A comparison between the gkauth.cxx files from v2.07CVS and v2.2betaCVS shows that the following files are not included in the latter:- #include <ptlib.h> #include <h225.h> although the following extra file is included in the latter:- #include "RasPDU.h" I put in only the following include into the v2.2betaCVS:- #include <ptlib.h> I now find the elimination of the said error:- gkauth.cxx C:\openh323\openh323gk\gkauth.cxx(566) : error C2039: 'VerifyToken' : is not a member of 'H235AuthSimpleMD5' ..\include\h235auth.h(238) : see declaration of 'H235AuthSimpleMD5' Maybe someone may be able to see if the other files are needed to be included or any other suitable fix is needed. It appears that the define OPENH323_NEWVERSION is set properly under this condition. Regards, Ap.Muthu ------------------------------------------------------- This SF.
