[HELP] ARM Cross Compilation Toolchain

[E3V3A]

Ok, so the "good" news is that I installed xubuntu and ran the same stuff using the VDLinx tools chain. I get the same errors!!
Why is this good? Because it means that my cygwin + CodeSourcery tool chain is working, but we're missing something to make it compile my modules...

These are the errors:

Code: Select all

I tried "make all" using VDLtoolchain, and copied Module.symver to ..../mods/. That resolved the "WARNING" message...

here one exercise for free, normally i'll take 1300? + vat per head for it. feel free to wikifi it.

(now kernel sources are in: ~/SELP/VDLinux_2.6.35.11/linux-2.6.35.11)

extract toolchain:

Code: Select all

tar xvzf VDLinux-ARMv7-4.4-202-toolchain-v2r2-20110630.tgz

!!!!!!!!!!!!! big problem is that my partition not support symlinks !!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!! expect troubles on kernel compile !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

make life easier with some enviroment variables:

Code: Select all

export PATH=$PATH:~/SELP/VDLinux-ARMv7-4.4-202-toolchain-v2r2-20110630/bin
export ARCH=arm
export CROSS_COMPILE=arm-v7a8v2r2-linux-gnueabi-

let see if we have all host tools what we need for kernel compile:

Code: Select all

cd ~/SELP/VDLinux_2.6.35.11/linux-2.6.35.11
cp arch/arm/configs/Echo.P_defconfig_release .config
make menuconfig

you should see funny linux configuration menu, btw. just exit from it (don't save or mess around here...)

now we try to compile one module:

Code: Select all

make SUBDIRS=fs/rfs modules

oha, error ->

SpoilerShow

make: arm-v7a8v2r2-linux-gnueabi-gcc: Kommando nicht gefunden

1. maybe due missing symlinks?
check it:

Code: Select all

not so funny, it has version in name and it's not executable, lol never use FAT32 for such things...

so we move to NTFS partition on c: drive:

Code: Select all

cd ~
mv SELP /cygdrive/c/

and fix PATH enviroment variable:

Code: Select all

export PATH=$PATH:/cygdrive/c/SELP/VDLinux-ARMv7-4.4-202-toolchain-v2r2-20110630/bin

and go to new directory:

Code: Select all

cd /cygdrive/c/SELP

we make a cleanup there and extract packages again, maybe we can save troubles with symlinks easy.:

Code: Select all

rm -rf VDLinux_2.6.35.11 VDLinux-ARMv7-4.4-202-toolchain-v2r2-20110630 

and you can remember what we did before? than again (you can use cursor up button to get prev. commands...):

Code: Select all

tar xvzf VDLinux-ARMv7-4.4-202-toolchain-v2r2-20110630.tgz

we check for symlinks and executable flag:

cp arch/arm/configs/Echo.P_defconfig_release .config

extract it:

tar xvjf arm-linux-toolchain-cygwin-2010q1.tar.bz2

remove samsung toolchain -> it's unusable for cygwin:

Code: Select all

rm -rf VDLinux-ARMv7-4.4-202-toolchain-v2r2-*

let fix us enviroment variables for the new toolchain (you can also use Ctr-r and start to type export CR, see the magic):

Code: Select all

export CROSS_COMPILE=arm-linux-
export PATH=$PATH:${PWD}/arm-linux/bin

(oha, we use here other variable PWD. nice, isn't it?)

little enviroment check:

Code: Select all

which ${CROSS_COMPILE}gcc

SpoilerShow

/cygdrive/c/SELP/arm-linux/bin/arm-linux-gcc

we start check again to compile a kernel module, but keep in mind we use a different cross-toolchain!!!

Code: Select all

cd VDLinux_2.6.35.11/linux-2.6.35.11

make SUBDIRS=fs/rfs modules

SpoilerShow

make: arm-v7a8v2r2-linux-gnueabi-gcc: Kommando nicht gefunden

so seems samsung had it hardcoded, but the kernel buildsystem is more powerfull..

