This has been fixed in later releases of rusqlite (specifically >= 0.9.0). Is proper crates.io hygiene to go back and publish point releases that fix this for older versions? If so, how far back should I go?

[nikomatsakis]

@jgallagher what was the problem exactly?

And, I would say it is very kind of you to upgrade your point releases, definitely! The question of how far back to go is a good one. In this case, the problem is that some dependency likes 0.7.3, which is something you can't easily control...

[jgallagher]

@nikomatsakis No problem exactly - there was just a leftover build.rs at the project root that got committed by accident a long time ago. I don't think it was ever referenced by the project or Cargo.toml, but the changes to Cargo linked above made it problematic.

If https://crates.io/crates/rusqlite/reverse_dependencies is the right picture, looks like I should update back to 0.6.x?

[jgallagher]

@brson I pushed rusqlite 0.6.1, 0.7.4, and 0.8.1 which should fix this. 0.9 and up was already fixed.

Hello, am author of sphinxad.

I (and not just me) have made something and this is fixed in new version(0.1.2). But where are examples. Each is cargo project.
Dependency in Cargo.toml is sphinxad = "*"

• If I run with nighlty 1.17, It downloads sphinxad 0.1.0 and all works(0.1.0 has no build.rs file)
• But if I change to sphinxad="0.1.2", I get error failed to select a version for pkg-config.
• Bit if I crate new project with sphinxad = "*", it downloads 0.1.2 and all works perfect.

Why cargo do it? How to fix it?

[brson]

Seems like this is expected breakage and we just need to help people adapt.

I'll look at sending PRs to these crates.

So for these four crates:

• rusqlite-0.7.3: looks like @jgallagher has it handled.
• schemamama_rusqlite-0.5.0 this failed because of rusqlite0.6, and now pulls in 0.6.1, as it had a ^ dependency, so it's good to go.
• sphinxad-0.1.1 @TrionProg's comment above seems strange; @alexcrichton, maybe you know what's going on? It seems odd that 0.1.2 works in one context and not another.
• sphinxad-sys-0.1.2 see above

@TrionProg sorry for the slow response! It looks like you've already taken care of this and it looks like you've also published, so I don't think there's anything left to be done!

@TrionProg if you're still having trouble locally, could you gist the full error you're seeing and I'll help you debug?
