Hi, no depencies set --- it is obvious. To the second problem: Yes, this is the only error and I found out what it is caused by, perhaps. Function pj_throw_exception_() is declared in the header as: PJ_DECL_NO_RETURN(void) pj_throw_exception_(pj_exception_id_t id) PJ_ATTR_NORETURN; and in the source it is defined as: PJ_DEF(void) pj_throw_exception_(int exception_id) So the error is that PJ_DECL_NO_RETURN does not declare a function with dllexport, but PJ_DEF does. Pjsua-lib library compiled as DLL works fine with empty PJ_EXPORT_DEF_SPECIFIER so for my purposes I commented out the line in cc_msvc.h. But if someone wants to call pj_throw_exception_() from the host application, it must be declared dllexport as well. Declaring function with dllexport in forward declaration (header) is enough. Doing so in definition is needless then.

I never tried to build the libraries as DLL myself, so any feedbacks on this will be good. > First problem: > In the solution there are no depencies on other projects so the projects > won't be built and linked.

As a static library, pjsua-lib does not need to have dependencies to other libs, hence the dependencies were not set. > Second problem: > See following compiler error: > > c:\pjproject-0.8.0\pjlib\src\pj\except.c(41) : error C2375: > 'pj_throw_exception_' : redefinition; different linkage > c:\pjproject-0.8.0\pjlib\include\pj\except.h(302) : see declaration of > 'pj_throw_exception_' Was this the only error that you get?

So does the DLL work? Do you see symbols exported from the DLL? I kinda expect that this wouldn't work, as you just disabled the syntax to export the symbols. But I could be wrong! -benny > Have a nice day. > Vali _______________________________________________ Visit our blog: http://blog.pjsip.org pjsip mailing list pjsip at lists.pjsip.org http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org
