Hi Meino, |
| 43 |
|
| 44 |
Unfortunately GNU Make changed the rules on Makefiles (or decided to |
| 45 |
enforce a rule that wasn't previously enforced, I don't know which) and |
| 46 |
the kernel Makefiles were caught out by it. |
| 47 |
|
| 48 |
The later kernels have the changes made that are necessary but if you're |
| 49 |
building an older kernel with a newer make then you'll run into this |
| 50 |
problem. |
| 51 |
|
| 52 |
You can look at newer kernel source to find the changes necessary. |
| 53 |
|
| 54 |
In the case above, the imlicit rule is the %config target and the normal |
| 55 |
rule is the config target. |
| 56 |
|
| 57 |
You can just separate those into two separate rules with the same |
| 58 |
recipes. |
| 59 |
|
| 60 |
For example: |
| 61 |
config: scripts_basic outputmakefile FORCE |
| 62 |
$(Q)mkdir -p include/linux |
| 63 |
$(Q)$(MAKE) $(build)=scripts/kconfig $@ |
| 64 |
$(Q)$(MAKE) -C $(srctree) KBUILD_SRC= .kernelrelease |
| 65 |
|
| 66 |
%config: scripts_basic outputmakefile FORCE |
| 67 |
$(Q)mkdir -p include/linux |
| 68 |
$(Q)$(MAKE) $(build)=scripts/kconfig $@ |
| 69 |
$(Q)$(MAKE) -C $(srctree) KBUILD_SRC= .kernelrelease |
| 70 |
|

Regards, |
