How to install split IMAS  using EasyBuild

This tutorial shows how to install IMAS (after repository split) using EasyBuild. The installation in this tutorial will be performed on the Gateway cluster but it can be done anywhere.

...

  • eb - EasyBuild

  • IMAS-AL-Cpp/IMAS-AL-Cpp-5.2.0dev-foss-2020b-DD-3.40.1.eb - path to EasyBuild configuration file

  • --allow-modules-tool-mismatch - flag
  • --robot - paths to configuration files
  • --http-header-fields-urlpat - secret to downloading files from ITER repo

Useful tips

Increasing the length of error/warning message

Easybuild shows only the first 300 characters of error/warning message and cuts (usually the most interesting) remaining part of the message.

The message length value is hardcoded and can be change only by 'hacking' the EB codes:

  1. Open <easybuild virtual env>/lib/python3.10/site-packages/easybuild/framework/easyblock.py 
  2. Look for value "300" (line 4295 in EB version 
    Code Block
    titleeasyblock.py
    except EasyBuildError as err:
        first_n = 300   # <=== HERE is the limit hardcoded 
        errormsg = "build failed (first %d chars): %s" % (first_n, err.msg[:first_n])  
        _log.warning(errormsg)
        result = False
  3. Increase the limit to bigger value (e.g. 3000) or remove the message cutting err.msg[:first_n])  ==> err.msg 
  4. Save the file    


Other

  • If you have compilation problems try adding the --parallel=1  option
  • If you have problem with Perl : 
    Code Block
    make[1]: Entering directory `/afs/gw/swimas/easybuild/opt/build/Perl/5.38.0/GCCcore-13.2.0/perl-5.38.0/utils'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/afs/gw/swimas/easybuild/opt/build/Perl/5.38.0/GCCcore-13.2.0/perl-5.38.0/utils'

        Everything is up to date. Type 'make test' to run test suite.
./perl -Ilib -I. installperl --destdir=
mkdir /afs/.gw: Read-only file system at ./install_lib.pl line 146.
make: *** [install-all] Error 30
 (at easybuild/tools/run.py:682 in parse_cmd_output)
    The reason may be the installation path starting with /afs . Try changing it.
  • If you have problem with cairo  and old ttx you can link old ttx  to /usr/bin/true .
  • Problem with IMAS modules → change easyblock to Bundle
