Subject: [lttng-dev] Support for new arch 'ppc64le'
Hi,
We are in the process of adding support for new architecture 'ppc64le'
(PowerPC 64 Little Endian) and as part of that, We have worked with libtool
maintainer to get alpha release (links below) which has all the needed bits
to support building on ppc64le arch.
ftp://alpha.gnu.org/gnu/libtool/libtool-2.4.2.418.tar.gz(1.6MB)
ftp://alpha.gnu.org/gnu/libtool/libtool-2.4.2.418.tar.xz(920KB)
(A stable libtool release is expected soon this year)
' userspace-rcu-0.8.1' didn't build on 'ppc64le' system because of outdated
libtoo.m4/config.guess files.
Latest ' liburcu' source package we picked is from :
http://lttng.org/files/urcu/userspace-rcu-0.8.1.tar.bz2
Along with changes to libtool related files, we have found a patch available
in ubuntu src repo, which is required to build 'liburcu' successfully on
'ppc64le' system.
Im attaching the same patch which is created on top of "liburcu-0.7.7-1"...
hence we request you to apply attached patch , and spin off a new version of
'liburcu' using the latest libtool alpha release . So that we can test
ppc64le fixes.
Your response is highly appreciated
Hi,
I see that the patch you propose adds both "powerpc64le" and "aarch64" entries.
Why are there two of them ?
I think the entry "aarch64" entry is related to arm64 archtype. I will
try to contact the original author of the patch and reconfirm.
Moreover, it might be a bit aggressive to package the liburcu tarballs with an
alpha version of libtool. When we
understand more about the need for one or two specific entries into the
configure.ac of liburcu, then we can add
them, but until there is a stable version of libtool supporting those, you will
probably have to create your own
tarballs from the userspace RCU git repository using "make dist" against your
alpha libtool.
okay.
Thoughts ?
Thanks,
Mathieu
