Hello,

We have a new EasyConfig file SOBAcl-r18.eb which has this in it:

    easyblock = "Tarball"

    name = 'SOBAcl'
    version = 'r18'

    toolchain = {'name': 'dummy', 'version': 'dummy'}

    dependencies = [('GraphViz', '2.18-intel-2014b-Perl-5.20.0')]



if you set the toolchain to intel-2015a change this to

dependencies = [('GraphViz', '2.18', '-Perl-5.20.0', True)]

True means, use the toolchain that's used for this easyconfig.
or if you keep dummy dummy you can specify:

dependencies = [('GraphViz', '2.18', 'Perl-5.20.0'', ('intel', '2015a')]
see 
http://easybuild.readthedocs.org/en/latest/Writing_easyconfig_files.html#dependencies

and possibly make this perl version a variable somewhere

I’ve tested this, and for me it works like this:

    toolchain = {'name': 'intel', 'version': '2014b'}

    perl = 'Perl'
    perlver = '5.20.0'
    versionsuffix = '-%s-%s' % (perl, perlver)

    dependencies = [('GraphViz', '2.18', versionsuffix, ('intel',
    '2014b'))]


This will work too, since the toolchain is already specified (and 
inherited by the dependencies):

    dependencies = [('GraphViz', '2.18')]


It doesn’t work if I specify the dependencies like this:

    dependencies = [('GraphViz', '2.18', versionsuffix, True)]


I found another example in the EasyConfig for 
DOLFIN-1.0.0-ictce-4.0.6-Python-2.7.3.eb, which has (among others):

    toolchain = {'name': 'ictce', 'version': '4.0.6’}
    dependencies = [
                    ('MTL4', '4.0.8878', '', True),
    ]


but when doing “eb —dry-run” we see:

     * [ ] easybuild/easyconfigs/m/MTL4/MTL4-4.0.8878.eb (module:
    MTL4/4.0.8878)


So shouldn’t it be just the opposite?

No, the 'True' means "use dummy toolchain for this dependency".

See
