Hi All, I'm having trouble with #includes, seemingly, to find the library functions needed by \pjproject-0.8.0\pjlib\include\pj\ctype.h . The compiler can't find isalnum, isalpha, etc. I'm using Visual Studio 2008 (Windows XP SP2) . My project is in C:\Documents and Settings\User\My Documents\Xxxxxx\XXXX_XXX_XXX\_My_VS2008_projects\PJSIP080612\ . I've put PJSIP in C:\Documents and Settings\User\My Documents\Xxxxxx\XXXX_XXX_XXX\pjproject-0.8.0\ in VS 2008 (VC++ 2008) Project - Properties (Alt+F7) - Configuration Properties - C/C++ - General - "Additional Include Directories" I've added the following: (which made a major improvement in getting as far as I have) C:\Documents and Settings\User\My Documents\Xxxxxx\XXXX_XXX_XXX\pjproject-0.8.0\pjsip\include C:\Documents and Settings\User\My Documents\Xxxxxx\XXXX_XXX_XXX\pjproject-0.8.0\pjsip\lib C:\Documents and Settings\User\My Documents\Xxxxxx\XXXX_XXX_XXX\pjproject-0.8.0\pjmedia\include C:\Documents and Settings\User\My Documents\Xxxxxx\XXXX_XXX_XXX\pjproject-0.8.0\pjmedia\lib C:\Documents and Settings\User\My Documents\Xxxxxx\XXXX_XXX_XXX\pjproject-0.8.0\pjlib-util\include C:\Documents and Settings\User\My Documents\Xxxxxx\XXXX_XXX_XXX\pjproject-0.8.0\pjlib-util\lib C:\Documents and Settings\User\My Documents\Xxxxxx\XXXX_XXX_XXX\pjproject-0.8.0\pjlib\include C:\Documents and Settings\User\My Documents\Xxxxxx\XXXX_XXX_XXX\pjproject-0.8.0\pjlib\lib C:\Documents and Settings\User\My Documents\Xxxxxx\XXXX_XXX_XXX\pjproject-0.8.0\pjlib\include\pj I tried adding the following includes as in the listing that follows: #include <ctype.h> // attempt for isalnum() #include <tchar.h> // attempt for isalnum() #include <locale> // attempt for isalnum() #include <stdlib> , stdlib.h. -but they didn't help clear up any errors, seemingly (maybe some changes further down, but not to the first few compile errors). Please see the program listing and build log output, below. How can I clean up these first few errors? The code is selected from the example in pjproject-0.8.0\pjsip-apps\src\samples\ simpleua.c .
