Hello list:
I am installing "libibverbs-1.1.4-GCC-4.6.3.eb", but I have problem
compiling gcc-4.6.3 as you can see below. My cluster in built in
Debian 8 amd64. Do you recommend CentOS to avoid some compatibility
issues or is fine any distro?
I think there are two problems here.
One issue is that you're trying to build an old GCC version on a modern
OS; there have been other reports on problems with this.
So, you're choice of using --try-toolchain to try building with a more
recent version of GCC is the right one, I'd say.
To respond to your question on Debian vs CentOS: EasyBuild should work
just a well on either, but is used more often on CentOS (or other RedHat
derivatives), and hence probably more stable than on Debian.
Nevertheless, if you run into problems on Debian-based systems, they're
bugs that we're not aware of yet (or which haven't been fixed yet), so
please do report them, either via the mailing list or by opening an
issue on GitHub.
The other problem is that you're installing libibverbs with EasyBuild.
Although you can make it work, as you've seen after using a recent GCC
and dealing with the download issue, it's probably not the best thing to do.
The reason why there are no easyconfig files for recent versions of
libibverbs is because we've realized that libibverbs is too closely
connected to the IB drivers provided by the OS (since you need root for
those).
Although you can install libibverbs with EasyBuild, as soon as the IB
drivers on your OS are updated, the build is likely rendered useless.
So, you'll need to rebuild libibverbs...
For libibverbs specifically, it's probably easier in the long run to
just use the one packaged by the OS.
This is also what we do in recent versions of OpenMPI: we specify that
libibverbs must be provided via the OS, via 'osdependencies' in the
corresponding easyconfig files.

In the attached log file
(easybuild-syIy3f-whit-different-toolchain-version.log), you can see
the line:
== 2016-01-07 08:50:44,129 runpy.filetools WARNING URL
http://www.openfabrics.org/downloads/libibverbs/libibverbs-1.1.4-1.24.gb89d4d7.tar.gz
was not found (HTTP response code 400), not trying again
The problem is that
"http://www.openfabrics.org/downloads/libibverbs/libibverbs-1.1.4-1.24.gb89d4d7.tar.gz";
don't redirect to
"https://www.openfabrics.org/downloads/libibverbs/libibverbs-1.1.4-1.24.gb89d4d7.tar.gz";
when you get previous link, instead if you get
"http://www.openfabrics.org/downloads/libibverbs";, its redirect to
https, may be a server configuration error... To solve this I
downloaded the tarball manually and copied it to my sources directory
(/home/CLUSTER/uclv.carlosbr/.local/easybuild/sources/l/libibverbs/),
the I repeated the previous command and worked fine!!
Any comments and suggestions are welcome!
The workaround you've used to deal with the download issue is the right
one: download manually, and provide it to EasyBuild by copying the
tarball to the EasyBuild source path.
To fix this, we have to update the 'source_urls' lines in the libibverbs
easyconfigs we include in the EasyBuild releases, to use https .

Kenneth
