v1.1.1 /darwin/sys/proctable.rb requires ffi but gemspec does not specify it.

[islador]

Hello,

I recently updated my sys-proctable version and found that it broke my build. The issue appears to be that sys-proctable's gemspec does not specify the dependency on ffi. Which means it doesn't get installed, and thus crashes everything.

@islador I have the ffi dependency set as far as I can tell. What is the output of gem spec sys-proctable?

      The sys-proctable library provides an interface for gathering information
      about processes on your system, i.e. the process table. Most major
      platforms are supported and, while different platforms may return
      different information, the external interface is identical across
      platforms.

Upon looking at this, I am even more confused. You're correct, it does list FFI as a runtime requirement. Yet when I include sys-proctable 1.1.1 in one gem, and then include that gem in another, the second gem of mine kicks an error for not having FFI. Perhaps it is my gemspec that is incorrectly specifying requirements?

[djberg96]

So, that should match gem dependency sys-proctable then. Is it possible that it's your environment, and you were require'ing an older version of sys-proctable that did not require ffi? What's your gem env output?

[islador]

We've solved this issue by explicitly requiring sys-proctable 1.0.0 after doing an assessment on FFI. I raised this issue after we traced your gem down as the cause. It seems we were wrong. Sorry for the trouble djberg96, thanks for the rapid response though!

[djberg96]

@islador No problem, glad you figured it out.
