Subject: 2.6: spurious recompiles
Date: Sat, 6 Sep 2003 22:14:18 +0200	[thread overview]
Message-ID: <20030906201417.GI14436@fs.tum.de> (raw)

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 vga16 -n logo_linux_vga16 -o drivers/video/logo/logo_linux_vga16.c drivers/video/logo/logo_linux_vga16.ppm
  CC      drivers/video/logo/logo_linux_vga16.o
  ./scripts/pnmtologo -t clut224 -n logo_linux_clut224 -o drivers/video/logo/logo_linux_clut224.c drivers/video/logo/logo_linux_clut224.ppm
  CC      drivers/video/logo/logo_linux_clut224.o
  LD      drivers/video/logo/built-in.o
  LD      drivers/video/built-in.o

  drivers/scsi/aic7xxx/aic79xx_reg.h \
                      -p drivers/scsi/aic7xxx/aic79xx_reg_print.c -i

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
