[Qemu-devel] Building QEMU on PS3

[陳韋任]

Hi, all

  Is it possible to build qemu whose target is i386-linux-user on
a PS3 machine (Gentoo Linux/PowerPC).

  I am trying to do so, but it failed at compiling i386-linux-user/translate.o.

  Here is the system information:
------------------------------------------------------------------------
gcc (Gentoo 4.4.4-r2 p1.3, pie-0.4.5)
Linux ps3 2.6.37-rc6
------------------------------------------------------------------------

  And here is the compliation error:
------------------------------------------------------------------------
  CC    i386-linux-user/translate.o
gcc: Internal error: Killed (program cc1)
Please submit a full bug report.
See <http://bugs.gentoo.org/> for instructions.
make[1]: *** [translate.o] Error 1
make: *** [subdir-i386-linux-user] Error 2
------------------------------------------------------------------------

  Do I miss something? Any suggestion appreciated.

Regards,
chenwj

  Thanks for the info. I wonder if it is possible to cross compile qemu for
ppc (host) on a x86 machine.

If you have cross compile toolchain and cross compiled necessary
libraries, then it should work.
You can also try adding extra swap on PS3 to see if it can compile the sources.

Hi, Roy

  What I did is apply the patch (see attachment) which comment out an
assertion in tcg/tcg.c first. Then configure qemu with "--enable-debug"
option. I don't know if it is safe to remove the assertion though, but
it works for small program.
