Hi Vin,

If you look in dist/lfs-5.1/gcc there are some gcc spec files.  These
are rpm spec files which ltib uses to build gcc.  The best way for you
to get a working gcc-4.1.1 for arm eABI targets is to make a copy of
gcc.spec in this directory and call it gcc-4.1.1.spec  Then you need to
modify this file accordingly so that it builds an arm eabi target.

Once you have done this you need to edit
config/platform/imx31ads/pkg_map and add the following line:

PKG_GCC =  gcc-4.1.1

That should get ltib to build gcc-4.1.1 for the imx31ads BSP,

Best regards,

Steve
