Re: [gentoo-embedded] uClibc and PHP

I got php-cgi running using this patch:

I don't know if this works as a patch as I have just edited the files by hand.
I found it at the uclibc mailing-lists:
http://www.uclibc.org/lists/uclibc/2004-December/010664.html
Which gave me a working php-cgi-4.4.0 on a uclibc-mips. I haven't submitted this to bugs.gentoo.org because I have tweaked alot more by hand and I wasn't sure this was the only patch needed.
This patch solved my __dn_skipname problems but I alsa disabled some more xml-stuff for all the localisation stuff unsupported by uclibc.

I've been trying to compile PHP on the uclibc profile for the last 
couple of days. I am now stuck with an error on __dn_skipname as 
seen below.

I've seen some references to this after googling for a while, some 
of it being quite old. So it's not a new issue. But I haven't 
really found a cure. Hope someone has been there already.

Thanks
Philippe
