Subject: [ptxdist] kernel config question
Date: Thu, 15 May 2014 14:07:51 +0200 [thread overview]
Message-ID: <5374AE17.6070101@railtec-systems.ch> (raw)
Hello,
I want to configure the kernel after it was unfolded and patched within
the platform/build-target/linux-3.0.31
directory, so I did change to this dir and copied the kernelconfig from
the configs-direcory of ptxdist as .config:
~/svn/ptxdist/ptxdist_CPU/platform/build-target/linux-3.0.31>cp
../../../configs/kernelconfig ./.config
then I did a "make menuconfig", did *NOT* change anything but only saved
the config before exiting
upon getting the question if I want to save the config.
=>as a result there is a completely different .config file. (For not
bothering you with details, here is
just the linecount of the different lines in .config and the .config before:
diff .config ../../../configs/kernelconfig|wc -l
267
)
When I try to build the kernel with
"make -j2 HOSTCC=gcc ARCH=i386 CROSS_COMPILE=i686-unknown-linux-gnu-
clean bzImage"
now there is a whole bunch of questions regarding some specific
configurationissues, starting with
"
make -j2 HOSTCC=gcc ARCH=i386 CROSS_COMPILE=i686-unknown-linux-gnu-
clean bzImage
HOSTCC scripts/kconfig/conf.o
HOSTCC scripts/kconfig/zconf.tab.o
HOSTLD scripts/kconfig/conf
scripts/kconfig/conf --silentoldconfig Kconfig
*
* Restart config...
*
*
* Enable the block layer
*
Enable the block layer (BLOCK) [Y/?] y
Support for large (2TB+) block devices and files (LBDAF) [Y/n/?] (NEW)
"
So as I found out the first modification above COULD be explained that
the kernelconfig and the actual
kernelversion might differ (but I did not check whether this is the case).
But I do absolutely not understand that I still got those questions when
trying to crosscompile.
BTW fyi: if I do a native compile "make bzImage", there are no questions.
Would be nice to understand this behavior, maybe somebody does and can
explain to me.
Thanks an advance for any help or hint,
Marc
