I have reason to believe that the make program supplied with the June build of RedHat IA64 is unable to handle targets with names like 'subdir/outfile'. The usual behavior is to create 'subdir' if it does not exist and output to 'outfile'. This version of make couldn't handle it and exits with an error. It can create the directory but it will exit with errors. Running make with debug on shows it lost the child process. A temporary workaround in the make files is to create the directory first before outputting to the file.
My experience (and a search of make.info for subdir) indicate no behavior of make that automagically creates a subdir that is prefixed in a target. Can you send a short example Makefile that illustrates what you expect make to do on ia64? BTW, you might look for make-3.79.1 as that is the latest version we are building on ia64.
closed, lack of input.
