Description Dennis Gilmore 2013-03-23 00:59:47 UTC

Support for the ARM 64 bit CPU architecture (aarch64) was introduced in 
autoconf 2.69.  libibverbs appears to use an earlier version of 
autoconf, preventing its being built.  This can be fixed in of three ways (In order of preference):

1. Work with upstream to migrate the package to autoconf 2.69.

2. Rerun autoconf or autoreconf in %prep or %build prior to running 
configure.

3. Apply the patch at http://ausil.fedorapeople.org/aarch64/libibverbs/libibverbs-aarch64.patch
which updates config.guess and config.sub to recognize aarch64.

If only updates to config.guess/config.sub are needed (just as proposed by patch in 3.), it's an upgraded automake package that's required: it's automake that provide config.guess/config.sub as part of automake --add-missing.

Anyway, config.guess / config.sub can be updated without updating automake.
The up-to-date version of those file can be downloaded from 
http://www.gnu.org/software/config/
http://git.savannah.gnu.org/cgit/config.git/tree/

Any versions from 2012-02-14 should support AArch64 (aka ARMv8).

I've checked libibverbs-1.1.7 available at:
http://www.openfabrics.org/downloads/verbs/libibverbs-1.1.7.tar.gz

Announcement for this release is available here:
http://article.gmane.org/gmane.linux.drivers.rdma/15786

It seems it has support for AArch64:

$ grep "Generated by GNU Autoconf" configure
# Generated by GNU Autoconf 2.69 for libibverbs 1.1.7.

$ grep "Makefile.in generated by" Makefile.in
# Makefile.in generated by automake 1.11.6 from Makefile.am.

$ grep ^timestamp= config/config.{guess,sub}
config/config.guess:timestamp='2012-02-10'
config/config.sub:timestamp='2012-04-18'

Comment 3 Yann Droneaud 2013-07-17 14:53:13 UTC

According to bug #969687, libibverbs-1.1.6 seems to be fixed to build for AArch64.

Regards.
