[julia-users] BinDeps: non-library dependencies

Hi all, Using BinDeps, is there currently any way to specify binary dependencies which are not libraries? I can envision this being useful for declaring a build-time dependency on executables like pkg-config or cmake. Likewise, is there a way to declare a dependency on a set of headers? For

Definitely doesn't work that way. If I check both orderings the code to fix (5) works. You might be thinking of promote, not promote_rule. That's not a useful function though because it tries to convert values to a given type, which is basically useless for things like a conversion to

That is not supposed to be how it works! As I recall there was a meetup where JeffB explains that promote_rule always never cares about the order of its arguments and internals generate lookups for both orderings. On Tuesday, March 22, 2016 at 6:26:51 PM UTC-4, Bill Hart wrote: > > OK I

OK I solved (5). Apparently promote_rule needs to be defined for both orderings of its arguments if one wants it to work with arguments in either order. I can't think of any reason why one wouldn't expect a promote_rule to come up with a common type to which both can be promoted, regardless of

Another problem: 5) We have been using promote_type to find out the type returned by a promote_rule we defined, which has mostly worked fine, oddly enough. But now that I realise that's not what promote_type is for, I switched to using promote_rule instead, since it just returns Union{} if

Apparently, promote_type doesn't return the type you get from a promote_rule, but the smallest type which can contain both types, which apparently doesn't have to be a concrete type or even something you get from a promote_rule! That's really confusingly named! That means we are using

This is proving impossible to work around. Firstly, I can't seem to produce a minimal example of the behaviour I just mentioned. If the promote_rule_exists function is placed in the Nemo module itself it returns a different value to if I define the function at the REPL. But if I place it in a
