Hi,
my name is Claudia De Bartolomeis and
I'm trying to compile libpng in the BSP m532xevb, based on kernel
uClinux 2.6.17.7-uc1 by Freescale, using Ltib.

but it doesn't work.
It seems due to undefined references to zlib functions.

Thanks much for any help with this.
Best Regards
Claudia De Bartolomeis
