My Build system

I am running a VM-ware player image with Gentoo Linux placed on a USB hostpowered disc. This does not give highest possible performance, but it allows for a lot of mobility and portability. Peripherals like a (micro)SD-card reader adapter for USB works fine, but the built-in one in my laptop is not available within the VM-ware player.

On my Gentoo linux I set-up the build environment according to the instructions for the overo build system.

The reason for choosing the open-embedded as for Overo is that the Verdex buildsystem has not been updated for approx. a year now and I wanted the latest recipes to get e.g. Open JDK.

Building an Rootfs image and a kernel

First I checked out a copy of (instructions) the Verdex build system. So the home directory now has:

~/gumstix/gusmtix-oe/
~/overo-oe/

Then, I copied the Verdex image recipes to the user.collection.

mkdir -p ~/overo-oe/user.collection/images/
cp ~/gumstix/gumstix-oe/com.gumstix.collection/packages/images/* ~/overo-oe/user.collection/images/

Once copied, I ran:

bitbake gumstix-basic-image

Resulting in a failure and Bitbake reporting that nothing provides some package and exited without building anything. I then copied the recipes for those packages and ran bitbake again. At the end I had copied:

task-base-gumstix
motd
uisp
version
www-content


Gumstix-kernel and sumversion.c

The Gumstix-kernel recipe fails with the error message

warning: unused variable 'filelist'

The problem can be solved by adding '#include <limits.h>' after strings.h in scripts/mod/sumversion.c fixes the issue. The file is found at: ~/overo-oe/tmp/work/gumstix-verdex-angstrom-linux-gnueabi/gumstix-kernel-2.6.21-r0/linux-2.6.21/scripts/mod/sumversion.c

Problems with No GNU_HASH fount in elf

Baking the gumstix-basic-image the process stopped with the I2C package and the log information boiled down to the error message: No GNU_HASH fount in elf for the i2c.

ERROR: QA Issue: No GNU_HASH in the elf binary: '/home/<user>/overo-oe/tmp/work/armv5te-angstrom-linux-gnueabi/i2c-1.0-r2/install/i2c/usr/bin/i2c'

Asking for hints in the gumstix.users mailing list helped alot. Thanks Koen and Philip (archive here) and I could find the problem in the i2c.bb file: The task do_compile ignored the LDFLAGS set by the oe/autoconf tools.

do_compile () {
       ${CC} -o i2c *.c
}

Adding ${LDFLAGS} to the line for compiling solved this problem:

do_compile () {
       ${CC} -o i2c *.c ${LDFLAGS}
}

Then the same problem emerged in the pxaregs recipes and the same solution applied. This resulted in a completed bake.

undefined reference to `__aeabi_uldivmod' in utsname_sysctl.c

In Omap kernel the problem has been solved. Copy the patch from

 # cd ~/overo-oe/org.openembedded.dev/recipes/linux/linux-omap1-2.6.24-omap1 
 # cp timespec_add_ns_avoid_udivdi3.patch ../gumstix-kernel-2.6.21/

In the gumstix-kernel_2.6.21.bb add to the list of files in SRC_URI the following line:

      file://timespec_add_ns_avoid_udivdi3.patch;patch=1 \
