BusyBox: Error during make

Question

I try to install BusyBox 1.20.2 on a embedded system with PowerPc. At first I want to try it with the default config. So this are the commands

make defconfig
make

And this is the result:

ma-bash-3.2# make
  CC      miscutils/ubi_tools.o
miscutils/ubi_tools.c: In function 'ubi_tools_main':
miscutils/ubi_tools.c:137: error: 'UBI_DEV_NUM_AUTO' undeclared (first use in this function)
miscutils/ubi_tools.c:137: error: (Each undeclared identifier is reported only once
miscutils/ubi_tools.c:137: error: for each function it appears in.)
miscutils/ubi_tools.c:157: error: storage size of 'req' isn't known
miscutils/ubi_tools.c:165: error: 'UBI_IOCATT' undeclared (first use in this function)
miscutils/ubi_tools.c:157: warning: unused variable 'req'
miscutils/ubi_tools.c:171: error: 'UBI_IOCDET' undeclared (first use in this function)
make[1]: *** [miscutils/ubi_tools.o] Error 1
make: *** [miscutils] Error 2

How is it possible to solve that Error?

Can I disable this ubi_tool ? What effects will that have and how to do that?

Answer 1

Remove these lines in .config:

CONFIG_UBIATTACH=y
CONFIG_UBIDETACH=y
CONFIG_UBIMKVOL=y
CONFIG_UBIRMVOL=y
CONFIG_UBIRSVOL=y
CONFIG_UBIUPDATEVOL=y

you won't have support for ubifs.
