 In general, we don't provide DLL projects for Windows, but please see [http://www.pjsip.org/pjlib/docs/html/group__pj__dll__target.htm Building Dynamic Link Libraries] page in PJLIB documentation on how to build these DLL yourself.

+=== Configuration macros are not set properly by configure script === #crlf
+
+Q: After running {{{./configure}}} script successfully, {{{make}}} returns this error:
+ {{{
+ ..
+ ../../pjlib/include/pj/config.h:1006:4: error: #error 
+ "PJ_HAS_HIGH_RES_TIMER is not defined!"
+ ../../pjlib/include/pj/config.h:1022:4: error: #error 
+ "PJ_EMULATE_RWMUTEX should be defined in compat/os_xx.h"
+ ..
+ }}}
+ 
+ And upon inspecting {{{pjlib/include/pj/compat/os_auto.h}}}, all macros are undefined:
+ {{{
+ ...
+ /* Canonical OS name */
+ /* #undef PJ_OS_NAME */
+ 
+ /* Legacy macros */
+ /* #undef PJ_WIN32 */
+ /* #undef PJ_WIN32_WINNT */
+ ...
+ }}}
+
+ However {{{config.log}}} shows that these macros have been resolved properly:
+ {{{
+ ..
+ ## ----------- ##
+ ## confdefs.h. ##
+ ## ----------- ##
+
+ #define HAVE_INTTYPES_H 1
+ #define HAVE_LIBM 1
+ #define HAVE_LIBNSL 1
+ #define HAVE_LIBPTHREAD 1
+ }}}
+
+A: According to this discussion entitled [http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2008-May/002915.html Error in configuring SVN version, on Linux, i686] on pjsip mailing list, this was caused by incorrect CRLF line endings in the {{{pjlib/include/pj/compat/os_auto.h.in}}} file, causing {{{sed}}} to fail. If you're working on Linux, make sure that you use the {{{.tar.gz}}} tarball rather than the {{{.zip}}} file since both have different CRLF formatting, and be careful when transferring/editing source files between your Linux and a Windows machine.
