Hello, I am building S60 source tree. I am getting following errors. The trace is rather lengthy. In the beginning there is -- make -s -r -f "\EPOC32\BUILD\S60\MEMMAN\WINSCW\MEMMAN.WINSCW" CLEANUDEB make[1]: \EPOC32\BUILD\S60\MEMMAN\WINSCW\MEMMAN.WINSCW: No such file or directory make[1]: *** No rule to make target `\EPOC32\BUILD\S60\MEMMAN\WINSCW\MEMMAN.WINSCW'.
