj/config.h>, if it is not) and end with PJ_END_DECL. All public declarations must be made using PJ_DECL or PJ_DECL_DATA macros. Symbols declared in such way must be defined using PJ_DEF or PJ_DEF_DATA respectively in getopt.c. I do not know why, but I experienced this was not enough. Adding _pj_getopt_long to Force reference symbols linker option at PJSUA_LIB project does the job. I would like to suggest this patch to be merged with the trunk source code. Maybe it is just a problem of Visual Studio but the proposed changes are harmless on other platforms.
