Hi,
I am currently trying to crosscompile pppd with the ELDK 2.0 toolchain.
To build in a native Intel RedHat 7.2 environment was no problem.
However, when trying to crosscompile it seems that there are more things than CC and the PATH to be altered. By changing the include file search path, I was able to build chat, but pppd seems to be a little harder. Is there anyone out there that might have some clues?
Kind regards,
Tord

Your output tells me the include paths in your eldk may be broken ( or
something went wrong during eldk install ).
If eldk path is '/opt/eldk', what do you have for the following:
/opt/eldk/ppc_8xx/usr/include/linux
/opt/eldk/ppc_8xx/usr/include/asm
They should be links like so:
/opt/eldk/ppc_8xx/usr/include/linux --> ../src/linux/include/linux/
/opt/eldk/ppc_8xx/usr/include/asm --> ../src/linux/include/asm/
Do the directories the links point to exist?
---
Optionally, and I've seen some say this shouldn't be done, I point those two
links to my target's kernel include paths.
/opt/eldk/ppc_8xx/usr/include/linux -->
/home/me/project/src/linux/include/linux/
/opt/eldk/ppc_8xx/usr/include/asm -->
/home/me/project/src/linux/include/asm/
I've never had a problem with this and its done like that on my host system as
well ( '/usr/include/linux' --> '/usr/src/linux/include/linux', etc ).
