Hi,
I am trying to port user-mode-linux(uml) to Sparc64 arch. I am running a
custom built 2.4.18 kernel on debian (sid), Ultra 1 system. I have also
created static links sparc64-linux-ld and sparc64-linux-as. When I build
the uml sources, I am getting the following linker error:
gcc-3.0 -Wall -Wstrict-prototypes -Wno-trigraphs -O2
-fomit-frame-pointer -fno-strict-aliasing -fno-common -U__sparc64__
-Usparc64 -m64 -pipe -mno-fpu -mcpu=ultrasparc -mcmodel=medlow
-ffixed-g4 -fcall-used-g5 -fcall-used-g7 -Wno-sign-compare

I am using gcc-3.0 with binuitls 2.12.90.0.0.1-5. When I tried using gcc
with egcs64, it gave me a bunch of parse errors. Hence, I switched to
gcc-3.0. But now, I have this linker error. Any pointers in this
direction would be appreciated.

gcc-3.0 may not work well. Eitherway, copy the CFLAGS/LDFLAGS from
arch/sparc64/Makefile. For this example above, you are missing -m64 as
an option to make it output 64bit executables.

Oh, my mistake. The CFLAGS are fine, but the LDFLAGS aren't. Looks like
it is missing "-m elf64_sparc".
