I tried out building https://github.com/xenserver/buildroot on CentOS 6.6


It builds around 300 packages and then it just gets stuck while building
ocaml-core-kernl-111.28.00-1.el6 .
build log: https://gist.github.com/gautammaloo/92a6199ee4ed100b1b92

I was looking for more upstream version of ocaml-core-kernel for el6. As
you were saying Jonathan is already working on that
http://copr-be.cloud.fedoraproject.org/results/jonludlam/ocaml402/epel-6-x86_64/
.

I am hoping if ocaml4.02 is ready by May,2015 I could use to build xapi
for CentOS 6.6. Meanwhile I can try out
https://github.com/xenserver/buildroot on CentOS 6.5.

Best regards,
Gautam Malu

Hi Gautam,

From the log it looks like it ran out of space - this could be the disk being
full, but it could also be that it might be building in a tmpfs environment
and you're actually running out of memory.

try changing the mock config in buildroot.git/mock/default.cfg - the line is:

config_opts['plugin_conf']['tmpfs_enable'] = True

change that to 'False' and see if that helps.

Jon

Thanks Jon,
it worked, I was able to build all the packages for xenserver on CentOS 6.6
final version.

Here is the package list:
https://gist.github.com/gautammaloo/7616cccbe8f5c85c196e

I was wondering what packages would be necessary to use Xen with xapi, I
already have xen with xl installed. Could we have a package like
http://packages.ubuntu.com/precise/xcp-xe with which we can have xenserver
running on CentOS, just by switching toolstack from xl to xapi.

Best regards,
Gautam Malu
