Unsatisfiable constraint when no explicit package version given #10000
Description
Installing flux-core with an explicit version (i.e., [email protected], [email protected], flux-core@master) works perfectly. Attempting to install without an explicit version (i.e., spack install flux-core) fails when spack cannot seem to satisfy the lua dependency. It appears as though the concretizer just grabs tha latest version of lua (5.3.X) and then some other verification pass realizes that this doesn't meet the specification for the latest version of flux-core ([email protected] and [email protected]:5.2.99).
My guess is that this is either:
A) improper specification of dependencies in the flux-core package
B) a bug in the concretizer
Flux's lua dependency specification currently looks like:
depends_on("lua", type=('build', 'run', 'link'))
depends_on("[email protected]:5.1.99", when="@0.1.0:0.9.0")
depends_on("[email protected]:5.2.99", when="@0.10.0:,master")Does the when argument only apply when a user explicitly adds that variant/customization in the command?
