JFFS2 kernel support

Hello all

I'm trying to add jffs2 support to a kernel (3c120 dev board) and I'm facing an strange problem.

If I checked in jffs2 support in menuconfig, _after_ compiling the kernel core and

_while compiling_ the apps , the compile process barfs

 || ( touch mtd-utils/.sgbuilt_user && make -C mtd-utils ) || exit $?

The strange thing is that it tries to compile mkfs.jffs2 using my x86 gcc compiler

:confused:

If I try to disable mtd-utils, it doesn't mind; same error while compiling mkfs.jffs2 in mtd-utils which I have previously disabled....

Adding kernel support for MTD and user apps. support for mtd-utils works fine.

No errors. It only happens when adding jffs2 kernel support and while compiling mkfs.jffs2 (mtd-utils enabled or not)

Any hints?

TIA
