Hello, I have just tried to build webkit on my windows machine (svn revision 14621). I think everything is set up properly. I get the following logs : - - - - - Building under x: drive 6 archives were successfully processed. Synching \S60\LayoutTests with \epoc32\winscw\c\LayoutTests 0 LayoutTests files updated 0 LayoutTests files removed WARNING: Cannot determine the version of the RVCT Compiler. In file included from .\BLD.INF:1: S60Internals\S60.hrh:1: ..\..\epoc32\include\variant\Symbian_OS_v9.1.hrh: No suc h file or directory BLDMAKE ERROR: ERROR: cpp.exe returned non-zero exit status (8448) cpp.EXE -undef -nostdinc -+ -I ..\epoc32\include -I . -I .\ -I ".\S60I nternals" -include S60Internals\S60.hrh ".\BLD.INF" - - - - - The file Symbian_OS_v9.1.hrh is required, but does not seem to be part of the S60 SDK fo symbian OS, for C++; third edition. I have noticed that "..\..\epoc32\include\" is there, but does not contain any variant directory. Any ideas ? Thanks Ronan
