Hi Andi, I recall I have a mail from you about this. Last time I looked I could not figure out what was wrong, but let me try again. Could you send me the output of "make V=1" for an otherwise clean compile. Sam ^ permalink raw reply [flat|nested] 11+ messages in thread

When doing a "make" inside an already compiled kernel source there
shouldn't be anything rebuilt. I've identified three places where this
isn't the case in recent 2.6 kernels:
1. ikconfig
CC kernel/configs.o
even when the .config wasn't changed
2. pnmtologo
The following happens again once, but not when doing a third "make":
./scripts/pnmtologo -t mono -n logo_linux_mono -o drivers/video/logo/logo_linux_mono.c drivers/video/logo/logo_linux_mono.pbm
CC drivers/video/logo/logo_linux_mono.o

./scripts/pnmtologo -t clut224 -n logo_linux_clut224 -o drivers/video/logo/logo_linux_clut224.c drivers/video/logo/logo_linux_clut224.ppm

Compile.h contains date when kernel was compiled, and gets updated each time there is new .o files.

Only lightly tested here. Tested it a bit more, it was not good. Corrected patch follows. I had to spell out the dependencies, otherwise make saw them as implicit targets, and deleted the .c files afterwards. Btw the patch contains some general clean-up as well, unrelated to the 'spurious recompile' issue.
