[Buildroot] Build error

[Buildroot] Build error

[Shashi Ranjan]

This Error comes if you try to call a function which is lecated at far address from the calling point.
Define that function in the same file to get away with this problem...

Any one knows better solution for this?

[Buildroot] Build error

[Will Wagner]

Hi all

I am trying to build for an arm target. I have successfully built an 
image with just the basic packages selected by default. However I then 
add in the qtopia4 package and nothing else and get this error when 
trying to link the kernel:

Can someone explain what the errors mean? It appears to be an error when 
linking the kernel but how can adding a package cause this?

Any help is much appreciated.

Will.

Hi Will,

try to compile kernel/buildroot with make V=1
and compare compiler options passed to kernel in both cases - with and without qtopia

Ivan

[Buildroot] Build error

[Will Wagner]

Thanks for the hint.

I have compiled both with and without qtopia4 and got the verbose log. I 
can not see any difference on what is on the command line between the 
two versions.

Output is now:

   set -e; if [ ! -r .version ]; then rm -f .version; echo 1 >.version; 
else mv .version .old_version; expr 0$(cat .old_version) + 1 >.version;

It seems to be failing when building init, is that right? What files are 
taken from the staging dir for this step? Presumably the qtopia4 build 
process must be overwriting one of these? I assume this is the case as 
if I now deselect qtopia4 package the build still fails in the same way.

Anyone able to give me any help on what is mean to be happening here 
would be great.

Thanks

Will.

Will,

I can suggest as workaround to set BR2_KERNEL_none=y
and build kernel outside a buildroot tree and see if it working this way.

[Buildroot] Build error

[Will Wagner]

Ivan,

Thanks for your help. Think I have worked out the problem. Appeared to 
have too large a rootfs so that the initramfs being built was very 
large. Have worked round it for now by reducing the size of the rootfs 
(qtopia4 was copying some unneeded files).

Any idea what the size limit is for a rootfs used with initramfs?

Thanks,

Will.

Hi Will,

I have not used initramfs, usually qtopia and other large stuff (X.org / GTK ) is run
from jffs2 filesystem on flash, e.g rootfs is not in RAM but in flash.

Have you tried to adjust these kernel settings:
CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_RAM_COUNT=1
CONFIG_BLK_DEV_RAM_SIZE=14000
CONFIG_BLK_DEV_RAM_BLOCKSIZE=1024

?

Regards,
Ivan
