make fails with error: parameter declared ‘auto’

[iraklic]

I am trying to build xrootd on CentOS Linux release 7.9.2009 (Core). I hope this is the right forum, if not please point me to the right one (I was not able to find it). Below is the dump:

Hi @iraklic ! are you aware of this? https://github.com/xrootd/xrootd/blob/v5.3.1/docs/ReleaseNotes.txt#L177
What compiler did you use?

[simonmichal]

@adriansev : thanks for pointing this out! :-)

@iraklic : on Centos7 for the build to be successful you need to enable at least devtoolset-7:

scl enablde devtoolset-7 bash

this will give you the right compiler.

[iraklic]

thanks for the replies. Looks like I will have to install devtoolset-7 and do it without sudo permission because scl enablde devtoolset-7 bash returns Unable to open /etc/scl/conf/devtoolset-7!

What is the easiest way to go by installing devtoolset without root permission. Just getting the rpm and doing rpm2cpio <devtoolset>.rmp | cpio -id only get me to having iraklic/centos/etc/yum.repos.d/CentOS-SCLo-scl-rh.repo but I cannot yum this repo without root, can I? I understand if this is not xrootd related question and does not belong here, but help is appreciated and might help others too. thanks

[adriansev]

@iraklic there is a typo in command: it should be:
scl enable devtoolset-7 bash
but this will start a new shell; for scripts and usage in local shell and easier usage you can just do:
source /opt/rh/devtoolset-7/enable (also you can check for this file before hand to be sure that devtoolset is installed)

[iraklic]

@adriansev devtoolset is not installed, hence my question about whether or not I can succeed installing it without root and if the answer is yes what is the most painless option. thanks

[xrootd-dev]

The instructions can be found here: https://www.softwarecollections.org/en/scls/rhscl/devtoolset-7/ Those indicate you need to have root privileges.

[iraklic]

thank you all for the responses, I will try to get devtoolset in place one way or another and if all works will report back to close this thanks

[adriansev]

@iraklic you can make use of software distributed by sft.cern.ch see /cvmfs/sft.cern.ch/README.md
you can try to do:
source /cvmfs/sft.cern.ch/lcg/contrib/gcc/7.3.0/x86_64-centos7/setup.sh and see how it goes

[iraklic]

unfortunately cvmfs is not available as well :(

[adriansev]

@iraklic well, then you can try in a vm to install the devtoolset and then copy it in a user-side location of that computer. AFAIK the enable script for activation is relative to it's own location, so if you put the content of /opt/rh/devtoolset-7 anywhere else it should work.
for building operations i begun to use containers instead of vms so you could also try those out.

[simonmichal]

@iraklic : do you still need some assistance or can we close this issue?

[iraklic]

You can close the issue. Thank you for all the help.
