Hi Craig, After a long time, I have tried to compile the PWLIB - Atlas, Mimas and Pandora - using MSVC6 with latest PSDK - all path settings both in MSVC and System Environment - that makes PSDK paths precede the VC98 paths. I keep getting 3 errors in each compile at:- (2 errors) wspiapi.h(45) :- char (&__wspiapi_countof_helper(__CountofType (&_Array)[_N]))[_N]; (1 error) assert.cxx(163) :- #include <imagehlp.h> This may have something to do with the latest PSDK. The specific errors are:- Performing Custom Build Step on ..\common\getdate.y ../common/getdate.y contains 8 shift/reduce conflicts and 18 reduce/reduce conflicts. Compiling... assert.cxx C:\PROGRAM FILES\MICROSOFT PLATFORM SDK\INCLUDE\wspiapi.h(45) : error C2265: '<Unknown>' : reference to a zero-sized array is illegal C:\PROGRAM FILES\MICROSOFT PLATFORM SDK\INCLUDE\wspiapi.h(45) : error C2265: '<Unknown>' : reference to a zero-sized array is illegal C:\HOME\pwlib\src\ptlib\msos\assert.cxx(163) : error C2856: #pragma hdrstop cannot be inside an #if block Error executing cl.exe. ptlibs.lib - 3 error(s), 0 warning(s) Kindly advise how to solve the above proble,.
