openbios compile issue, goal = solaris 8/9 (sparc64) under qemu
by Kristian Hermansen May 3, 2007

May 3, 2007

Hello! I am interested in running Solaris 8/9 under qemu. According to the thread below, it may be possible with more recent versions of OpenBIOS: http://qemu-forum.ipi.fi/viewtopic.php?p=10243 So I attempt to investigate. However, I am unable to build the alpha release of OpenBIOS from 20070427. I currently have qemu (20070501-svn-snapshot) Here are the details of my machine setup, and other variables, along with the output of the errors. administrator@ubuntu-khermans-desk:/tmp/openbios-devel$ uname -a Linux ubuntu-khermans-desk 2.6.20-15-generic #2 SMP Sun Apr 15 07:36:31 UTC 2007 i686 GNU/Linux administrator@ubuntu-khermans-desk:/tmp/openbios-devel$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=7.04 DISTRIB_CODENAME=feisty DISTRIB_DESCRIPTION="Ubuntu 7.04" administrator@ubuntu-khermans-desk:/tmp/openbios-devel$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz stepping : 9 cpu MHz : 2992.671 cache size : 512 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid xtpr bogomips : 5989.50 clflush size : 64 processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz stepping : 9 cpu MHz : 2992.671 cache size : 512 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid xtpr bogomips : 5985.43 clflush size : 64 administrator@ubuntu-khermans-desk:/tmp/openbios-devel$ ls -l /usr/bin/gcc* lrwxrwxrwx 1 root root 7 2007-04-05 21:37 /usr/bin/gcc -> gcc-4.1 -rwxr-xr-x 1 root root 80916 2007-01-03 15:22 /usr/bin/gcc-3.3 -rwxr-xr-x 1 root root 85044 2007-01-02 12:03 /usr/bin/gcc-3.4 -rwxr-xr-x 1 root root 183904 2007-03-02 21:52 /usr/bin/gcc-4.1 lrwxrwxrwx 1 root root 10 2007-04-05 21:37 /usr/bin/gccbug -> gccbug-4.1 -rwxr-xr-x 1 root root 15970 2007-01-03 15:17 /usr/bin/gccbug-3.3 -rwxr-xr-x 1 root root 16090 2007-01-02 11:57 /usr/bin/gccbug-3.4 -rwxr-xr-x 1 root root 16266 2007-03-02 21:47 /usr/bin/gccbug-4.1 -rwxr-xr-x 1 root root 2018 2006-12-20 09:41 /usr/bin/gccmakedep administrator@ubuntu-khermans-desk:/tmp/openbios-devel$ config/scripts/switch-arch cross-sparc64 administrator@ubuntu-khermans-desk:/tmp/openbios-devel$ make /usr/bin/xsltproc Building OpenBIOS on x86 for sparc64 Cleaning up... ok Initializing build tree...ok.

However, the google searches I made turned up only people on SPARC platforms running egcs64, so I am unsure what the requirements are to get to my intended goal -- Solaris 8/9 under qemu. Any help is greatly appreciated! Thanks :-) -- Kristian Hermansen
