There is no hard coding of directory names, ppc64 vs powerpc64 ?

The exports options for your /usr/netboot/powerpc64 are similar to mine?

/export/netboot/ppc64 -alldirs  192.168.225.60

Added.

Well, I had my problems building world on both powerpc and powerpc64.

On powerpc I failed with some stuff in gdb, bfd_elf64_powerpc_vec
unreferenced...

Helped myself with make -i since I do not need gdb now.

Then in powerpc64 I see the following:

cc -O2 -pipe  -std=gnu99 -fstack-protector -Wsystem-headers -Werror
-Wall -Wno-format-y2k -W -Wno-unused-parameter -Wstrict-prototypes
-Wmissing-prototypes -Wpointer-arith -Wreturn-type -Wcast-qual
-Wwrite-strings -Wswitch -Wshadow -Wcast-align -Wunused-parameter
-Wchar-subscripts -Winline -Wnested-externs -Wredundant-decls
-Wold-style-definition -Wno-pointer-sign  -o uathload uathload.o ar5523.o
ar5523.o: file not recognized: File truncated

I work around with make -i. The dangerous thing, I do not see if there
are further errors...

I rebuild and retest.

Thx,
Andreas