Code: Select all

grep arm-v7a8v2r2-linux-gnueabi * .*

SpoilerShow

.config:CONFIG_CROSS_COMPILE="arm-v7a8v2r2-linux-gnueabi-"

aha, it's set in .config, we can change it with "make menuconfig", but let us try the force of kernel-buildsystem:

Code: Select all

make CONFIG_CROSS_COMPILE=${CROSS_COMPILE} SUBDIRS=fs/rfs modules

uh, some errors:

SpoilerShow

arm-linux-ld: failed to merge target specific data of file fs/rfs/base/ess_bitmap.o
arm-linux-ld: fs/rfs/rfs_glue.o: Unknown mandatory EABI object attribute 44

we need a toolchain what better match the samsung's version (more exactly the binutils)
before we search the web like stupid we build our own version.
samsung use binutils 2.19, on toolchain from sourceforge we have 2.20.
hm, we build the latest one (just for fun):

Code: Select all

cd -
wget http://ftp.gnu.org/gnu/binutils/binutils-2.23.tar.gz
tar xvzf binutils-2.23.tar.gz
mkdir BUILD_binutils
cd BUILD_binutils

make

install it, save install-logfile if you like to inspect it later:

Code: Select all

make install > my.log 2>&1

check the version of ld command:

Code: Select all

arm-linux-ld -v

SpoilerShow

GNU ld (GNU Binutils) 2.23

so we start again with virgin samsung kernel-sources:

Code: Select all

cd ..
rm -rf VDLinux_2.6.35.11
tar xvzf VDLinux_2.6.35.11.tgz
cd VDLinux_2.6.35.11/linux-2.6.35.11
cp arch/arm/configs/Echo.P_defconfig_release .config

time to change the mental level
if someone (in this case samsung) shipps precompiled object files with the kernel sources, it has to be suffixed as _shipped.
now we fix this (at least for rfs):

Code: Select all

for obj in $(find fs/rfs/ -name "*.o" | grep -v -E "(.mod.|built-in)") ; do mv -vf $obj ${obj}_shipped ; done

instead of make menuconfig we use magic command. kernel need some little helpers...:

Code: Select all

make CONFIG_CROSS_COMPILE=${CROSS_COMPILE} prepare scripts

and try to compile rfs module (again...):

Code: Select all

make CONFIG_CROSS_COMPILE=${CROSS_COMPILE} M=fs/rfs modules

, erros again:

end of lesson, no need to mess around in kernel sources and kill kernels build-system or change anything in kernels Makefile

[E3V3A]

The make error 127 means that the file cannot not be found. But the file IS in where it should be, which make me believe that the error is in the shell interpretation of the Makefile...

The Error:

Code: Select all

...
/bin/sh: scripts/mod/modpost: No such file or directory

/cygdrive/d/zarm/vdl_kernel/linux/linux-2.6.35.11/Makefile:1354: recipe for target `modules' failed

(What does modpost do?)

with more debug on:

/bin/sh: scripts/mod/modpost: No such file or directory
...

I think this originates from here (in the Makefile):

Code: Select all

...
PHONY += modules
modules: $(vmlinux-dirs) $(if $(KBUILD_BUILTIN),vmlinux) modules.builtin
	$(Q)$(AWK) '!x[$$0]++' $(vmlinux-dirs:%=$(objtree)/%/modules.order) > $(objtree)/modules.order
	@$(kecho) '  Building modules, stage 2.';
	$(Q)$(MAKE) -f $(srctree)/scripts/Makefile.modpost
	$(Q)$(MAKE) -f $(srctree)/scripts/Makefile.fwinst obj=firmware __fw_modbuild

modules.builtin: $(vmlinux-dirs:%=%/modules.builtin)
	$(Q)$(AWK) '!x[$$0]++' $^ > $(objtree)/modules.builtin

%/modules.builtin: include/config/auto.conf
	$(Q)$(MAKE) $(modbuiltin)=$*
...

I don't understand what this does, but I guess the first thing to go tilt, when using incompatible (or outdated) shell commands, are stuff related to AWK and the output of certain variables, such as "!x[$$0]++"...

Perhaps if someone could send me a working Makefile for different MST (ARM) firmware of the same or similar Kernel version??

But you get with this method gnu eabi binaries and not eabi5!

Which method do you refer to? My method or yours?
I don't know what difference it would make. I think my way yields EABI 4 by default, but that it can be set in assembler somehow.
And in addition I'm not sure it makes a difference unless you intend to run in thumb-mode... But I don't know.

Second I still have some troubles ... I get:

Which method do you refer to? My method or yours?

with the gcc from sourceforge

I don't know what difference it would make. I think my way yields EABI 4 by default, but that it can be set in assembler somehow.
And in addition I'm not sure it makes a difference unless you intend to run in thumb-mode... But I don't know.

not really tested but i'm sure denny had some troubles as he tried to load eabi5 binaries on system with glibc eabi4 or vice versa....

Second I still have some troubles ... I get:

PS. If your compilation setup is working, please open a new shell window and post the output of the following commands:

1. "set"
2. "export"
3. "shopt"

I think perhaps there's something funny going on in my BASHOPTS and/or SHELLOPTS variables...
