Oh, and am I right in that the robot search path is used for the
resolution, even when --robot isn't actually used as an option?

Hi,
Could anybody please describe the dependency resolution in EB in a few
lines for me? I've been trying to get an unambigious mental picture of
it but get confused by the combination of documentation (see below),
prior experience on our site and some testing we did yesterday.
The main point I'm trying to get clear is wether
A) EB looks for installed *modules* when it determines if dependencies
are available (regardless if corresponding easyconfigs are available) or
B) wether it determines easyconfigs for dependencies and then checks if
there's installed modules for those configs.
We have --minimal-toolchains and --use-existing-modules enabled since a
few weeks and I get the impression it changed situation A into B. EB
used to be able to find a dependency when it was installed as a module,
but now it seems to search for the easyconfig (which it can't find as
they're not in the global installation in my case) and ignores the
installed module
The docs seems to point to A, with B needed in certain situations (but
which those are stays a bit fuzzy).
Regards,
Paul

"Unless dependency resolution is enabled, EasyBuid requires that modules
are available for every dependency"

"For each dependency that does not have a matching module installed yet,
EasyBuild requires a corresponding easyconfig file."
"Sometimes easyconfig files are needed even when the modules for the
dependencies are already available, i.e., whenever the information
provided by the dependency specification (software name/version,
toolchain and version suffix) is not sufficient."
