I've been trying to compile "fdutils" but the make command fails with an error message lex: command not found As fas as I can tell, it's occurs at the following lines in the Makefile: lex.%.c: %.lex lex -P$* $< My distribution (SuSE 7.2) does not have a command "lex" that I can find, nor is it part of the fdutils tarball. Can anyone tell me where I find "lex" ?
