genext2fs: couldn't allocate a block (no free space)

Hi all,

I had a working mmu linux, but after adding few more modules, the make fails.

What could be the solution ? (my hard disk isn't full :))

Thanks. 

make image.rootfs.all
make: Entering directory `/home/linux_nios/nios2-linux/uClinux-dist/vendors/hvse/nmu400'
/home/linux_nios/nios2-linux/uClinux-dist/user/genext2fs/build-host/genext2fs -m 0 -i 1024 -b 8192  -d /home/linux_nios/nios2-linux/uClinux-dist/romfs -D device_table.txt /home/linux_nios/nios2-linux/uClinux-dist/images/rootfs.ext2
/home/linux_nios/nios2-linux/uClinux-dist/user/genext2fs/build-host/genext2fs: couldn't allocate a block (no free space)
make: ***  Error 1
make: Leaving directory `/home/linux_nios/nios2-linux/uClinux-dist/vendors/hvse/nmu400'

    Try increasing the size of the romfs image (-b 8192 to -b 16384). The message indicates that you've run out of space.

    Thank you Slacker.

    It sounds good to increase the size of this, but I've looked for the definition place of this parameter:

    I found that it is defined in uClinux-dist/user/Kconfig:

    config USER_RAMIMAGE_RAMFS8192

    bool "8192K"

    There is other choices from 64k up to 8192k, but no more !

    So is it really possible to increase that ?

    Anyway I find an alternative solution in removing "cxx c++ test apps" from the build (saves about 1 500k !)
