Hi Claudia,
The m532xevb is an MMUless platform and does not have a fully supported
package set in LTIB. In many ways your best bet is to use uClinux-dist
(http://www.uclinux.org/pub/uClinux/dist/) for MMUless platforms.
However I just took a quick look and I don't think that has support for
libpng either.
You could try enabling "zlib" in the package configuration (./ltib
--configure) and see if that helps.
I suspect you got the BSP from a Freescale ISO image, in which case you
should try send your support queries to Freescale. To do this:
* go to http://www.freescale.com
* click on "Support / Technical support"
* click on "Submit a Service Request"
* register to get a user name and password.
* login in with your user name and password
* on the "New Service Request" page:
* category = Technical Request
* topic = Linux BSP
* Click on "Continue"
* fill out the information for the service request
* click on the "Submit" button at the bottom of the page.
Regards, Stuart

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
