[Users] Porting problem on IBM ppc

[Hee Il Kim]

Thanks Erik,

I was trying to get the latest config.guess and config.sub since last night.
So I tried the files from the lastest libtool package. Without the
HOST_MACHINE option, Cactus recognized my system as
powerpc64-unknown-linux-gnu.

...
checking host system type... powerpc64-unknown-linux-gnu
...

But failed to identify f90 compiler

...
Unknown Linux f90 compiler.
Please add appropriate information to
  /home/hmlee/Cactus/lib/make/known-architectures/linux
and send the updated file to CactusMaint
...

So I'm going to make a new known-architecture. But I don't know how to name
the new architecture file, i.e,
~/Cactus/lib/make/know-architectures/???_new_arch_???

It's too tough for me to read out the related Cactus files. Could you tell
me the naming skeme?

Thanks,

Hee Il
