I'm interested in trying out the Linux kernel's SunOS and/or Solaris Binary
Emulation but I can't find any documentation that is either recent or complete.
I have scads of Ultra60s lying around, so I loaded up Debian 4.0 on it. I
choose Debian over Ubuntu in this case because Ubuntu doesn't seem to support
SPARCs as desktops, only servers. I want to evaluate how this compares to our
Solaris 8 desktops at some point.
manhack:/usr/gnemul/solaris/bin# cat /proc/cpuinfo

fpu : UltraSparc II integrated FPU

It's a pretty basic load. While not too familiar with Debian in general,
during the install, I select the Default/Basic load + Desktop component, that
is to say not a DNS or mail server or anything else fancy. 817 packages
installed.
manhack:/usr/gnemul/solaris/bin# /bin/uname -a
Linux manhack 2.6.18-5-sparc64-smp #1 SMP Wed Oct 3 04:16:38 UTC 2007 sparc64
GNU/Linux
I've copied some libraries and very basic binaries from a Solaris 8 system,
which is also a U60, to /usr/gnemul/solaris/{original path} and loaded the
solaris.ko kernel module.
manhack:~# lsmod|grep solaris
solaris 57880 0
manhack:~# modinfo solaris
filename:
/lib/modules/2.6.18-5-sparc64-smp/kernel/arch/sparc64/solaris/solaris.ko

Now what?
Any attempt to run a Solaris binary results in the following:
manhack:/usr/gnemul/solaris/bin# file ./uname
./uname: ELF 32-bit MSB executable, SPARC, version 1 (SYSV), dynamically
linked (uses shared libs), stripped
manhack:/usr/gnemul/solaris/bin# ./uname
-bash: ./uname: No such file or directory
I don't know if the Linux ldd is supposed to work on these binaries, but it
doesn't:
manhack:/usr/gnemul/solaris/bin# ldd ./uname
/usr/bin/ldd: line 117: ./uname: No such file or directory
Running "/lib/ld-linux.so.2 --list" against the Solaris binary segfaults. I
would assume that is bad.
manhack:~# /lib/ld-linux.so.2 --list /usr/gnemul/solaris/bin/uname
Segmentation fault
From the Solaris machine (cds3), I ldd the binary I copied and verify all the
libraries are on the Linux host:
whardin@cds3 / $ cksum /bin/uname
2504107844 6772 /bin/uname
whardin@cds3 / $ ldd /bin/uname
libc.so.1 => /lib/libc.so.1
libdl.so.1 => /lib/libdl.so.1
/usr/platform/SUNW,Ultra-60/lib/libc_psr.so.1
manhack:~# cksum /usr/gnemul/solaris/bin/uname
2504107844 6772 /usr/gnemul/solaris/bin/uname
manhack:~# ls /usr/gnemul/solaris/lib
/usr/gnemul/solaris/usr/platform/SUNW,Ultra-60/lib/
/usr/gnemul/solaris/lib:
ld.so libc.so.1 libdl.so.1 libmp.so.2 libsecdb.so.1
libcmd.so.1 libcurses.so.1 libgen.so.1 libnsl.so.1
/usr/gnemul/solaris/usr/platform/SUNW,Ultra-60/lib/:
libc_psr.so.1
I'm stumped. I feel like I just missed a simple step somewhere, but haven't a
clue what. Anyone have any pointers or troubleshooting advice? I've
installed the libc6-dbg package but have no idea how to make use of it.
