Intel compiler icc version 7.1 handles the -MF option inconsistently. Documentation states that it has to be used together with -M or -MM. If used with -MD, for example, it will replace the file ending with .d:
$ icc -M -MF foo.bar conftest.c $ ls conftest.c foo.bar $ rm foo.bar $ icc -MD -MF foo.bar -c conftest.c $ ls conftest.c conftest.o foo.d Subsequently, the depcomp 'icc' mode will not be detected correctly during the ./configure run, since it uses '-MD -MF'. Not too experienced with depcomp and automake, I would guess the ideal solution were to fix this within the compiler, but for current installations the depcomp script might need adjustment. Any suggestions? Which compiler version is the current depcomp supposed to work with? Regards, Ralf
