[Cbe-oss-dev] elfspe/elfspe2 source code (SRPMS)?

[Wang, Baojun]

hi, 

I've installed gentoo 2007.0 (ppc64, 64bit userland) on ps3 successfully, and 
I'm trying to build the spu toolchain on ps3, the toolchain has been built 
successfully, which is including:

spu-binutils, spu-gcc, spu-gcc-c++, libspe, libspe2, spu-newlib and spu-gdb. 

spu-gcc can generate executable, the problem is I can't got it (the standalone 
spu program) run on the gentoo/ps3 box. however, the executable (hello, 
spu-gcc -o hello hello.c, hello world example.) can run on systemsim (SDK 
2.1) and yellowdog Linux (5.04) on ps3. I have follow all instructions from 
the documentation (althrough not for gentoo) including:

1) build all above packages (spu-binutils, spu-gcc, ...) via src.rpm on ps3.

     rpm -Uvh xxx.src.rpm
     rpmbuild -ba --nodeps --target=ppc64 /usr/src/rpms/SPECS/xxx.spec
     rpm -Uvh --nodeps /usr/src/rpms/RPMS/ppc64/xxx.rpm

2) install elfspe2-xxx.ppc.rpm, elfspe/elfspe2 package is ONLY BINARY 
AVALIABLE (which I think cause problem in my example):

     rpm -Uvh --nodeps elfspe2-xxx.ppc.rpm
     
  The package is (I guess) for YellowDog Linux or Fedora Core 6, I have modify 
to fit my gentoo box such as /etc/init.d/elfspe and add it to the default run 
level.

3) mount neccessary filesystem:

     mount -t spufs none /spu
     mount -t binfmt_misc none /proc/sys/fs/binfmt_misc

4) run elfspe to register so that we can standalone spu program:

     /etc/init.d/elfspe start

5) run our test program:

  a) standalone spu program is not working:

     spu-gcc hello.c -o hello-spu

  when I ran:

     ./hello-spu

  I got the following error message:

     bash: ./hello: Accessing a corrupted shared library

  b) mixed spu/ppu program is working:

BTW: 

1) the kernel is from gentoo ps3 live CD (2.6.16-ps3), I've also tested the 
kernel from YellowDog Linux 5.04 for PS3, it's still the same. the CD is 
from: 
http://ps3.keshi.org/debian-live/20070114/debian-live-ps3pf-20070114.iso

2) all RPMS and SRPMS are downloaded from BSC:
http://www.bsc.es/projects/deepcomputing/linuxoncell/cellsimulator/sdk2.1/

I think the most possibility is elfspe have a problem, it can't run the 
standalone spu program (as a interpreter via binfmt_misc), since mixed 
spu/ppu program works fine. the elfspe package is only binary avaliable, and 
when I use `readelf -s /usr/bin/elfspe`, it have many symbol link against to 
GLIBC2.4, while gentoo 2007.0 is using glibc-2.5.

Is there any thing wrong in my configuration? Is elfspe/elfspe2 source 
avaliable ( I can't found it and I've googled many times) so I can build it 
from source, or is it possible elfspe/elfspe2 source code being avialiable 
later?

Thanks in advance!

  Regards,

Wang
