Hallo, This is the second mail on the same subject. Eason: the first mail contained non plain text. Now, I have copied the same information by hand: In all my source files the # include statement produces the same error (with different names): /ONTW/C/GEN/SRC_F/DB.C (or other names) : FATAL ERROR: DB.IMP: FILE NOT FOUND As far as I know, I have not changed anything in - the include statements - in the UNIX scripts - the CPATH variable\ I have two questions: - Can the compiler publish the search paths, being used. and how? - Any suggestions (short question - long answer?) With kind regards, Bob Gardenier
