 |
|
I recently created an ebuild for libspe2, version 2.1.0. Currently the latest version in the lu_zero's overlay is 2.1.0. I based it on libspe2-2.0.1.ebuild from lu_zero's overlay.
You'll need to put the following files in the files/ directory:
- The 3 patches from http://www.bsc.es/plantillaH.php?cat_id=306
- A patched version of the spe.rc6 file. I used the file from lu_zero and changed 'elfspe2' to 'elfspe'.
Until now I have had only few problems with libspe 2.1.0: With the latest kernel from git://git.kernel.org/pub/scm/linux/kernel/git/geoff/ps3-linux it is possible to create a program that completely hangs the ps3. Of course, this is a kernel problem: A normal user program shouldn't be able to do this.
This library provides both libspe1 and libspe2, so I've added an RDEPEND to make sure it won't be installed together with libspe1 (libspe).
In the ebuild you might want to modify some file paths.
