pppd in eldk

pppd in eldk

[Antonio Di Bacco]

I didn't find the ppp package in denx eldk, I tried to cross compile the 
sources (from sourceforge) but I received some errors (pcap_t undeclared). 
Before I continue I would investigate if someone was already successful with 
ppp on ppc.

Bye,
Antonio.

We compiled pppd v. 2.4.1 with eldk 3.0 on our ppc target with nfs
mount. It was no problem. But compiling this package on our x86 linux
machine (SuSe 9.0)  wasn't a problem either after setting the
environment vars CC, LD, AS to appropriate values (ppc_82xx-...).

Bye

I compiled pppd 2.4.3 slightly modifying the Makefile (attached). Now I want 
to use it to connect two segments of the same LAN. I'm working.

Bye,
Antonio.
